|
|
<django.core.mail.EmailMessage>` and
|
|
:class:`EmailMultiAlternatives.attachments
|
|

|
|
to regular tuples.
|
|
|
|
* :attr:`EmailMultiAlternatives.alternatives
|
|
<django.core.mail.EmailMultiAlternatives.alternatives>` is now a list of
|
|
named tuples, as opposed to regular tuples.
|
|
|
|
* The new :meth:`~django.core.mail.EmailMultiAlternatives.body_contains` method
|
|
returns a boolean indicating whether a provided text is contained in the
|
|
email ``body`` and in all attached MIME type ``text/*`` alternatives.
|
|
|
|
Error Reporting
|
|
~~~~~~~~~~~~~~~
|
|
|
|
* The attribute :attr:`.SafeExceptionReporterFilter.hidden_settings` now
|
|
treats values as sensitive if their name includes ``AUTH``.
|
|
|
|
File Storage
|
|
~~~~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
File Uploads
|
|
~~~~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Forms
|
|
~~~~~
|
|
|
|
* The new :class:`~django.forms.ColorInput` form widget is for entering a color
|
|
in ``rrggbb`` hexadecimal format and renders as ``<input type="color" ...>``.
|
|
Some browsers support a visual color picker interface for this input type.
|
|
|
|
* The new :class:`~django.forms.SearchInput` form widget is for entering search
|
|
queries and renders as ``<input type="search" ...>``.
|
|
|
|
* The new :class:`~django.forms.TelInput` form widget is for entering telephone
|
|
numbers and renders as ``<input type="tel" ...>``.
|
|
|
|
Generic Views
|
|
~~~~~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Internationalization
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Logging
|
|
~~~~~~~
|
|
|
|
* ...
|
|
|
|
Management Commands
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
* A new warning is printed to the console when running :djadmin:`runserver` that
|
|
``runserver`` is unsuitable for production. This warning can be hidden by
|
|
setting the :envvar:`HIDE_PRODUCTION_WARNING` environment variable to
|
|
``"true"``.
|
|
|
|
Migrations
|
|
~~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Models
|
|
~~~~~~
|
|
|
|
* The ``SELECT`` clause generated when using
|
|
:meth:`QuerySet.values()<django.db.models.query.QuerySet.values>` and
|
|
:meth:`~django.db.models.query.QuerySet.values_list` now matches the
|
|
specified order of the referenced expressions. Previously the order was based
|
|
of a set of counterintuitive rules which made query combination through
|
|
methods such as
|
|
:meth:`QuerySet.union()<django.db.models.query.QuerySet.union>` unpredictable.
|
|
|
|
* Added support for validation of model constraints which use a
|
|
:class:`~django.db.models.GeneratedField`.
|
|
|
|
* The new :attr:`.Expression.set_returning` attribute specifies that the
|
|
expression contains a set-returning function, enforcing subquery evaluation.
|
|
This is necessary for many Postgres set-returning functions.
|
|
|
|
* :attr:`CharField.max_length <django.db.models.CharField.max_length>` is no
|
|
longer required to be set on SQLite, which supports unlimited ``VARCHAR``
|
|
columns.
|
|
|
|
Requests and Responses
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* The new :meth:`.HttpRequest.get_preferred_type` method can be used to query
|
|
the preferred media type the client accepts.
|
|
|
|
Security
|
|
~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Serialization
|
|
~~~~~~~~~~~~~
|
|
|
|
* Each serialization format now defines a ``Deserializer`` class, rather than a
|
|
function, to improve extensibility when defining a
|
|
:ref:`custom serialization format <custom-serialization-formats>`.
|
|
|
|
Signals
|
|
~~~~~~~
|
|
|
|
* ...
|
|
|
|
Templates
|
|
~~~~~~~~~
|
|
|
|
* ...
|
|
|
|
Tests
|
|
~~~~~
|
|
|
|
* Stack frames from Django's custom assertions are now hidden. This makes test
|
|
failures easier to read and enables :option:`test --pdb` to directly enter
|
|
into the failing test method.
|
|
|
|
* Data loaded from :attr:`~django.test.TransactionTestCase.fixtures` and from
|
|
migrations enabled with :ref:`serialized_rollback=True
|
|
<test-case-serialized-rollback>` are now available during
|
|
``TransactionTestCase.setUpClass()``.
|
|
|
|
URLs
|
|
~~~~
|
|
|
|
* ...
|
|
|
|
Utilities
|
|
~~~~~~~~~
|
|
|
|
* :class:`~django.utils.safestring.SafeString` now returns
|
|
:py:data:`NotImplemented` in ``__add__`` for non-string right-hand side
|
|
values. This aligns with the :py:class:`str` addition behavior and allows
|
|
``__radd__`` to be used if available.
|
|
|
|
* :func:`~django.utils.html.format_html_join` now supports taking an iterable
|
|
of mappings, passing their contents as keyword arguments to
|
|
:func:`~django.utils.html.format_html`.
|
|
|
|
