|
|
|
* ``allow_syncdb`` on database routers will no longer automatically become
|
|
``allow_migrate``.

|
|
become compulsory for all apps unless you pass the ``--run-syncdb`` option to
|
|
``migrate``.

* The SQL management commands for apps without migrations, ``sql``, ``sqlall``,
|
|
``sqlclear``, ``sqldropindexes``, and ``sqlindexes``, will be removed.

|
|
data will be removed.
|
|
|

|
|
declare an explicit :attr:`~django.db.models.Options.app_label`.
|
|
Furthermore, it won't be possible to import them before their application
|
|
is loaded. In particular, it won't be possible to import models inside
|
|
the root package of their application.
|
|
|
|

|
|
removed. Please deploy your project using WSGI.

|
|
|
|
* Instances of ``util.py`` in the Django codebase have been renamed to
|
|

|
|

|
|
|
|
* ``django.core.cache.get_cache`` will be removed. Add suitable entries

|
|
|
|
* Passing callable arguments to querysets will no longer be possible.
|
|
|

|
|
``requires_system_checks``. Admin validators will be replaced by admin
|
|
checks.
|
|
|
|
* The ``ModelAdmin.validator_class`` and ``default_validator_class`` attributes
|
|
will be removed.
|
|
|
|
* ``ModelAdmin.validate()`` will be removed.
|
|
|
|
* ``django.db.backends.DatabaseValidation.validate_field`` will be removed in
|
|
favor of the ``check_field`` method.
|
|
|
|
* The ``validate`` management command will be removed.
|
|
|
|
* ``django.utils.module_loading.import_by_path`` will be removed in favor of

``django.utils.module_loading.import_string``.
|
|
|
|
* ``ssi`` and ``url`` template tags will be removed from the ``future`` template
|
|
tag library (used during the 1.3/1.4 deprecation period).
|
|
|
|

|
|
details on these changes.
|
|
|
|
* ``django.contrib.comments`` will be removed.
|
|
|
|
* The following transaction management APIs will be removed:
|
|
|
|
- ``TransactionMiddleware``,
|
|
- the decorators and context managers ``autocommit``, ``commit_on_success``,
|
|
and ``commit_manually``, defined in ``django.db.transaction``,
|
|
- the functions ``commit_unless_managed`` and ``rollback_unless_managed``,
|
|
also defined in ``django.db.transaction``,
|
|
- the ``TRANSACTIONS_MANAGED`` setting.
|
|
|
|
* The :ttag:`cycle` and :ttag:`firstof` template tags will auto-escape their
|
|
arguments. In 1.6 and 1.7, this behavior is provided by the version of these
|
|
tags in the ``future`` template tag library.
|
|
|
|
* The ``SEND_BROKEN_LINK_EMAILS`` setting will be removed. Add the
|
|
:class:`django.middleware.common.BrokenLinkEmailsMiddleware` middleware to
|
|
your ``MIDDLEWARE_CLASSES`` setting instead.
|
|
|
|
* ``django.middleware.doc.XViewMiddleware`` will be removed. Use
|
|
``django.contrib.admindocs.middleware.XViewMiddleware`` instead.
|
|
|
|
* ``Model._meta.module_name`` was renamed to ``model_name``.
|
|
|
|
* Remove the backward compatible shims introduced to rename ``get_query_set``
|
|
and similar queryset methods. This affects the following classes:
|
|
``BaseModelAdmin``, ``ChangeList``, ``BaseCommentNode``,
|
|
``GenericForeignKey``, ``Manager``, ``SingleRelatedObjectDescriptor`` and
|
|
``ReverseSingleRelatedObjectDescriptor``.
|
|
|
|
* Remove the backward compatible shims introduced to rename the attributes
|
|
``ChangeList.root_query_set`` and ``ChangeList.query_set``.
|
|
|
|
* ``django.views.defaults.shortcut`` will be removed, as part of the
|
|
goal of removing all ``django.contrib`` references from the core
|
|
Django codebase. Instead use
|
|
``django.contrib.contenttypes.views.shortcut``. ``django.conf.urls.shortcut``
|
|
will also be removed.
|
|
|
|
* Support for the Python Imaging Library (PIL) module will be removed, as it
|
|
no longer appears to be actively maintained & does not work on Python 3.
|
|
|
|
* The following private APIs will be removed:
|
|
|
|
- ``django.db.backend``
|
|
- ``django.db.close_connection()``
|
|
- ``django.db.backends.creation.BaseDatabaseCreation.set_autocommit()``
|
|
- ``django.db.transaction.is_managed()``
|
|
- ``django.db.transaction.managed()``
|
|
|
|
* ``django.forms.widgets.RadioInput`` will be removed in favor of
|
|
``django.forms.widgets.RadioChoiceInput``.
|
|
|
|
* The module ``django.test.simple`` and the class
|
|
``django.test.simple.DjangoTestSuiteRunner`` will be removed. Instead use
|
|
``django.test.runner.DiscoverRunner``.
|
|
|
|
* The module ``django.test._doctest`` will be removed. Instead use the doctest
|
|
module from the Python standard library.
|
|
|
|
* The ``CACHE_MIDDLEWARE_ANONYMOUS_ONLY`` setting will be removed.
|
|
|
|
* Usage of the hard-coded *Hold down "Control", or "Command" on a Mac, to select
|
|
more than one.* string to override or append to user-provided ``help_text`` in
|
|
forms for ManyToMany model fields will not be performed by Django anymore
|
|
either at the model or forms layer.
|
|
|
|
* The ``Model._meta.get_(add|change|delete)_permission`` methods will
|
|
be removed.
|
|
|
|
* The session key ``django_language`` will no longer be read for backwards
|
|
compatibility.
|
|
|
|
* Geographic Sitemaps will be removed
|
|
(``django.contrib.gis.sitemaps.views.index`` and
|
|
``django.contrib.gis.sitemaps.views.sitemap``).
|
|
|
|
* ``django.utils.html.fix_ampersands``, the ``fix_ampersands`` template filter and
|
|
``django.utils.html.clean_html`` will be removed following an accelerated deprecation.

|
|
|
|
See the :ref:`Django 1.5 release notes<deprecated-features-1.5>` for more
|
|
details on these changes.
|
|
|
|
* The module ``django.utils.simplejson`` will be removed. The standard library
|
|
provides :mod:`json` which should be used instead.
|
|
|
|
* The function ``django.utils.itercompat.product`` will be removed. The Python
|
|
builtin version should be used instead.
|
|
|
|
* Auto-correction of INSTALLED_APPS and TEMPLATE_DIRS settings when they are
|
|
specified as a plain string instead of a tuple will be removed and raise an
|
|
exception.
|
|
|
|
* The ``mimetype`` argument to the ``__init__`` methods of
|
|
:class:`~django.http.HttpResponse`,
|
|
:class:`~django.template.response.SimpleTemplateResponse`, and
|
|
:class:`~django.template.response.TemplateResponse`, will be removed.
|
|
``content_type`` should be used instead. This also applies to the
|
|
``render_to_response()`` shortcut and the sitemap views,
|
|
:func:`~django.contrib.sitemaps.views.index` and
|
|
:func:`~django.contrib.sitemaps.views.sitemap`.
|
|
|
|
* When :class:`~django.http.HttpResponse` is instantiated with an iterator,
|
|
or when :attr:`~django.http.HttpResponse.content` is set to an iterator,
|
|
that iterator will be immediately consumed.
|
|
|
|
* The ``AUTH_PROFILE_MODULE`` setting, and the ``get_profile()`` method on
|
|
the User model, will be removed.
|
|
|
|
* The ``cleanup`` management command will be removed. It's replaced by
|
|
``clearsessions``.
|
|
|
|
* The ``daily_cleanup.py`` script will be removed.
|
|
|
|
* The ``depth`` keyword argument will be removed from
|
|
:meth:`~django.db.models.query.QuerySet.select_related`.
|
|
|
|
* The undocumented ``get_warnings_state()``/``restore_warnings_state()``
|
|
functions from :mod:`django.test.utils` and the ``save_warnings_state()``/
|
|
``restore_warnings_state()``
|
|
:ref:`django.test.*TestCase <django-testcase-subclasses>` methods are
|
|
deprecated. Use the :class:`warnings.catch_warnings` context manager
|
|
available starting with Python 2.6 instead.
|
|
|
|
* The undocumented ``check_for_test_cookie`` method in
|
|
:class:`~django.contrib.auth.forms.AuthenticationForm` will be removed
|
|
following an accelerated deprecation. Users subclassing this form should
|
|
remove calls to this method, and instead ensure that their auth related views
|
|
are CSRF protected, which ensures that cookies are enabled.
|
|
|
|
* The version of ``django.contrib.auth.views.password_reset_confirm()`` that
|
|
supports base36 encoded user IDs
|
|
(``django.contrib.auth.views.password_reset_confirm_uidb36``) will be
|
|
removed. If your site has been running Django 1.6 for more than
|
|
:setting:`PASSWORD_RESET_TIMEOUT_DAYS`, this change will have no effect. If
|
|
not, then any password reset links generated before you upgrade to Django 1.7
|
|
won't work after the upgrade.
|
|
|
|
* The ``django.utils.encoding.StrAndUnicode`` mix-in will be removed.

See the :ref:`Django 1.4 release notes<deprecated-features-1.4>` for more
|
|
details on these changes.
|
|
|
|
* ``django.contrib.databrowse`` will be removed.
|
|
|
|
* ``django.contrib.localflavor`` will be removed following an accelerated
|
|
deprecation.
|
|
|
|
* ``django.contrib.markup`` will be removed following an accelerated
|
|
deprecation.
|
|
|
|
* The compatibility modules ``django.utils.copycompat`` and
|
|
``django.utils.hashcompat`` as well as the functions
|
|
``django.utils.itercompat.all`` and ``django.utils.itercompat.any`` will
|
|
be removed. The Python builtin versions should be used instead.
|
|
|
|
* The ``csrf_response_exempt`` and ``csrf_view_exempt`` decorators will
|
|
be removed. Since 1.4 ``csrf_response_exempt`` has been a no-op (it
|
|
returns the same function), and ``csrf_view_exempt`` has been a
|
|
synonym for ``django.views.decorators.csrf.csrf_exempt``, which should
|
|
be used to replace it.
|
|
|
|
* The ``django.core.cache.backends.memcached.CacheClass`` backend
|
|
was split into two in Django 1.3 in order to introduce support for
|
|
PyLibMC. The historical ``CacheClass`` will be removed in favor of
|
|
``django.core.cache.backends.memcached.MemcachedCache``.
|
|
|
|
* The UK-prefixed objects of ``django.contrib.localflavor.uk`` will only
|
|
be accessible through their GB-prefixed names (GB is the correct
|
|
ISO 3166 code for United Kingdom).
|
|
|
|
* The ``IGNORABLE_404_STARTS`` and ``IGNORABLE_404_ENDS`` settings have been
|
|
superseded by :setting:`IGNORABLE_404_URLS` in the 1.4 release. They will be
|
|
removed.
|
|
|
|
* The form wizard has been refactored to use class-based views with pluggable
|
|
backends in 1.4. The previous implementation will be removed.
|
|
|
|
* Legacy ways of calling
|
|
:func:`~django.views.decorators.cache.cache_page` will be removed.
|
|
|
|
* The backward-compatibility shim to automatically add a debug-false
|
|
filter to the ``'mail_admins'`` logging handler will be removed. The
|
|
:setting:`LOGGING` setting should include this filter explicitly if
|
|
it is desired.
|
|
|
|
* The builtin truncation functions ``django.utils.text.truncate_words()``
|
|
and ``django.utils.text.truncate_html_words()`` will be removed in
|
|
favor of the ``django.utils.text.Truncator`` class.
|
|
|
|
* The ``django.contrib.gis.geoip.GeoIP`` class was moved to
|
|
``django.contrib.gis.geoip`` in 1.4 -- the shortcut in
|
|
``django.contrib.gis.utils`` will be removed.
|
|
|
|
* ``django.conf.urls.defaults`` will be removed. The functions
|
|
``include()``, ``patterns()``, and ``url()``, plus
|
|
:data:`~django.conf.urls.handler404` and :data:`~django.conf.urls.handler500`
|
|
are now available through ``django.conf.urls``.
|
|
|
|
* The functions ``setup_environ()`` and ``execute_manager()`` will be removed
|
|
from :mod:`django.core.management`. This also means that the old (pre-1.4)
|
|
style of :file:`manage.py` file will no longer work.
|
|
|
|
* Setting the ``is_safe`` and ``needs_autoescape`` flags as attributes of
|
|
template filter functions will no longer be supported.
|
|
|
|
* The attribute ``HttpRequest.raw_post_data`` was renamed to ``HttpRequest.body``
|
|
in 1.4. The backward compatibility will be removed --
|
|
``HttpRequest.raw_post_data`` will no longer work.
|
|
|
|
* The value for the ``post_url_continue`` parameter in
|
|
``ModelAdmin.response_add()`` will have to be either ``None`` (to redirect
|
|
to the newly created object's edit page) or a pre-formatted url. String
|
|
formats, such as the previous default ``'../%s/'``, will not be accepted any
|
|
more.

See the :ref:`Django 1.3 release notes<deprecated-features-1.3>` for more
|
|
details on these changes.
|
|
|
|
* Starting Django without a :setting:`SECRET_KEY` will result in an exception
|
|
rather than a ``DeprecationWarning``. (This is accelerated from the usual
|
|
deprecation path; see the :doc:`Django 1.4 release notes</releases/1.4>`.)
|
|
|
|
* The ``mod_python`` request handler will be removed. The ``mod_wsgi``
|
|
handler should be used instead.
|
|
|
|
* The ``template`` attribute on ``django.test.client.Response``
|
|
objects returned by the :ref:`test client <test-client>` will be removed.
|
|
The :attr:`~django.test.Response.templates` attribute should be
|
|
used instead.
|
|
|
|
* The ``django.test.simple.DjangoTestRunner`` will be removed.
|
|
Instead use a ``unittest``-native class. The features of the
|
|
``django.test.simple.DjangoTestRunner`` (including fail-fast and
|
|
Ctrl-C test termination) can be provided by :class:`unittest.TextTestRunner`.
|
|
|
|
* The undocumented function
|
|
``django.contrib.formtools.utils.security_hash`` will be removed,
|
|
instead use ``django.contrib.formtools.utils.form_hmac``
|
|
|
|
* The function-based generic view modules will be removed in favor of their
|
|
class-based equivalents, outlined :doc:`here
|
|
</topics/class-based-views/index>`.
|
|
|
|
* The ``django.core.servers.basehttp.AdminMediaHandler`` will be
|
|
removed. In its place use
|
|
``django.contrib.staticfiles.handlers.StaticFilesHandler``.
|
|
|
|
* The template tags library ``adminmedia`` and the template tag ``{%
|
|
admin_media_prefix %}`` will be removed in favor of the generic static files
|
|
handling. (This is faster than the usual deprecation path; see the
|
|
:doc:`Django 1.4 release notes</releases/1.4>`.)
|
|
|
|
* The ``url`` and ``ssi`` template tags will be modified so that the first
|
|
argument to each tag is a template variable, not an implied string. In 1.4,
|
|
this behavior is provided by a version of the tag in the ``future`` template
|
|
tag library.
|
|
|
|
* The ``reset`` and ``sqlreset`` management commands will be removed.
|
|
|
|
* Authentication backends will need to support an inactive user
|
|
being passed to all methods dealing with permissions.
|
|
The ``supports_inactive_user`` attribute will no longer be checked
|
|
and can be removed from custom backends.
|
|
|
|
* :meth:`~django.contrib.gis.geos.GEOSGeometry.transform` will raise
|
|
a :class:`~django.contrib.gis.geos.GEOSException` when called
|
|
on a geometry with no SRID value.
|
|
|
|
* ``django.http.CompatCookie`` will be removed in favor of
|
|
``django.http.SimpleCookie``.
|
|
|
|
* ``django.core.context_processors.PermWrapper`` and
|
|
``django.core.context_processors.PermLookupDict`` will be removed in
|
|
favor of the corresponding
|
|
``django.contrib.auth.context_processors.PermWrapper`` and
|
|
``django.contrib.auth.context_processors.PermLookupDict``, respectively.
|
|
|
|
* The :setting:`MEDIA_URL` or :setting:`STATIC_URL` settings will be
|
|
required to end with a trailing slash to ensure there is a consistent
|
|
way to combine paths in templates.
|
|
|
|
* ``django.db.models.fields.URLField.verify_exists`` will be removed. The
|
|
feature was deprecated in 1.3.1 due to intractable security and
|
|
performance issues and will follow a slightly accelerated deprecation
|
|
timeframe.
|
|
|
|
* Translations located under the so-called *project path* will be ignored during
|
|
the translation building process performed at runtime. The
|
|
:setting:`LOCALE_PATHS` setting can be used for the same task by including the
|
|
filesystem path to a ``locale`` directory containing non-app-specific
|
|
translations in its value.
|
|
|
|
* The Markup contrib app will no longer support versions of Python-Markdown
|
|
library earlier than 2.1. An accelerated timeline was used as this was
|
|
a security related deprecation.
|
|
|
|
* The ``CACHE_BACKEND`` setting will be removed. The cache backend(s) should be
|
|
specified in the :setting:`CACHES` setting.

details on these changes.
|
|
|
|
* ``CsrfResponseMiddleware`` and ``CsrfMiddleware`` will be removed. Use
|
|
the ``{% csrf_token %}`` template tag inside forms to enable CSRF
|
|
protection. ``CsrfViewMiddleware`` remains and is enabled by default.
|
|
|
|
* The old imports for CSRF functionality (``django.contrib.csrf.*``),
|
|
which moved to core in 1.2, will be removed.
|
|
|

* The ``django.contrib.gis.db.backend`` module will be removed in favor

of the specific backends.

* ``SMTPConnection`` will be removed in favor of a generic Email backend API.
|
|
|
|
* The many to many SQL generation functions on the database backends
|
|
will be removed.
|
|
|
|
* The ability to use the ``DATABASE_*`` family of top-level settings to
|
|
define database connections will be removed.
|
|
|
|
* The ability to use shorthand notation to specify a database backend
|
|
(i.e., ``sqlite3`` instead of ``django.db.backends.sqlite3``) will be
|
|
removed.
|
|
|
|
* The ``get_db_prep_save``, ``get_db_prep_value`` and
|
|
``get_db_prep_lookup`` methods will have to support multiple databases.
|
|
|
|
* The ``Message`` model (in ``django.contrib.auth``), its related
|
|
manager in the ``User`` model (``user.message_set``), and the
|
|
associated methods (``user.message_set.create()`` and
|
|
``user.get_and_delete_messages()``), will be removed. The
|
|
:doc:`messages framework </ref/contrib/messages>` should be used
|
|
instead. The related ``messages`` variable returned by the
|
|
auth context processor will also be removed. Note that this
|
|
means that the admin application will depend on the messages
|
|
context processor.
|
|
|
|
* Authentication backends will need to support the ``obj`` parameter for
|
|
permission checking. The ``supports_object_permissions`` attribute
|
|
will no longer be checked and can be removed from custom backends.
|
|
|
|
* Authentication backends will need to support the ``AnonymousUser`` class
|
|
being passed to all methods dealing with permissions. The
|
|
``supports_anonymous_user`` variable will no longer be checked and can be
|
|
removed from custom backends.
|
|
|
|
* The ability to specify a callable template loader rather than a
|
|
``Loader`` class will be removed, as will the ``load_template_source``
|
|
functions that are included with the built in template loaders for
|
|
backwards compatibility.
|
|
|
|
* ``django.utils.translation.get_date_formats()`` and
|
|
``django.utils.translation.get_partial_date_formats()``. These functions
|
|
will be removed; use the locale-aware
|
|
``django.utils.formats.get_format()`` to get the appropriate formats.
|
|
|
|
* In ``django.forms.fields``, the constants: ``DEFAULT_DATE_INPUT_FORMATS``,
|
|
``DEFAULT_TIME_INPUT_FORMATS`` and
|
|
``DEFAULT_DATETIME_INPUT_FORMATS`` will be removed. Use
|
|
``django.utils.formats.get_format()`` to get the appropriate
|
|
formats.
|
|
|
|
* The ability to use a function-based test runner will be removed,
|
|
along with the ``django.test.simple.run_tests()`` test runner.
|
|
|
|
* The ``views.feed()`` view and ``feeds.Feed`` class in
|
|
``django.contrib.syndication`` will be removed. The class-based view
|
|
``views.Feed`` should be used instead.
|
|
|
|
* ``django.core.context_processors.auth``. This release will
|
|
remove the old method in favor of the new method in
|
|
``django.contrib.auth.context_processors.auth``.
|
|
|
|
* The ``postgresql`` database backend will be removed, use the
|
|
``postgresql_psycopg2`` backend instead.
|
|
|
|
* The ``no`` language code will be removed and has been replaced by the
|
|
``nb`` language code.
|
|
|
|
* Authentication backends will need to define the boolean attribute
|
|
``supports_inactive_user`` until version 1.5 when it will be assumed that
|
|
all backends will handle inactive users.
|
|
|
|
* ``django.db.models.fields.XMLField`` will be removed. This was
|
|
deprecated as part of the 1.3 release. An accelerated deprecation
|
|
schedule has been used because the field hasn't performed any role
|
|
beyond that of a simple ``TextField`` since the removal of ``oldforms``.
|
|
All uses of ``XMLField`` can be replaced with ``TextField``.
|
|
|
|
* The undocumented ``mixin`` parameter to the ``open()`` method of
|
|
``django.core.files.storage.Storage`` (and subclasses) will be removed.

details on these changes.
|
|
|
|
* ``AdminSite.root()``. This method of hooking up the admin URLs will be
|
|
removed in favor of including ``admin.site.urls``.
|
|
|
|
* Authentication backends need to define the boolean attributes
|
|
``supports_object_permissions`` and ``supports_anonymous_user`` until
|
|
version 1.4, at which point it will be assumed that all backends will
|
|
support these options.
