Update Django from 4.2.1 to 5.1.

Changelog ### 5.1 ``` ======================== *August 7, 2024* Welcome to Django 5.1! These release notes cover the :ref:`new features <whats-new-5.1>`, as well as some :ref:`backwards incompatible changes <backwards-incompatible-5.1>` you should be aware of when upgrading from Django 5.0 or earlier. We've :ref:`begun the deprecation process for some features <deprecated-features-5.1>`. See the :doc:`/howto/upgrade-version` guide if you're updating an existing project. Python compatibility ==================== Django 5.1 supports Python 3.10, 3.11, and 3.12. We **highly recommend** and only officially support the latest release of each series. .. _whats-new-5.1: What's new in Django 5.1 ======================== ``{% querystring %}`` template tag ----------------------------------- Django 5.1 introduces the :ttag:`{% querystring %} <querystring>` template tag, simplifying the modification of query parameters in URLs, making it easier to generate links that maintain existing query parameters while adding or changing specific ones. For instance, navigating pagination and query strings in templates can be cumbersome. Consider this template fragment that dynamically generates a URL for navigating to the next page within a paginated view: .. code-block:: html+django { Linebreaks added for readability, this should be one, long line. } <a href="?{% for key, values in request.GET.iterlists %} {% if key != "page" %} {% for value in values %} {{ key }}={{ value }}&amp; {% endfor %} {% endif %} {% endfor %}page={{ page.next_page_number }}">Next page</a> When switching to using this new template tag, the above magically becomes: .. code-block:: html+django <a href="{% querystring page=page.next_page_number %}">Next page</a> PostgreSQL Connection Pools --------------------------- Django 5.1 also introduces :ref:`connection pool <postgresql-pool>` support for PostgreSQL. As the time to establish a new connection can be relatively long, keeping connections open can reduce latency. To use a connection pool with `psycopg`_, you can set the ``"pool"`` option inside :setting:`OPTIONS` to be a dict to be passed to :class:`~psycopg:psycopg_pool.ConnectionPool`, or to ``True`` to use the ``ConnectionPool`` defaults:: DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", ... "OPTIONS": { "pool": { "min_size": 2, "max_size": 4, "timeout": 10, } }, }, } .. _psycopg: https://www.psycopg.org/ Middleware to require authentication by default ----------------------------------------------- The new :class:`~django.contrib.auth.middleware.LoginRequiredMiddleware` redirects all unauthenticated requests to a login page. Views can allow unauthenticated requests by using the new :func:`~django.contrib.auth.decorators.login_not_required` decorator. The :class:`~django.contrib.auth.middleware.LoginRequiredMiddleware` respects the ``login_url`` and ``redirect_field_name`` values set via the :func:`~.django.contrib.auth.decorators.login_required` decorator, but does not support setting ``login_url`` or ``redirect_field_name`` via the :class:`~django.contrib.auth.mixins.LoginRequiredMixin`. Minor features -------------- :mod:`django.contrib.admin` ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * :attr:`.ModelAdmin.list_display` now supports using ``__`` lookups to list fields from related models. :mod:`django.contrib.auth` ~~~~~~~~~~~~~~~~~~~~~~~~~~ * The default iteration count for the PBKDF2 password hasher is increased from 720,000 to 870,000. * The default ``parallelism`` of the ``ScryptPasswordHasher`` is increased from 1 to 5, to follow OWASP recommendations. * :class:`~django.contrib.auth.forms.BaseUserCreationForm` and :class:`~django.contrib.auth.forms.AdminPasswordChangeForm` now support disabling password-based authentication by setting an unusable password on form save. This is now available in the admin when visiting the user creation and password change pages. * :func:`~.django.contrib.auth.decorators.login_required`, :func:`~.django.contrib.auth.decorators.permission_required`, and :func:`~.django.contrib.auth.decorators.user_passes_test` decorators now support wrapping asynchronous view functions. * ``ReadOnlyPasswordHashWidget`` now includes a button to reset the user's password, which replaces the link previously embedded in the ``ReadOnlyPasswordHashField``'s help text, improving the overall accessibility of the :class:`~django.contrib.auth.forms.UserChangeForm`. :mod:`django.contrib.gis` ~~~~~~~~~~~~~~~~~~~~~~~~~ * :class:`~django.contrib.gis.db.models.functions.BoundingCircle` is now supported on SpatiaLite 5.1+. * :class:`~django.contrib.gis.db.models.Collect` is now supported on MySQL 8.0.24+. * :class:`~django.contrib.gis.geoip2.GeoIP2` now allows querying using :class:`ipaddress.IPv4Address` or :class:`ipaddress.IPv6Address` objects. * :meth:`.GeoIP2.country` now exposes the ``continent_code``, ``continent_name``, and ``is_in_european_union`` values. * :meth:`.GeoIP2.city` now exposes the ``accuracy_radius`` and ``region_name`` values. In addition, the ``dma_code`` and ``region`` values are now exposed as ``metro_code`` and ``region_code``, but the previous keys are also retained for backward compatibility. * :class:`~django.contrib.gis.measure.Area` now supports the ``ha`` unit. * The new :attr:`.OGRGeometry.is_3d` attribute allows checking if a geometry has a ``Z`` coordinate dimension. * The new :meth:`.OGRGeometry.set_3d` method allows addition and removal of the ``Z`` coordinate dimension. * :class:`~django.contrib.gis.gdal.OGRGeometry`, :class:`~django.contrib.gis.gdal.Point`, :class:`~django.contrib.gis.gdal.LineString`, :class:`~django.contrib.gis.gdal.Polygon`, and :class:`~django.contrib.gis.gdal.GeometryCollection` and its subclasses now support measured geometries via the new :attr:`.OGRGeometry.is_measured` and ``m`` properties, and the :meth:`.OGRGeometry.set_measured` method. * :attr:`.OGRGeometry.centroid` is now available on all supported geometry types. * :class:`FromWKB() <django.contrib.gis.db.models.functions.FromWKB>` and :class:`FromWKT() <django.contrib.gis.db.models.functions.FromWKT>` functions now support the optional ``srid`` argument (except for Oracle where it is ignored). :mod:`django.contrib.postgres` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * :class:`~django.contrib.postgres.indexes.BTreeIndex` now supports the ``deduplicate_items`` parameter. :mod:`django.contrib.sessions` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * :class:`django.contrib.sessions.backends.cached_db.SessionStore` now handles exceptions when storing session information in the cache, logging proper error messages with their traceback via the newly added :ref:`sessions logger <django-contrib-sessions-logger>`. * :class:`django.contrib.sessions.backends.base.SessionBase` and all built-in session engines now provide async API. The new asynchronous methods all have ``a`` prefixed names, e.g. ``aget()``, ``akeys()``, or ``acycle_key()``. Database backends ~~~~~~~~~~~~~~~~~ * ``"init_command"`` option is now supported in :setting:`OPTIONS` on SQLite to allow specifying :ref:`pragma options <sqlite-init-command>` to set upon connection. * ``"transaction_mode"`` option is now supported in :setting:`OPTIONS` on SQLite to allow specifying the :ref:`sqlite-transaction-behavior`. * ``"pool"`` option is now supported in :setting:`OPTIONS` on PostgreSQL to allow using :ref:`connection pools <postgresql-pool>`. Error Reporting ~~~~~~~~~~~~~~~ * In order to improve accessibility, the technical 404 and 500 error pages now use HTML landmark elements for the header, footer, and main content areas. File Storage ~~~~~~~~~~~~ * The :attr:`~django.core.files.storage.FileSystemStorage.allow_overwrite` parameter of :class:`~django.core.files.storage.FileSystemStorage` now allows saving new files over existing ones. Forms ~~~~~ * In order to improve accessibility and enable screen readers to associate fieldsets with their help text, the form fieldset now includes the ``aria-describedby`` HTML attribute. Management Commands ~~~~~~~~~~~~~~~~~~~ * The :djadmin:`makemigrations` command now displays meaningful symbols for each operation to highlight :class:`operation categories <django.db.migrations.operations.base.OperationCategory>`. Migrations ~~~~~~~~~~ * The new ``Operation.category`` attribute allows specifying an :class:`operation category <django.db.migrations.operations.base.OperationCategory>` used by the :djadmin:`makemigrations` to display a meaningful symbol for the operation. Models ~~~~~~ * :meth:`.QuerySet.explain` now supports the ``generic_plan`` option on PostgreSQL 16+. * :class:`~django.db.models.expressions.RowRange` now accepts positive integers for the ``start`` argument and negative integers for the ``end`` argument. * The new ``exclusion`` argument of :class:`~django.db.models.expressions.RowRange` and :class:`~django.db.models.expressions.ValueRange` allows excluding rows, groups, and ties from the window frames. * :meth:`.QuerySet.order_by` now supports ordering by annotation transforms such as ``JSONObject`` keys and ``ArrayAgg`` indices. * :class:`F() <django.db.models.F>` and :class:`OuterRef() <django.db.models.OuterRef>` expressions that output :class:`~django.db.models.CharField`, :class:`~django.db.models.EmailField`, :class:`~django.db.models.SlugField`, :class:`~django.db.models.URLField`, :class:`~django.db.models.TextField`, or :class:`~django.contrib.postgres.fields.ArrayField` can now be :ref:`sliced <slicing-using-f>`. * The new ``from_queryset`` argument of :meth:`.Model.refresh_from_db` and :meth:`.Model.arefresh_from_db` allows customizing the queryset used to reload a model's value. This can be used to lock the row before reloading or to select related objects. * The new :attr:`.Expression.constraint_validation_compatible` attribute allows specifying that the expression should be ignored during a constraint validation. Templates ~~~~~~~~~ * Custom tags may now set extra data on the ``Parser`` object that will later be made available on the ``Template`` instance. Such data may be used, for example, by the template loader, or other template clients. * :ref:`Template engines <field-checking>` now implement a ``check()`` method that is already registered with the check framework. Tests ~~~~~ * :meth:`~django.test.SimpleTestCase.assertContains`, :meth:`~django.test.SimpleTestCase.assertNotContains`, and :meth:`~django.test.SimpleTestCase.assertInHTML` assertions now add haystacks to assertion error messages. * The :class:`~django.test.RequestFactory`, :class:`~django.test.AsyncRequestFactory`, :class:`~django.test.Client`, and :class:`~django.test.AsyncClient` classes now support the ``query_params`` parameter, which accepts a dictionary of query string keys and values. This allows setting query strings on any HTTP methods more easily. .. code-block:: python self.client.post("/items/1", query_params={"action": "delete"}) await self.async_client.post("/items/1", query_params={"action": "delete"}) * The new :meth:`.SimpleTestCase.assertNotInHTML` assertion allows testing that an HTML fragment is not contained in the given HTML haystack. * In order to enforce test isolation, database connections inside threads are no longer allowed in :class:`~django.test.SimpleTestCase`. Validators ~~~~~~~~~~ * The new :class:`~django.core.validators.DomainNameValidator` validates domain names, including internationalized domain names. The new :func:`~django.core.validators.validate_domain_name` function returns an instance of :class:`~django.core.validators.DomainNameValidator`. .. _backwards-incompatible-5.1: Backwards incompatible changes in 5.1 ===================================== :mod:`django.contrib.gis` ------------------------- * Support for PostGIS 2.5 is removed. * Support for PROJ < 6 is removed. * Support for GDAL 2.4 is removed. * :class:`~django.contrib.gis.geoip2.GeoIP2` no longer opens both city and country databases when a directory path is provided, preferring the city database, if it is available. The country database is a subset of the city database and both are not typically needed. If you require use of the country database when in the same directory as the city database, explicitly pass the country database path to the constructor. Dropped support for MariaDB 10.4 -------------------------------- Upstream support for MariaDB 10.4 ends in June 2024. Django 5.1 supports MariaDB 10.5 and higher. Dropped support for PostgreSQL 12 --------------------------------- Upstream support for PostgreSQL 12 ends in November 2024. Django 5.1 supports PostgreSQL 13 and higher. Miscellaneous ------------- * In order to improve accessibility, the admin's changelist filter is now rendered in a ``<nav>`` tag instead of a ``<div>``. * In order to improve accessibility, the admin's footer is now rendered in a ``<footer>`` tag instead of a ``<div>``, and also moved below the ``<div id="main">`` element. * In order to improve accessibility, the expandable widget used for :attr:`ModelAdmin.fieldsets <django.contrib.admin.ModelAdmin.fieldsets>` and :attr:`InlineModelAdmin.fieldsets <django.contrib.admin.InlineModelAdmin>`, when the fieldset has a name and use the ``collapse`` class, now includes ``<details>`` and ``<summary>`` elements. * The JavaScript file ``collapse.js`` is removed since it is no longer needed in the Django admin site. * :meth:`.SimpleTestCase.assertURLEqual` and :meth:`~django.test.SimpleTestCase.assertInHTML` now add ``": "`` to the ``msg_prefix``. This is consistent with the behavior of other assertions. * ``django.utils.text.Truncator`` used by :tfilter:`truncatechars_html` and :tfilter:`truncatewords_html` template filters now uses :py:class:`html.parser.HTMLParser` subclasses. This results in a more robust and faster operation, but there may be small differences in the output. * The undocumented ``django.urls.converters.get_converter()`` function is removed. * The minimum supported version of SQLite is increased from 3.27.0 to 3.31.0. * :class:`~django.db.models.FileField` now raises a :class:`~django.core.exceptions.FieldError` when saving a file without a ``name``. * ``ImageField.update_dimension_fields(force=True)`` is no longer called after saving the image to storage. If your storage backend resizes images, the ``width_field`` and ``height_field`` will not match the width and height of the image. * The minimum supported version of ``asgiref`` is increased from 3.7.0 to 3.8.1. .. _deprecated-features-5.1: Features deprecated in 5.1 ========================== Miscellaneous ------------- * The ``ModelAdmin.log_deletion()`` and ``LogEntryManager.log_action()`` methods are deprecated. Subclasses should implement ``ModelAdmin.log_deletions()`` and ``LogEntryManager.log_actions()`` instead. * The undocumented ``django.utils.itercompat.is_iterable()`` function and the ``django.utils.itercompat`` module are deprecated. Use ``isinstance(..., collections.abc.Iterable)`` instead. * The ``django.contrib.gis.geoip2.GeoIP2.coords()`` method is deprecated. Use ``django.contrib.gis.geoip2.GeoIP2.lon_lat()`` instead. * The ``django.contrib.gis.geoip2.GeoIP2.open()`` method is deprecated. Use the :class:`~django.contrib.gis.geoip2.GeoIP2` constructor instead. * Passing positional arguments to :meth:`.Model.save` and :meth:`.Model.asave` is deprecated in favor of keyword-only arguments. * Setting ``django.contrib.gis.gdal.OGRGeometry.coord_dim`` is deprecated. Use :meth:`~django.contrib.gis.gdal.OGRGeometry.set_3d` instead. * Overriding existing converters with ``django.urls.register_converter()`` is deprecated. * The ``check`` keyword argument of ``CheckConstraint`` is deprecated in favor of ``condition``. * The undocumented ``OS_OPEN_FLAGS`` property of :class:`~django.core.files.storage.FileSystemStorage` is deprecated. To allow overwriting files in storage, set the new :attr:`~django.core.files.storage.FileSystemStorage.allow_overwrite` option to ``True`` instead. * The ``get_cache_name()`` method of ``FieldCacheMixin`` is deprecated in favor of the ``cache_name`` cached property. Features removed in 5.1 ======================= These features have reached the end of their deprecation cycle and are removed in Django 5.1. See :ref:`deprecated-features-4.2` for details on these changes, including how to remove usage of these features. * The ``BaseUserManager.make_random_password()`` method is removed. * The model's ``Meta.index_together`` option is removed. * The ``length_is`` template filter is removed. * The ``django.contrib.auth.hashers.SHA1PasswordHasher``, ``django.contrib.auth.hashers.UnsaltedSHA1PasswordHasher``, and ``django.contrib.auth.hashers.UnsaltedMD5PasswordHasher`` are removed. * The model ``django.contrib.postgres.fields.CICharField``, ``django.contrib.postgres.fields.CIEmailField``, and ``django.contrib.postgres.fields.CITextField`` are removed, except for support in historical migrations. * The ``django.contrib.postgres.fields.CIText`` mixin is removed. * The ``map_width`` and ``map_height`` attributes of ``BaseGeometryWidget`` are removed. * The ``SimpleTestCase.assertFormsetError()`` method is removed. * The ``TransactionTestCase.assertQuerysetEqual()`` method is removed. * Support for passing encoded JSON string literals to ``JSONField`` and associated lookups and expressions is removed. * Support for passing positional arguments to ``Signer`` and ``TimestampSigner`` is removed. * The ``DEFAULT_FILE_STORAGE`` and ``STATICFILES_STORAGE`` settings is removed. * The ``django.core.files.storage.get_storage_class()`` function is removed. ========================== ``` ### 5.0.8 ``` ========================== *August 6, 2024* Django 5.0.8 fixes three security issues with severity "moderate", one security issue with severity "high", and several bugs in 5.0.7.

CVE-2024-39330: Potential directory-traversal via ``Storage.save()`` ==================================================================== Derived classes of the :class:`~django.core.files.storage.Storage` base class which override :meth:`generate_filename() <django.core.files.storage.Storage.generate_filename()>` without replicating the file path validations existing in the parent class, allowed for potential directory-traversal via certain inputs when calling :meth:`save() <django.core.files.storage.Storage.save()>`. Built-in ``Storage`` sub-classes were not affected by this vulnerability. CVE-2024-39614: Potential denial-of-service vulnerability in ``get_supported_language_variant()`` ================================================================================================= :meth:`~django.utils.translation.get_supported_language_variant` was subject to a potential denial-of-service attack when used with very long strings containing specific characters.

Bugfixes ======== * Reallowed, following a regression in Django 5.0, using a foreign key to a model with a primary key that is not ``AutoField`` in :attr:`.ModelAdmin.list_filter` (:ticket:`35020`). * Fixed a long standing bug in handling the ``RETURNING INTO`` clause that caused a crash when creating a model instance with a ``GeneratedField`` which ``output_field`` had backend-specific converters (:ticket:`35024`). * Fixed a regression in Django 5.0 that caused a crash of ``Model.save()`` for models with both ``GeneratedField`` and ``ForeignKey`` fields (:ticket:`35019`). * Fixed a bug in Django 5.0 that caused a migration crash on Oracle < 23c when adding a ``GeneratedField`` with ``output_field=BooleanField`` (:ticket:`35018`). * Fixed a regression in Django 5.0 where admin fields on the same line could overflow the page and become non-interactive (:ticket:`35012`). * Added compatibility for ``oracledb`` 2.0.0 (:ticket:`35054`). * Fixed a regression in Django 5.0 where querysets referenced incorrect field names from ``FilteredRelation()`` (:ticket:`35050`). * Fixed a regression in Django 5.0 that caused a system check crash when ``ModelAdmin.filter_horizontal`` or ``filter_vertical`` contained a reverse many-to-many relation with ``related_name`` (:ticket:`35056`). ======================== ``` ### 5.0 ``` ======================== *December 4, 2023* Welcome to Django 5.0! These release notes cover the :ref:`new features <whats-new-5.0>`, as well as some :ref:`backwards incompatible changes <backwards-incompatible-5.0>` you'll want to be aware of when upgrading from Django 4.2 or earlier. We've :ref:`begun the deprecation process for some features <deprecated-features-5.0>`. See the :doc:`/howto/upgrade-version` guide if you're updating an existing project. Python compatibility ==================== Django 5.0 supports Python 3.10, 3.11, and 3.12. We **highly recommend** and only officially support the latest release of each series. The Django 4.2.x series is the last to support Python 3.8 and 3.9. Third-party library support for older version of Django ======================================================= Following the release of Django 5.0, we suggest that third-party app authors drop support for all versions of Django prior to 4.2. At that time, you should be able to run your package's tests using ``python -Wd`` so that deprecation warnings appear. After making the deprecation warning fixes, your app should be compatible with Django 5.0. .. _whats-new-5.0: What's new in Django 5.0 ======================== Facet filters in the admin -------------------------- Facet counts are now shown for applied filters in the admin changelist when toggled on via the UI. This behavior can be changed via the new :attr:`.ModelAdmin.show_facets` attribute. For more information see :ref:`facet-filters`. Simplified templates for form field rendering --------------------------------------------- Django 5.0 introduces the concept of a field group, and field group templates. This simplifies rendering of the related elements of a Django form field such as its label, widget, help text, and errors. For example, the template below: .. code-block:: html+django <form> ... <div> {{ form.name.label_tag }} {% if form.name.help_text %} <div class="helptext" id="{{ form.name.auto_id }}_helptext"> {{ form.name.help_text|safe }} </div> {% endif %} {{ form.name.errors }} {{ form.name }} <div class="row"> <div class="col"> {{ form.email.label_tag }} {% if form.email.help_text %} <div class="helptext" id="{{ form.email.auto_id }}_helptext"> {{ form.email.help_text|safe }} </div> {% endif %} {{ form.email.errors }} {{ form.email }} </div> <div class="col"> {{ form.password.label_tag }} {% if form.password.help_text %} <div class="helptext" id="{{ form.password.auto_id }}_helptext"> {{ form.password.help_text|safe }} </div> {% endif %} {{ form.password.errors }} {{ form.password }} </div> </div> </div> ... </form> Can now be simplified to: .. code-block:: html+django <form> ... <div> {{ form.name.as_field_group }} <div class="row"> <div class="col">{{ form.email.as_field_group }}</div> <div class="col">{{ form.password.as_field_group }}</div> </div> </div> ... </form> :meth:`~django.forms.BoundField.as_field_group` renders fields with the ``"django/forms/field.html"`` template by default and can be customized on a per-project, per-field, or per-request basis. See :ref:`reusable-field-group-templates`. Database-computed default values -------------------------------- The new :attr:`Field.db_default <django.db.models.Field.db_default>` parameter sets a database-computed default value. For example:: from django.db import models from django.db.models.functions import Now, Pi class MyModel(models.Model): age = models.IntegerField(db_default=18) created = models.DateTimeField(db_default=Now()) circumference = models.FloatField(db_default=2 * Pi()) Database generated model field ------------------------------ The new :class:`~django.db.models.GeneratedField` allows creation of database generated columns. This field can be used on all supported database backends to create a field that is always computed from other fields. For example:: from django.db import models from django.db.models import F class Square(models.Model): side = models.IntegerField() area = models.GeneratedField( expression=F("side") * F("side"), output_field=models.BigIntegerField(), db_persist=True, ) More options for declaring field choices ---------------------------------------- :attr:`.Field.choices` *(for model fields)* and :attr:`.ChoiceField.choices` *(for form fields)* allow for more flexibility when declaring their values. In previous versions of Django, ``choices`` should either be a list of 2-tuples, or an :ref:`field-choices-enum-types` subclass, but the latter required accessing the ``.choices`` attribute to provide the values in the expected form:: from django.db import models Medal = models.TextChoices("Medal", "GOLD SILVER BRONZE") SPORT_CHOICES = [ ("Martial Arts", [("judo", "Judo"), ("karate", "Karate")]), ("Racket", [("badminton", "Badminton"), ("tennis", "Tennis")]), ("unknown", "Unknown"), ] class Winner(models.Model): name = models.CharField(...) medal = models.CharField(..., choices=Medal.choices) sport = models.CharField(..., choices=SPORT_CHOICES) Django 5.0 adds support for accepting a mapping or a callable instead of an iterable, and also no longer requires ``.choices`` to be used directly to expand :ref:`enumeration types <field-choices-enum-types>`:: from django.db import models Medal = models.TextChoices("Medal", "GOLD SILVER BRONZE") SPORT_CHOICES = { Using a mapping instead of a list of 2-tuples. "Martial Arts": {"judo": "Judo", "karate": "Karate"}, "Racket": {"badminton": "Badminton", "tennis": "Tennis"}, "unknown": "Unknown", } def get_scores(): return [(i, str(i)) for i in range(10)] class Winner(models.Model): name = models.CharField(...) medal = models.CharField(..., choices=Medal) Using `.choices` not required. sport = models.CharField(..., choices=SPORT_CHOICES) score = models.IntegerField(choices=get_scores) A callable is allowed. Under the hood the provided ``choices`` are normalized into a list of 2-tuples as the canonical form whenever the ``choices`` value is updated. For more information, please check the :ref:`model field reference on choices <field-choices>`.

See the migration guide above for more details on :ref:`migrating-uuidfield`. * Django now supports `oracledb`_ version 1.3.2 or higher. Support for ``cx_Oracle`` is deprecated as of this release and will be removed in Django 6.0. Pagination ~~~~~~~~~~ * The new :attr:`django.core.paginator.Paginator.error_messages` argument allows customizing the error messages raised by :meth:`.Paginator.page`.

Validators ~~~~~~~~~~ * The new ``offset`` argument of :class:`~django.core.validators.StepValueValidator` allows specifying an offset for valid values. .. _backwards-incompatible-5.0: Backwards incompatible changes in 5.0 ===================================== Database backend API -------------------- This section describes changes that may be needed in third-party database backends. * ``DatabaseFeatures.supports_expression_defaults`` should be set to ``False`` if the database doesn't support using database functions as defaults. * ``DatabaseFeatures.supports_default_keyword_in_insert`` should be set to ``False`` if the database doesn't support the ``DEFAULT`` keyword in ``INSERT`` queries. * ``DatabaseFeatures.supports_default_keyword_in_bulk_insert`` should be set to ``False`` if the database doesn't support the ``DEFAULT`` keyword in bulk ``INSERT`` queries. :mod:`django.contrib.gis` ------------------------- * Support for GDAL 2.2 and 2.3 is removed. * Support for GEOS 3.6 and 3.7 is removed. :mod:`django.contrib.sitemaps` ------------------------------ * The ``django.contrib.sitemaps.ping_google()`` function and the ``ping_google`` management command are removed as the Google Sitemaps ping endpoint is deprecated and will be removed in January 2024. * The ``django.contrib.sitemaps.SitemapNotFound`` exception class is removed. Dropped support for MySQL < 8.0.11 ---------------------------------- Support for pre-releases of MySQL 8.0.x series is removed. Django 5.0 supports MySQL 8.0.11 and higher. Using ``create_defaults__exact`` may now be required with ``QuerySet.update_or_create()`` ----------------------------------------------------------------------------------------- :meth:`.QuerySet.update_or_create` now supports the parameter ``create_defaults``. As a consequence, any models that have a field named ``create_defaults`` that are used with an ``update_or_create()`` should specify the field in the lookup with ``create_defaults__exact``. .. _migrating-uuidfield: Migrating existing ``UUIDField`` on MariaDB 10.7+ ------------------------------------------------- On MariaDB 10.7+, ``UUIDField`` is now created as ``UUID`` column rather than ``CHAR(32)`` column. As a consequence, any ``UUIDField`` created in Django < 5.0 should be replaced with a ``UUIDField`` subclass backed by ``CHAR(32)``:: class Char32UUIDField(models.UUIDField): def db_type(self, connection): return "char(32)" def get_db_prep_value(self, value, connection, prepared=False): value = super().get_db_prep_value(value, connection, prepared) if value is not None: value = value.hex return value For example:: class MyModel(models.Model): uuid = models.UUIDField(primary_key=True, default=uuid.uuid4) Should become:: class Char32UUIDField(models.UUIDField): ... class MyModel(models.Model): uuid = Char32UUIDField(primary_key=True, default=uuid.uuid4) Running the :djadmin:`makemigrations` command will generate a migration containing a no-op ``AlterField`` operation. Miscellaneous ------------- * The ``instance`` argument of the undocumented ``BaseModelFormSet.save_existing()`` method is renamed to ``obj``. * The undocumented ``django.contrib.admin.helpers.checkbox`` is removed. * Integer fields are now validated as 64-bit integers on SQLite to match the behavior of ``sqlite3``. * The undocumented ``Query.annotation_select_mask`` attribute is changed from a set of strings to an ordered list of strings. * ``ImageField.update_dimension_fields()`` is no longer called on the ``post_init`` signal if ``width_field`` and ``height_field`` are not set. * :class:`~django.db.models.functions.Now` database function now uses ``LOCALTIMESTAMP`` instead of ``CURRENT_TIMESTAMP`` on Oracle. * :attr:`.AdminSite.site_header` is now rendered in a ``<div>`` tag instead of ``<h1>``. Screen reader users rely on heading elements for navigation within a page. Having two ``<h1>`` elements was confusing and the site header wasn't helpful as it is repeated on all pages. * In order to improve accessibility, the admin's main content area and header content area are now rendered in a ``<main>`` and ``<header>`` tag instead of ``<div>``. * On databases without native support for the SQL ``XOR`` operator, ``^`` as the exclusive or (``XOR``) operator now returns rows that are matched by an odd number of operands rather than exactly one operand. This is consistent with the behavior of MySQL, MariaDB, and Python. * The minimum supported version of ``asgiref`` is increased from 3.6.0 to 3.7.0. * The minimum supported version of ``selenium`` is increased from 3.8.0 to 4.8.0. * The ``AlreadyRegistered`` and ``NotRegistered`` exceptions are moved from ``django.contrib.admin.sites`` to ``django.contrib.admin.exceptions``. * The minimum supported version of SQLite is increased from 3.21.0 to 3.27.0. * Support for ``cx_Oracle`` < 8.3 is removed. * Executing SQL queries before the app registry has been fully populated now raises :exc:`RuntimeWarning`. * :exc:`~django.core.exceptions.BadRequest` is raised for non-UTF-8 encoded requests with the :mimetype:`application/x-www-form-urlencoded` content type. See :rfc:`1866` for more details. * The minimum supported version of ``colorama`` is increased to 0.4.6. * The minimum supported version of ``docutils`` is increased to 0.19. * Filtering querysets against overflowing integer values now always returns an empty queryset. As a consequence, you may need to use ``ExpressionWrapper()`` to :ref:`explicitly wrap <using-f-with-annotations>` arithmetic against integer fields in such cases. .. _deprecated-features-5.0: Features deprecated in 5.0 ========================== Miscellaneous ------------- * The ``DjangoDivFormRenderer`` and ``Jinja2DivFormRenderer`` transitional form renderers are deprecated. * Passing positional arguments ``name`` and ``violation_error_message`` to :class:`~django.db.models.BaseConstraint` is deprecated in favor of keyword-only arguments. * ``request`` is added to the signature of :meth:`.ModelAdmin.lookup_allowed`. Support for ``ModelAdmin`` subclasses that do not accept this argument is deprecated. * The ``get_joining_columns()`` method of ``ForeignObject`` and ``ForeignObjectRel`` is deprecated. Starting with Django 6.0, ``django.db.models.sql.datastructures.Join`` will no longer fallback to ``get_joining_columns()``. Subclasses should implement ``get_joining_fields()`` instead. * The ``ForeignObject.get_reverse_joining_columns()`` method is deprecated. * The default scheme for ``forms.URLField`` will change from ``"http"`` to ``"https"`` in Django 6.0. Set :setting:`FORMS_URLFIELD_ASSUME_HTTPS` transitional setting to ``True`` to opt into assuming ``"https"`` during the Django 5.x release cycle. * ``FORMS_URLFIELD_ASSUME_HTTPS`` transitional setting is deprecated. * Support for calling ``format_html()`` without passing args or kwargs will be removed. * Support for ``cx_Oracle`` is deprecated in favor of `oracledb`_ 1.3.2+ Python driver. * ``DatabaseOperations.field_cast_sql()`` is deprecated in favor of ``DatabaseOperations.lookup_cast()``. Starting with Django 6.0, ``BuiltinLookup.process_lhs()`` will no longer call ``field_cast_sql()``. Third-party database backends should implement ``lookup_cast()`` instead. * The ``django.db.models.enums.ChoicesMeta`` metaclass is renamed to ``ChoicesType``. * The ``Prefetch.get_current_queryset()`` method is deprecated. * The ``get_prefetch_queryset()`` method of related managers and descriptors is deprecated. Starting with Django 6.0, ``get_prefetcher()`` and ``prefetch_related_objects()`` will no longer fallback to ``get_prefetch_queryset()``. Subclasses should implement ``get_prefetch_querysets()`` instead. .. _`oracledb`: https://oracle.github.io/python-oracledb/ Features removed in 5.0 ======================= These features have reached the end of their deprecation cycle and are removed in Django 5.0.
