-Index of the documented template contexts for Datasette's core HTML pages.
-
-This module deliberately contains no documentation strings of its own -
-the documentation lives next to the code it describes:
-
-- Every page renders a Context dataclass defined in its view module
-  (DatabaseContext, QueryContext in views/database.py, TableContext in
-  views/table.py, RowContext in views/row.py). Fields added by view code
-  carry ``help`` metadata; fields declared with from_extra() take their
-  documentation from the description on the matching Extra class in
-  views/table_extras.py.
-- The keys render_template() adds to every page are documented in
-  TEMPLATE_BASE_CONTEXT in datasette/app.py, next to the code that adds
-  them.
-
-The contract tests in tests/test_template_context.py assert that the real
-rendered context for each page exactly matches what is documented, and
-docs/template_context_doc.py generates docs/template_context.rst from the
-same classes.

 Changelog
 =========
 
-.. _v1_0_a36:
-
-1.0a36 (2026-07-07)
--------------------
-
-The signature features of this alpha are new UIs for **inserting multiple rows at once** (from TSV, CSV or JSON) and for **creating a table from rows**, plus a large number of small **JSON API consistency fixes** in preparation for a 1.0 stable release.
-
-- Table pages now offer an "Insert multiple rows" mode in the row insertion dialog. This accepts pasted TSV, CSV or JSON, previews the parsed rows before inserting them, validates unknown columns as data is pasted and displays omitted auto integer primary keys as ``auto`` in the preview. (:pr:`2813`)
-- The bulk insert UI can skip rows with existing primary keys, or update existing rows and insert new rows using the existing ``/<database>/<table>/-/upsert`` API when the actor has both :ref:`insert-row <actions_insert_row>` and :ref:`update-row <actions_update_row>` permissions. (:pr:`2813`)
-- The "Create table" dialog now includes a "Create table from data" mode. Paste TSV, CSV or JSON rows to preview inferred columns and types, choose the table name and primary key, then create the table and insert those rows in one step. (:pr:`2813`)
-- Datasette's JSON APIs now consistently encode every ``BLOB`` value using the documented :ref:`binary value JSON format <binary_json_format>`, even when the bytes could be decoded as UTF-8 text. (:issue:`2806`, :pr:`2822`)
-- The insert and edit row dialogs now provide a dedicated control for ``BLOB`` values. Existing binary values are shown by byte size, image values under 10MB are previewed as thumbnails, and replacements can be attached, dropped or pasted into the control. (:issue:`2806`, :pr:`2822`)
-- The table and row JSON APIs now support ``?_extra=column_details`` for returning SQLite schema details for columns, including declared type, SQLite affinity, primary key, ``NOT NULL``, default and hidden-column metadata.
-- POST bodies that Datasette reads fully into memory - such as JSON submitted to the write API - are now capped by the new :ref:`setting_max_post_body_bytes` setting, defaulting to 2MB. Oversized requests are rejected with an HTTP 413 error as soon as the limit is exceeded, protecting smaller servers from memory exhaustion. File uploads are unaffected - ``request.form()`` streams those to disk and has its own separate limits. (:issue:`2823`)
-- Row pages for tables with compound primary keys now return a ``400`` error instead of a ``500`` error when the URL row identifier does not contain the correct number of primary key values. Thanks, `Zain Dana Harper <https://github.com/HarperZ9>`__. (:issue:`2811`, :pr:`2815`)
-- The :ref:`execute-write-sql <actions_execute_write_sql>` interface now supports ``CREATE VIEW`` and ``DROP VIEW`` statements, gated by the new :ref:`create-view <actions_create_view>` and :ref:`drop-view <actions_drop_view>` permissions. (:issue:`2819`, :pr:`2818`)
-- Saved-query SQL analysis now handles recursive CTEs, fixing a bug where storing a valid read-only recursive query could be disabled by SQLite's internal ``SQLITE_RECURSIVE`` authorizer callback. (:issue:`2809`, :pr:`2812`)
-- ``named_parameters()`` now correctly ignores SQLite comment markers that appear inside string literals, so query forms no longer drop later ``:named`` parameters from SQL such as ``select '--' || :name``. Thanks, `JSap0914 <https://github.com/JSap0914>`__. (:pr:`2783`)
-- Datasette's internal database schema is now managed using `sqlite-utils migrations <https://sqlite-utils.datasette.io/en/stable/python-api.html#migrations>`__, using the new dependency on ``sqlite-utils>=4.0``. (:issue:`2827`)
-- ``datasette.utils.CustomJSONEncoder`` is now documented as a public API for plugins that need to serialize Datasette values to JSON. Thanks, `Chris Amico <https://github.com/eyeseast>`__. (:issue:`1983`, :pr:`1996`)
-
-This release also includes the results of a `detailed consistency review <https://github.com/simonw/datasette/pull/2824>`__ of Datasette's JSON API in preparation for the 1.0 stable release. Several of these changes are backwards-incompatible with previous 1.0 alphas. The new :ref:`API stability documentation <json_api_stability>` describes exactly which parts of the JSON API are covered by the 1.0 stability promise.
-
-JSON API: breaking changes
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-- JSON error responses now use a single canonical format across every endpoint: ``{"ok": false, "error": "...", "errors": [...], "status": 400}``. The ``error`` key joins all error messages together, ``errors`` is the full list of messages and ``status`` always matches the HTTP status code. The legacy ``title`` key is no longer included in JSON errors (it remains available to the HTML error template), and endpoints that previously returned bare ``{"error": ...}`` objects have been updated. See :ref:`json_api_errors`.
-- Every JSON object success response now includes ``"ok": true``, including introspection endpoints such as ``/-/versions`` and ``/-/settings``.
-- ``/-/plugins.json``, ``/-/databases.json`` and ``/-/actions.json`` now return objects - ``{"ok": true, "plugins": [...]}`` and equivalents - instead of top-level JSON arrays, so these responses can gain additional keys in the future without a breaking change. The ``datasette plugins`` CLI command still outputs a plain array.
-- ``/-/databases`` now only lists databases the current actor is allowed to view. It previously listed every attached database, including their filesystem paths, to any actor with ``view-instance``.
-- Requests with an invalid or expired ``Authorization: Bearer`` token now receive a ``401`` status with the standard error body and a ``WWW-Authenticate: Bearer error="invalid_token"`` header, instead of being silently treated as unauthenticated. Bearer tokens that no registered token handler recognizes are still ignored, so authentication plugins with their own token formats keep working. Plugin :ref:`token handlers <plugin_hook_register_token_handler>` can raise the new ``datasette.TokenInvalid`` exception to trigger the same behavior.
-- Permission errors for JSON requests now return the standard JSON error format with a ``403`` status. The default forbidden handling previously rendered an HTML error page even for ``.json`` requests.
-- ``POST`` to a write canned query now returns a ``400`` error when the SQL fails to execute, instead of a ``200`` status with ``"ok": false`` in the body. The error response includes the standard error keys plus a ``"redirect"`` key.
-- The :ref:`row update API <RowUpdateView>` with ``"return": true`` now responds with a ``"rows"`` list, matching insert and upsert, instead of a singular ``"row"`` object.
-- Row delete write failures - such as a constraint violation raised by a trigger - now return ``400`` instead of ``500``, matching the other write endpoints.
-- ``/<database>/-/query.json`` with a missing or blank ``?sql=`` parameter now returns a ``400`` error, as the CSV format already did, instead of a ``200`` with empty rows.
-- Unknown ``?_extra=`` names now return a ``400`` error for JSON and other data formats, instead of being silently ignored. HTML pages continue to ignore unknown names.
-- Table JSON responses now include ``next_url`` alongside ``next`` by default - both are ``null`` on the final page. The now-redundant ``?_extra=next_url`` parameter has been removed.
-- The stored query list JSON no longer includes ``has_more`` - ``"next": null`` is the end-of-results signal across the whole API. This change also uncovered and fixed a bug where the query list ``next_url`` pointed at the HTML page and was a relative path; it is now an absolute URL that preserves the requested format.
-- Stored query JSON objects no longer duplicate the list of parameter names as both ``params`` and ``parameters`` - only ``parameters`` remains. The query create and update APIs no longer accept ``params`` as an input alias either; ``params`` is still the documented key for :ref:`queries defined in configuration <queries_named_parameters>`.
-- Page size parameters are now consistent across the API: the stored query lists accept ``?_size=max`` and return a ``400`` error for values over the maximum instead of silently clamping them, and the ``/-/allowed`` and ``/-/rules`` permission debug endpoints renamed their ``page`` and ``page_size`` parameters to ``_page`` and ``_size``, matching the underscore grammar used by every other Datasette system parameter.
-- ``/-/threads`` now requires the ``permissions-debug`` permission, since it exposes runtime internals such as file paths. It previously only required ``view-instance``.
-- Trusted stored queries - those defined in configuration - can no longer be deleted through the JSON API or web interface, matching the existing restriction on editing them.
-- The ``/<database>/-/schema`` endpoints now check the ``view-database`` permission before checking whether the database exists, so unauthorized actors can no longer probe for the existence of databases.
-- SQL time limit errors in JSON responses are now a plain text message. The error string previously embedded an HTML fragment.
-- The undocumented homepage JSON at ``/.json`` now returns ``databases`` as a list of objects rather than an object keyed by database name, matching every other collection in the API.
-- The legacy ``.jsono`` format extension, long since superseded by ``?_shape=``, has been removed.
-
-JSON API: other improvements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-- The :ref:`write API <json_api_write>` endpoints now parse the request body as JSON regardless of the ``Content-Type`` header, so ``curl -d`` invocations work without remembering to set it. Invalid JSON is a ``400`` error. Cross-site request forgery remains prevented by Datasette's ``Origin`` and ``Sec-Fetch-Site`` checks. This also fixes a ``500`` error from the insert API when the ``Content-Type`` header was missing entirely.
-- New ``Response.error(messages, status=400)`` helper for plugins that need to return a JSON error in Datasette's standard format. See :ref:`internals_response`.
-- New ``count_truncated`` extra for table JSON, included automatically whenever ``count`` is requested. ``true`` means the count reached Datasette's counting limit and the real number of rows may be higher. See :ref:`json_api_extra`.
-- JSON endpoints that are not part of the documented stable API now declare themselves with an ``"unstable"`` key in their responses.
-- New documentation covering the grammar for :ref:`boolean query string arguments <json_api_table_arguments>`, the reason :ref:`upsert <TableUpsertView>` returns ``200`` where insert returns ``201``, and advice for plugin authors on :ref:`naming secret configuration keys <plugins_configuration_secret>` so that ``/-/config`` redacts them automatically.

-
-1.0a35 (2026-06-23)
--------------------
-
-This release adds UI for **creating tables** and **altering tables**, to complement the insert and update row interfaces added in :ref:`v1_0_a34`.
-
-- New "Create table" interface in the database actions menu, backed by the ``/<database>/-/create`` :ref:`JSON API <TableCreateView>`. It can define columns, primary keys, custom column types, ``NOT NULL`` constraints, literal defaults, expression defaults and single-column foreign keys. (:issue:`2787`)
-- New "Alter table" table action and ``/<database>/<table>/-/alter`` :ref:`JSON API <TableAlterView>` for changing existing tables: add, rename, reorder and drop columns; change column types, defaults, ``NOT NULL`` constraints, primary keys and foreign keys; and rename the table. The alter table dialog also includes a "Drop table" button. (:issue:`2788`)
-- New ``/<database>/-/foreign-key-targets`` and ``/<database>/<table>/-/foreign-key-suggestions`` JSON APIs for discovering valid single-column foreign key targets and suggested relationships.
-- New :ref:`template_context` documentation listing the variables available to custom templates for Datasette's core pages. Variables documented there are treated as a stable API for custom templates until Datasette 2.0. The documentation is generated from dataclass definitions next to the view code, with tests that compare the documented fields against the actual contexts rendered by the database, table, query and row pages. (:issue:`1510`, :issue:`2127`, :issue:`1477`, :pr:`2803`)
-- The "Write to this database" page now includes a Create table starter template, alongside the existing Insert, Update and Delete templates. (:pr:`2794`)
-- New ``static()`` template function and ``datasette.static()`` method for generating cache-busting static asset URLs based on the file contents. Static assets served with a matching ``?_hash=`` parameter now receive far-future immutable cache headers. This works for Datasette's bundled static assets, plugin static assets and directories mounted using ``--static``. See :ref:`customization_static_files`.
-- Database and table pages now use the ``count_truncated`` template context value to display capped row counts as ``>N rows``.
-- Significant visual improvements to the table filter form UI, plus working add/remove filter buttons. (:issue:`2798`)
-- Improved edit row icon on table pages. (:issue:`2796`)
-- Documentation covers how actors are displayed. Thanks, `Sebastian Cao <https://github.com/cycsmail>`__. (:issue:`2002`)
-- Fix for bug where appending ``?_col=pk`` resulted in duplicate primary key columns in the response. Thanks, `Ritesh Kewlani <https://github.com/riteshkew>`__. (:issue:`1975`)
-
-.. _v1_0_a34:
-
-1.0a34 (2026-06-16)
--------------------
-
-The big feature in this alpha is tools to **insert, edit and delete** rows within the Datasette interface. These features are available on table pages, and edit and delete are also available as action items on the row page.
-
-The edit interface takes :ref:`custom column types <table_configuration_column_types>` into account. Plugins that define their own column types can use JavaScript to customize how those column types are presented in the edit interface.
-
-- ``datasette.allowed_many()`` method for :ref:`resolving multiple permission checks at once <datasette_allowed_many>`. (:pr:`2775`)
-- Permission checks are now cached on a per-request basis, speeding up table pages with multiple plugins that check permissions in order to populate the :ref:`table actions menu <plugin_hook_table_actions>`.
-- Fixed a warning about ``gen.throw(*sys.exc_info())``. (:issue:`2776`)
-- New default custom column type ``textarea`` for multi-line text content. This is rendered as a ``<textarea>`` input in the edit UI.
-- The ``json`` column type now implements client-side validation in the edit UI.
-- The :ref:`makeColumnField() <javascript_plugins_makeColumnField>` JavaScript plugin hook allows plugins to define custom fields in the edit interface for their custom column types.
-- New UI for inserting, editing, and deleting rows within Datasette. (:issue:`2780`)
-- New ``/<database>/<table>/-/autocomplete?q=term`` :ref:`autocomplete JSON API <TableAutocompleteView>` for rapid autocomplete search against the contents of a table. This is used by the edit interface to select related rows for foreign keys. You can try it out on the ``/-/debug/autocomplete`` debug page.
-- New ``/<database>/<table>/-/fragment`` :ref:`HTML fragment endpoint  <TableFragmentView>` for returning the HTML used to display a specific row.
-- ``await request.json()`` utility method for consuming the request body as JSON. (:issue:`2767`)
-- Database, table, query and row action menus can now be modified by plugins to :ref:`display buttons in addition to links <plugin_actions>`. (:issue:`2782`)

-.. _v1_0_a33:
-
-1.0a33 (2026-06-11)
--------------------
-
-Stored queries can now be edited and deleted through the web interface, and the JSON API ``?_extra=`` mechanism has been extended to cover row and query pages in addition to tables. This release also fixes two security issues: an identifier-quoting bug involving table and column names that contain ``]``, and an open redirect.
-
-Editing and deleting stored queries
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The stored query page gained a "Query actions" menu with **Edit this query** and **Delete this query** links for actors with the necessary permissions. The owner of a query can always edit or delete it; for queries that are not private, any actor with the :ref:`update-query <actions_update_query>` or :ref:`delete-query <actions_delete_query>` permission can do so too. Private queries remain editable and deletable only by their owner. See :ref:`stored_queries` for details. (:issue:`2735`)
-
-``?_extra=`` support for row and query pages
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Row and query JSON pages now support the same ``?_extra=`` mechanism as table pages. Row pages can request extras such as ``foreign_key_tables``, ``query``, ``metadata`` and ``database_color``; arbitrary SQL and stored query pages can request extras such as ``columns``, ``query``, ``metadata`` and ``private``. The implementation was refactored into a registry of extra classes shared by all three page types.
-
-New generated reference documentation describes every ``?_extra=`` parameter available on table, row and query JSON pages, with example output captured from a live Datasette instance at documentation build time. See :ref:`json_api_extra` for the full list.
-
-You can explore the new extras using this `Datasette extras API explorer tool <https://tools.simonwillison.net/datasette-extras-explorer>`__.
-
-Other improvements and fixes to the extras mechanism:
-
-- Extras that exist to serve the HTML interface (``filters``, ``actions``, ``display_rows``) are no longer advertised or reachable through the JSON API, where requesting them previously returned a 500 serialization error.
-- The pre-1.0 ``?_extras=`` (plural) parameter on row pages has been removed - use ``?_extra=foreign_key_tables`` instead.
-
-Security fixes
-~~~~~~~~~~~~~~
-
-- Fixed an identifier-quoting bug in ``datasette.utils.escape_sqlite()``. Datasette uses this helper when constructing SQL around table and column names; identifiers containing ``]`` could break out of SQLite bracket quoting and alter the generated SQL, for example by adding a ``UNION SELECT``. Identifiers containing ``]`` are now quoted using double quotes instead. (:issue:`2677`)
-- Fixed an open redirect vulnerability. Requesting a path such as ``/\example.com/`` produced a redirect with a ``Location: /\example.com`` header - browsers normalize backslashes to forward slashes, turning that into the protocol-relative URL ``//example.com`` and redirecting the user off-site. Any run of leading slashes and backslashes in a redirect path is now collapsed to a single slash. (:issue:`2680`)
-
-Bug fixes
-~~~~~~~~~
-
-- ``can_render()`` callbacks registered by the :ref:`register_output_renderer() <plugin_register_output_renderer>` plugin hook now receive the result ``rows`` and ``columns`` for stored queries. Previously renderers that inspect the available columns - such as `datasette-atom <https://github.com/simonw/datasette-atom>`__ and `datasette-ics <https://github.com/simonw/datasette-ics>`__ - never appeared as export options on stored query pages. (:issue:`2711`)
-- Fixed a 500 error from the :ref:`/-/check <PermissionCheckView>` permission debugging endpoint when checking query actions such as ``view-query``, ``update-query`` and ``delete-query``. (:issue:`2756`)
-- Write queries that use a named parameter called ``:sql`` no longer fail with an error. (:issue:`2761`)
-- :ref:`db.execute_isolated_fn() <database_execute_isolated_fn>` now works against immutable databases, using a read-only connection that bypasses the write thread. It previously always attempted to open a writable connection, which would fail - breaking features built on top of it, such as the SQL analysis step used when storing a query. An exception raised while opening the connection for an isolated function no longer crashes the write thread. (:issue:`2768`)
-- Facet counts are now displayed on the same line as the facet value instead of wrapping onto a second line. (:issue:`2754`)
-- Datasette's pytest plugin no longer imports the rest of Datasette at pytest startup time. This means plugin test suites using ``pytest-cov`` now correctly record coverage of code that runs when ``datasette`` modules are first imported.

-
-1.0a32 (2026-05-31)
--------------------
-
-SQLite INSERT ... RETURNING clauses are now supported by ``/db/-/execute-write``, plus several fixes relating to the :ref:`base_url setting <setting_base_url>`.
-
-- ``INSERT``/``UPDATE``/``DELETE`` statements that use SQLite's ``RETURNING`` clause now work correctly in the new ``/db/-/execute-write`` interface. Datasette fetches returned rows before committing the write transaction, displays them in the HTML UI and includes them in the ``"rows"`` key for the JSON API response. (:issue:`2762`, :pr:`2763`)
-- ``Database.execute_write()`` now returns an ``ExecuteWriteResult`` object instead of the raw ``sqlite3.Cursor`` returned by ``conn.execute()``. The new object exposes ``.rowcount``, ``.lastrowid``, ``.description``, ``.truncated`` and ``.fetchall()``, and adds ``return_all=`` and ``returning_limit=`` options for controlling how rows from ``RETURNING`` statements are buffered. (:pr:`2763`)
-- Fixed the ``/-/jump`` navigation search endpoint when Datasette is served with a configured ``base_url``. (:issue:`2757`)
-- Fixed JSON and CSV export links, plus ``Link:`` alternate headers, on table, row and query pages when ``base_url`` is configured. These could previously be prefixed twice. (:issue:`2759`)
-- Fixed several other ``base_url`` handling bugs, including the API explorer form actions and share links, the ``/-/patterns`` development page, permanent redirects such as ``/-`` to ``/-/`` and database query redirects from ``/<database>?sql=...`` to ``/<database>/-/query?sql=...``.
-
-.. _v1_0_a31:
-
-1.0a31 (2026-05-28)
--------------------
-
-Datasette now offers users with the necessary permissions the ability to both **execute write queries** against their database and to **save stored queries** (renamed from "canned queries") both privately and for use by other members of their Datasette instance.
-
-The ability to write is controlled by the new ``execute-write-sql`` permission, but the user also needs the relevant ``insert-row``/``update-row``/``delete-row``/``create-table``/etc permissions for the query they are trying to execute.
-
-Write SQL UI
-~~~~~~~~~~~~
-
-- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted, includes starter templates for ``INSERT``, ``UPDATE`` and ``DELETE`` statements and links to a newly inserted row when a single-row insert succeeds. This is also available as a :ref:`JSON API <ExecuteWriteView>`. (:issue:`2742`)
-- Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
-- The write SQL analyzer now uses a deny-by-default model for unsupported operations. Reads from source tables require :ref:`view-table <actions_view_table>` permission, schema changes require :ref:`create-table <actions_create_table>`, :ref:`alter-table <actions_alter_table>` or :ref:`drop-table <actions_drop_table>` as appropriate, and row mutation statements require the full ``insert-row``, ``update-row`` and ``delete-row`` permission set. SQL functions are allowed and are not separately permission-gated. (:issue:`2748`)
-- User-supplied write SQL rejects both ``VACUUM`` operations and writes to SQLite virtual or shadow tables. These restrictions also apply to untrusted stored write queries; trusted queries in ``datasette.yml`` skip these filters. (:issue:`2748`)
-
-Stored queries
-~~~~~~~~~~~~~~
-
-- The previous "canned queries" feature has been renamed and expanded into :ref:`stored queries <stored_queries>`. Queries configured in ``datasette.yaml`` are now loaded into a new ``queries`` table in Datasette's :ref:`internal database <internals_internal_schema>`, alongside user-created stored queries. (:issue:`2735`)
-- New stored query management API methods available to plugins: ``datasette.add_query()``, ``datasette.update_query()``, ``datasette.remove_query()``, ``datasette.get_query()``, ``datasette.list_queries()`` and ``datasette.count_queries()``. These replace the removed ``datasette.get_canned_query()`` and ``datasette.get_canned_queries()`` methods. (:issue:`2735`)
-- Users with :ref:`store-query <actions_store_query>` and :ref:`execute-sql <actions_execute_sql>` permission can create stored queries from the SQL query page or the new ``GET /<database>/-/queries/store`` form. (:issue:`2735`)
-- The database page now shows a count and preview of stored queries, capped at five, and links to new paginated query lists at ``/-/queries`` and ``/<database>/-/queries``. Those pages support search. (:issue:`2735`)
-- Stored queries created by users default to private and untrusted. Private stored queries can only be viewed, updated or deleted by their owner, even if another actor has broad ``view-query``, ``update-query`` or ``delete-query`` permission. Untrusted stored queries execute using the permissions of the actor running them. See :ref:`stored_queries` and :ref:`trusted_stored_queries` for details. (:issue:`2735`)
-- Configured queries from ``datasette.yaml`` are trusted by default, so they can execute with ``view-query`` permission alone. They can opt out of that behavior using ``is_trusted: false`` but cannot be made private; private queries are only available for user-created stored queries. (:issue:`2735`)
-- New ``store-query``, ``update-query`` and ``delete-query`` permissions, plus updated semantics for :ref:`view-query <actions_view_query>`. Trusted stored queries can still execute with ``view-query`` alone; untrusted read queries also require :ref:`execute-sql <actions_execute_sql>` and untrusted writable queries require :ref:`execute-write-sql <actions_execute_write_sql>` plus the relevant table-level write permissions. (:issue:`2735`)

-Documented template contexts
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Datasette's documented template contexts are part of the public API for custom templates. They are defined as dataclasses next to the view code that renders them, for example ``DatabaseContext`` and ``QueryContext`` in ``datasette/views/database.py``.
-
-Every documented context class inherits from ``datasette.views.Context``. Fields that are added directly by view code should be declared as dataclass fields with ``help`` metadata, which is used to generate :ref:`template_context`. Fields resolved through the page extras system should use ``from_extra()`` so their documentation comes from the matching ``Extra`` class.
-
-Use ``documented_template`` on each context class to record the canonical template named in the generated documentation. This should be a string such as ``"database.html"``. Runtime template selection still happens in the view code, since most pages consider more specific template names before falling back to the canonical one.
-
-When a context field contains repeated structured data, prefer a small nested dataclass over an anonymous dictionary. For example, a field containing table summaries should be annotated as ``list[DatabaseTable]`` where ``DatabaseTable`` is a dataclass describing the keys and value types. This keeps the Python contract and generated documentation clear. JSON responses and ``?_context=1`` debug output will convert nested dataclasses back to JSON objects at the response boundary.

@@ -2032,30 +1743,7 @@ This method can be used to queue up a non-SELECT SQL query to be executed agains
 
 You can pass additional SQL parameters as a tuple or dictionary.
 
-The optional ``request=`` argument is used internally by Datasette to pass request context to :ref:`write_wrapper plugin hooks <plugin_hook_write_wrapper>`.
-
-The method will block until the operation is completed, and the return value will be an ``ExecuteWriteResult`` object. This imitates a subset of the ``sqlite3.Cursor`` object:
-
-``.rowcount``
-    The number of rows modified by the statement, or ``-1`` if that number is unavailable.
-
-``.lastrowid``
-    The row ID of the last modified row, as returned by ``sqlite3.Cursor.lastrowid``.
-
-``.description``
-    The same column metadata exposed by Python's `sqlite3.Cursor.description <https://docs.python.org/3/library/sqlite3.html#sqlite3.Cursor.description>`__: one tuple per returned column, or ``None`` if the statement does not return rows.
-
-``.truncated``
-    ``True`` if the statement returned more rows than ``returning_limit``.
-
-``.fetchall()``
-    Returns any rows buffered by Datasette from the statement, such as rows from SQLite's ``RETURNING`` clause. This may be limited by ``returning_limit`` unless ``return_all=True`` was used. This method empties the buffer, so calling it again will return an empty list.
-
-SQLite statements using ``RETURNING`` must have their rows consumed before the transaction can commit. Datasette will fetch up to ``returning_limit + 1`` rows before committing, store up to ``returning_limit`` rows on the result object and set ``.truncated`` if there were more. The default ``returning_limit`` is ``10``.
-
-When ``.truncated`` is ``True``, ``.rowcount`` will be ``-1``. SQLite only reports the final row count for a ``RETURNING`` statement after every returned row has been fetched, and Datasette has deliberately stopped fetching rows after ``returning_limit`` to avoid buffering a potentially large result in memory.
-
-If you need to retrieve every row returned by a statement, pass ``return_all=True``. This will buffer all returned rows in memory before committing.
+The method will block until the operation is completed, and the return value will be the return from calling ``conn.execute(...)`` using the underlying ``sqlite3`` Python library.
 
 If you pass ``block=False`` this behavior changes to "fire and forget" - queries will be added to the write queue and executed in a separate thread while your code can continue to do other things. The method will return a UUID representing the queued task.

-makeColumnField(context)
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-This method, if present, can provide a custom form field for a column in Datasette's row insert and edit dialogs.
-
-It is designed for plugins that :ref:`register custom column types <plugin_register_column_types>` using the Python ``register_column_types()`` plugin hook. For example, a plugin that defines a ``file`` column type can use ``makeColumnField()`` to replace a plain text input with a file picker, and a plugin that defines a rich text column type can use it to enhance the field with an editor.
-
-Datasette calls ``makeColumnField(context)`` on each registered JavaScript plugin when it renders an editable insert/edit field. Plugins should inspect the ``context`` object and only return a control object if they can handle that field. Otherwise, use a bare ``return;``.
-
-The first plugin to return a truthy control object is used for that field. Plugins are called in registration order. If a plugin raises an exception, Datasette logs the error to the browser console and continues to the next plugin.
-
-The row dialog tracks the value that will be sent to the insert/update API. The ``context`` object describes the column and form environment; custom controls should read and write field values using the ``field`` helper object passed to ``render(field)``.
-
-Context object
-^^^^^^^^^^^^^^
-
-``makeColumnField(context)`` is called with a context object describing the field. The current context object has these keys:
-
-``mode`` - string
-    ``"insert"`` or ``"edit"``.
-
-``database`` - string or null
-    The database name.
-
-``table`` - string or null
-    The table name.
-
-``tableUrl`` - string or null
-    The path to the table page, including any configured :ref:`base URL prefix <setting_base_url>`.
-
-``column`` - string
-    The column name.
-
-``columnType`` - object or null
-    The configured Datasette column type for this column, if one exists. This is ``null`` if no column type has been configured.
-
-    If present, this object has exactly these keys:
-
-    ``type`` - string
-        The :ref:`registered column type name <plugin_register_column_types>`, matching the ``name`` attribute of the Python ``ColumnType`` subclass.
-
-    ``config`` - object
-        Configuration for this specific column type assignment. This is ``{}`` if no configuration has been set.
-
-``sqliteType`` - string or null
-    The SQLite affinity for this column, if known. This is one of ``"TEXT"``, ``"INTEGER"``, ``"REAL"``, ``"BLOB"``, ``"NUMERIC"`` or ``null`` if Datasette could not determine the affinity.
-
-``notNull`` - boolean
-    True if the column is defined as ``NOT NULL``.
-
-``isPk`` - boolean
-    True if this column is part of the table's primary key.
-
-``defaultExpression`` - string or null
-    The SQLite default expression for the column, if available. This is ``null`` if the column has no SQLite default. For example, a column defined with ``DEFAULT (datetime('now'))`` will have ``"datetime('now')"`` here. This is the expression from the table schema, not the actual value SQLite will insert.
-
-``form`` - ``HTMLFormElement`` or null
-    The row insert/edit form element.
-
-``dialog`` - ``HTMLDialogElement`` or null
-    The modal dialog element.
-
-Returned control object
-^^^^^^^^^^^^^^^^^^^^^^^
-
-A plugin that wants to handle a field should return an object. Datasette currently recognizes these properties:
-
-``useTextarea`` - boolean, optional
-    If true, Datasette creates a ``<textarea>`` as the underlying ``field.input`` before calling ``render()``. If omitted, Datasette chooses either an ``<input>`` or ``<textarea>`` based on the column type and current value.
-
-``render(field)`` - function
-    Called once to render the custom field UI. ``field`` is a helper object described below.
-
-    The recommended pattern is to return a DOM node from ``render()``. Datasette appends that node to ``field.root``, a ``<div>`` inside the control area for that field in the row insert/edit dialog. A plugin can alternatively manipulate ``field.root`` directly and return nothing.
-
-``focus(field)`` - function, optional
-    Called when Datasette wants to focus this field, for example when focusing the first editable field in the dialog. Use this to focus the most useful interactive element inside the custom UI.
-
-``destroy(field)`` - function, optional
-    Called when Datasette tears down the insert/edit form. Use this to remove event listeners, close nested pickers, revoke object URLs, clear timers, or release other resources.
-
-The field helper object
-^^^^^^^^^^^^^^^^^^^^^^^
-
-The ``field`` object passed to ``render(field)``, ``focus(field)`` and ``destroy(field)`` provides stable IDs, DOM elements and value helpers for integrating with the row insert/edit dialog:
-
-``context`` - object
-    The original context object passed to ``makeColumnField()``.
-
-``id`` - string
-    The ID Datasette assigned to ``field.input``, the backing ``<input>`` or ``<textarea>`` element.
-
-``labelId`` - string
-    The ID of the visible field label.
-
-``descriptionId`` - string
-    The ID of the field metadata/help text. This metadata can include details such as ``Primary key``, ``Required``, ``Current value: NULL`` or ``Custom type: file``.
-
-``root`` - ``HTMLElement``
-    The empty ``<div>`` container created by Datasette for this custom field. It is inside the control area for the field in the row insert/edit dialog, next to the field label and above the field metadata. Datasette appends the DOM node returned by ``render(field)`` to this element. Plugins can alternatively manipulate this element directly and return nothing from ``render(field)``.
-
-``input`` - ``HTMLInputElement`` or ``HTMLTextAreaElement``
-    The core-owned backing form control. Plugins can keep this visible, wrap it or hide it, but should use the value helper methods below rather than mutating ``input.value`` directly.
-
-``control``
-    An alias for ``input``.
-
-``meta`` - ``HTMLElement`` or null
-    The field metadata/help text element.
-
-``form`` - ``HTMLFormElement`` or null
-    The containing row insert/edit form.
-
-``dialog`` - ``HTMLDialogElement`` or null
-    The containing modal dialog.
-
-``getValue()`` - function
-    Returns the current value for this field.
-
-    Datasette uses string values by default. Insert fields for ``"INTEGER"`` and ``"REAL"`` SQLite columns return numbers, or ``null`` if left blank. Plugins can use strings, numbers, booleans or ``null``. If a plugin is editing structured data stored in a SQLite ``TEXT`` column, such as JSON, it should serialize that data to a string before calling ``setValue()``.
-
-``setValue(value)`` - function
-    Sets the current value for this field. ``value`` should be a string, number, boolean or ``null``.
-
-    Calling ``setValue()`` also stops using the SQLite default for the field, if it was previously selected.
-
-``getInitialValue()`` - function
-    Returns the submitted-value representation the field had when the form was rendered. For edit forms this is the raw row value from the database. For insert forms this is the blank starting value.
-
-``hasChanged()`` - function
-    Returns true if the field has changed since Datasette last considered it unmodified. By default that means the field state when the insert/edit form was rendered.
-
-``clearValue()`` - function
-    Sets the value to ``null``.
-
-``markClean()`` - function
-    Tells Datasette to treat the field's current state as unmodified. After calling this method, ``hasChanged()`` returns false until the field value changes again or its SQLite-default state changes.
-
-    This is useful when a plugin rewrites the starting value into an equivalent representation while initializing its editor. For example, a rich text editor might normalize empty HTML or reserialize its initial document before the user has made any edits.
-
-``isUsingSqliteDefault()`` - function
-    Returns true if the insert dialog is currently set to omit this column and use the SQLite default.
-
-``setValidity(message)`` - function
-    Sets a custom validation message for this field, marks the backing input with ``aria-invalid="true"`` and shows the message in the field metadata area. Pass an empty string to clear the error.
-
-``clearValidity()`` - function
-    Clears any custom validation message previously set by ``setValidity()``.
-
-Submitted value contract
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-The ``field.setValue()`` method accepts the following value types:
-
-* string
-* number
-* boolean
-* ``null``
-
-These values are used as column values in requests to the :ref:`insert rows <TableInsertView>` and :ref:`update row <RowUpdateView>` JSON APIs.
-
-Plugins should not pass objects or arrays to ``field.setValue()``. If a column stores structured data in SQLite, such as JSON in a ``TEXT`` column, the plugin should serialize that data first and submit the serialized string. Client-side parsing can still be useful for validation or editor state, but the submitted value should match the SQLite value Datasette should write.
-
-Value helpers
-^^^^^^^^^^^^^
-
-Custom fields should use ``field.getValue()`` and ``field.setValue(value)`` for value handling:
-
-.. code-block:: javascript
-
-    const currentValue = field.getValue();
-    field.setValue("new value");
-    field.setValue(null);
-
-Plugins can keep the core input visible, wrap it in a custom element, or hide it and provide a richer interface. If the input is hidden, the custom UI must still expose an accessible name, state and keyboard interaction.
-
-``field.setValue()`` updates both ``field.input`` and the value used in the insert/update request.
-
-For example, a file picker that stores a selected file ID can hide the backing input and call ``field.setValue()`` when the selection changes:
-
-.. code-block:: javascript
-
-    field.input.type = "hidden";
-    field.setValue(fileId);
-
-For insert forms with a SQLite default, ``field.isUsingSqliteDefault()`` indicates whether Datasette will omit that column from the insert payload. Calling ``field.setValue(value)`` automatically stops using the SQLite default.
-
-Lazy loading large controls
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The JavaScript file that registers ``makeColumnField()`` should be small. If the actual control is large, load it from inside ``render()`` using dynamic ``import()``. That way the heavier code is only downloaded after a user opens an insert/edit dialog containing a matching column type.
-
-.. code-block:: javascript
-
-    const editorUrl = new URL("./editor.js", import.meta.url).href;
-
-    document.addEventListener("datasette_init", function (event) {
-      event.detail.registerPlugin("my-editor", {
-        version: "0.1",
-
-        makeColumnField(context) {
-          if (!context.columnType || context.columnType.type !== "my-editor") {
-            return;
-          }
-          return {
-            useTextarea: true,
-            render(field) {
-              import(editorUrl).then(function () {
-                // Enhance field.input here.
-              });
-              return field.input;
-            }
-          };
-        }
-      });
-    });
-
-Example: textarea-backed custom element
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-This example handles a ``markdown-editor`` column type by asking Datasette for a textarea and wrapping that textarea in a custom ``<my-markdown-editor>`` Web Component element:
-
-.. code-block:: javascript
-
-    document.addEventListener("datasette_init", function (event) {
-      event.detail.registerPlugin("markdown-editor", {
-        version: "0.1",
-
-        makeColumnField(context) {
-          if (!context.columnType || context.columnType.type !== "markdown-editor") {
-            return;
-          }
-
-          return {
-            useTextarea: true,
-
-            render(field) {
-              const editor = document.createElement("my-markdown-editor");
-              editor.appendChild(field.input);
-
-              if (field.labelId) {
-                field.input.setAttribute("aria-labelledby", field.labelId);
-              }
-              if (field.descriptionId) {
-                field.input.setAttribute("aria-describedby", field.descriptionId);
-              }
-
-              return editor;
-            },
-
-            focus(field) {
-              const editor = field.root.querySelector("my-markdown-editor");
-              if (editor && editor.focus) {
-                editor.focus();
-              } else {
-                field.input.focus();
-              }
-            }
-          };
-        }
-      });
-    });
-
-Accessibility
-^^^^^^^^^^^^^
-
-Custom fields are responsible for preserving the accessibility of the form:
-
-- The visible field label should name the control. Use ``field.labelId`` with ``aria-labelledby`` when wrapping or replacing the visible input.
-- Field metadata should remain available to assistive technology. Use ``field.descriptionId`` with ``aria-describedby``.
-- Keyboard users must be able to operate every part of the custom field.
-- If the field opens an inline picker or other nested UI, ``Escape`` should close that nested UI first and return focus to a sensible element.
-- If a control performs asynchronous loading, expose loading and error states in the UI. Use appropriate ARIA live regions where the state change is important to understand the field.
-- If a plugin hides ``field.input``, the replacement UI must still make the current value and available actions clear.
-
-Plugins should not submit the row themselves from inside ``makeColumnField()`` controls. Datasette owns the insert/edit dialog lifecycle, form submission, API call, error handling and row refresh.

-Stability means:

-  recognize.

-  :ref:`column filter operators <table_arguments>` are stable.
-- Pagination tokens - the ``"next"`` key and ``?_next=`` parameter - are
-  **opaque strings**. Pass them back exactly as you received them; their
-  internal structure is not part of the API and can change at any time.
-- The :ref:`standard error format <json_api_errors>` and the
-  :ref:`API token format and restriction semantics <CreateTokenView>` are
-  stable, including the action abbreviations stored inside signed tokens.
-
-Some JSON endpoints are **exempt** from this promise:

-Table autocomplete
-------------------
-
-The ``/<database>/<table>/-/autocomplete`` endpoint returns up to 10 primary key
-matches for a table, intended for building autocomplete interfaces such as
-foreign key pickers.
-
-::
-
-    GET /<database>/<table>/-/autocomplete?q=search
-
-The ``q`` parameter is required. If it is omitted or blank, the endpoint returns
-an empty ``"rows"`` list.
-
-The response includes a ``"pks"`` object containing the primary key value or
-values for each row. If Datasette can detect a label column, or one has been
-configured using ``label_column``, each row will also include ``"label"``:
-
-.. code-block:: json
-
-    {
-        "rows": [
-            {
-                "pks": {

-                "label": "Example row"
-            }
-        ]
-    }
-
-The endpoint searches the primary key column or columns and the label column
-using escaped SQL ``LIKE`` queries. A single-column primary key exact match is
-returned first. Other matches are ordered by the shortest matching label value
-where a label column is available.
-
-The initial search runs with a 500ms time limit. If that query times out,
-Datasette falls back to a prefix match against the first primary key column so
-SQLite can use the primary key index.

@@ -1657,116 +505,6 @@ The JSON write API
 
 Datasette provides a write API for JSON data. This is a POST-only API that requires an authenticated API token, see :ref:`CreateTokenView`. The token will need to have the specified :ref:`authentication_permissions`.
 
-The request body is always parsed as JSON, regardless of the request's ``Content-Type`` header - a body that is not valid JSON returns a ``400`` error. Cross-site request forgery is prevented by Datasette's ``Origin`` and ``Sec-Fetch-Site`` header checks rather than by content type requirements.
-
-The row-based write APIs can write :ref:`binary values in JSON <binary_json_format>` using Datasette's Base64 representation for BLOB data.
-
-.. _ExecuteWriteView:
-
-Executing write SQL
-~~~~~~~~~~~~~~~~~~~
-
-Actors with the :ref:`actions_execute_write_sql` permission can execute arbitrary writable SQL against a mutable database using ``/-/execute-write``.
-
-::
-
-    POST /<database>/-/execute-write
-    Content-Type: application/json
-    Authorization: Bearer dstok_<rest-of-token>
-
-The request body must include a ``"sql"`` string. Named SQL parameters can be provided using the optional ``"params"`` object:
-
-.. code-block:: json
-
-    {
-        "sql": "insert into dogs (name) values (:name)",
-        "params": {
-            "name": "Cleo"
-        }
-    }
-
-The SQL must be writable. Read-only ``select`` queries should use the regular :ref:`custom SQL query JSON API <json_api_custom_sql>` instead.
-
-Datasette analyzes the SQL before executing it. The actor must have ``execute-write-sql`` permission for the database, and must also have any permissions required by the operations in the SQL. For example, inserts and updates against a table require ``insert-row``, ``update-row`` and ``delete-row`` permissions for that table. Reads performed as part of the write, such as ``insert into dogs select ... from other_table``, require ``view-table`` permission on the source table. Schema changes require ``create-table``, ``alter-table`` or ``drop-table`` permissions as appropriate.
-
-Unsupported SQL operations are rejected by default. ``VACUUM`` is not allowed in arbitrary write SQL, and writes to SQLite virtual tables or shadow tables are rejected. SQL functions are allowed and are not separately restricted by Datasette permissions.
-
-A successful response includes a message, the SQLite ``rowcount``, a ``"rows"``
-list, a ``"truncated"`` flag and a summary of the operations that were executed:
-
-The shape of the ``"analysis"`` block is not part of the :ref:`stable API <json_api_stability>` and may change in future Datasette releases.

-Supported operations:
-
-* ``add_column`` adds a new column. ``args`` accepts ``name``, optional ``type`` of ``text``, ``integer``, ``float`` or ``blob``, optional ``not_null``, optional literal ``default`` and optional ``default_expr``. If ``not_null`` is ``true`` either a non-null ``default`` or ``default_expr`` is required.
-* ``rename_column`` renames a column. ``args`` accepts ``name`` and ``to``.
-* ``rename_table`` renames the table. ``args`` accepts ``to``, the new table name. If combined with other operations, Datasette applies the column, primary key, foreign key and column order changes before renaming the table.
-* ``alter_column`` changes column properties. ``args`` accepts ``name`` and at least one of ``type``, ``not_null``, literal ``default`` or ``default_expr``. Passing ``"default": null`` removes an existing default.
-* ``drop_column`` drops a column. ``args`` accepts ``name``.
-* ``set_primary_key`` changes the table primary key. ``args`` accepts ``columns``, a list of one or more column names.
-* ``add_foreign_key`` adds a single-column foreign key constraint. ``args`` accepts ``column``, ``fk_table`` and optional ``fk_column``. If ``fk_column`` is omitted, Datasette will use the single primary key of ``fk_table``.
-* ``drop_foreign_key`` removes the foreign key constraint for a column. ``args`` accepts ``column``.
-* ``set_foreign_keys`` replaces all foreign key constraints on the table. ``args`` accepts ``foreign_keys``, a list of objects that each have ``column``, ``fk_table`` and optional ``fk_column``. An empty list removes all foreign key constraints.
-* ``reorder_columns`` reorders columns. ``args`` accepts ``columns``, a list of one or more column names. Columns omitted from this list will appear afterwards in their existing order.
-
-``default`` is always treated as a literal value. ``default_expr`` accepts the values shown in :ref:`default_expr values <json_api_default_expr_values>` and is rendered as the corresponding SQLite default expression.
-
-For foreign key operations that omit ``fk_column``, the referenced ``fk_table`` must have a single-column primary key. Datasette will return an error if it cannot identify a single primary key column for that table.
-
-A successful response returns the new schema and the previous schema. If the request used ``rename_table``, ``table``, ``table_url`` and ``table_api_url`` will use the new table name. Renaming a table through this endpoint triggers the :class:`~datasette.events.RenameTableEvent` event.

-Stored queries
-~~~~~~~~~~~~~~
+Canned query parameters
+~~~~~~~~~~~~~~~~~~~~~~~
 
-Datasette stores both configured queries and user-created queries in the ``queries`` table in the :ref:`internal database <internals_internal>`. Configured queries come from the ``queries`` section of ``datasette.yaml``. User-created stored queries can be created from the SQL query page by actors with the :ref:`actions_store_query` and :ref:`actions_execute_sql` permissions. Writable stored queries also require the permissions needed for the writes they perform.
+Canned queries support named parameters, so if you include those in the SQL you will then be able to enter them using the form fields on the canned query page or by adding them to the URL. This means canned queries can be used to create custom JSON APIs based on a carefully designed SQL statement.
 
-Stored queries created by users default to private. Private stored queries can only be viewed, updated or deleted by the actor that created them. Broad ``view-query``, ``update-query`` or ``delete-query`` permission grants still do not allow other actors to access another actor's private stored queries.
-
-Editing and deleting stored queries
-+++++++++++++++++++++++++++++++++++
-
-The page for a stored query includes a "Query actions" menu with **Edit this query** and **Delete this query** links for actors who have permission to use them.
-
-The owner of a stored query can always edit and delete it. For queries that are not private, any actor granted the ``update-query`` or ``delete-query`` permission can edit or delete the query, even if they did not create it. Private queries can only be edited or deleted by their owner, regardless of any broad permission grants.
-
-Editing a query lets you change its title, description, SQL and whether it is private. Changing the SQL also requires the ``execute-sql`` permission (and the relevant write permissions for writable queries). The same operations are available through the JSON API by sending a ``POST`` to ``/<database>/<query>/-/update`` or ``/<database>/<query>/-/delete``. Trusted stored queries cannot be edited or deleted through the web interface or the JSON API.
-
-Stored queries created by users are untrusted. This means they execute using the permissions of the actor who runs them, as if that actor had pasted the SQL into the regular custom SQL interface or write SQL interface. Read-only stored queries require ``execute-sql``. Writable stored queries require ``execute-write-sql`` plus the relevant table-level write permissions. SQL functions are allowed and are not separately restricted by Datasette permissions.

-Trusted stored queries
-++++++++++++++++++++++
-
-A trusted stored query can execute with ``view-query`` permission alone. It skips the additional ``execute-sql`` and write permission checks that are applied to untrusted stored queries.
-
-Trusted stored queries should only be used for SQL that has been reviewed by someone trusted to configure the Datasette instance. For that reason, trusted stored queries can only be added using configuration. Users cannot create trusted stored queries through the web interface or the stored query JSON API.
-
