Django 1.6 release notes - UNDER DEVELOPMENT
|
|
============================================
|
|
|
|
Welcome to Django 1.6!
|
|
|
|
These release notes cover the `new features`_, as well as some `backwards
|
|
incompatible changes`_ you'll want to be aware of when upgrading from Django
|
|
1.5 or older versions. We've also dropped some features, which are detailed in
|
|
:doc:`our deprecation plan </internals/deprecation>`, and we've `begun the
|
|
deprecation process for some features`_.
|
|

What's new in Django 1.6
|
|
========================
|
|
|
|
Simplified default project and app templates
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The default templates used by :djadmin:`startproject` and :djadmin:`startapp`
|
|
have been simplified and modernized. The :doc:`admin
|
|
</ref/contrib/admin/index>` is now enabled by default in new projects; the
|
|
:doc:`sites </ref/contrib/sites>` framework no longer is. :ref:`Language
|
|
detection <how-django-discovers-language-preference>` and :ref:`clickjacking
|
|
prevention <clickjacking-prevention>` are turned on.
|
|
|
|
If the default templates don't suit your tastes, you can use :ref:`custom
|
|
project and app templates <custom-app-and-project-templates>`.
|
|
|
|
Minor features
|
|
~~~~~~~~~~~~~~
|
|
|
|
* Authentication backends can raise ``PermissionDenied`` to immediately fail
|
|
the authentication chain.
|
|
|
|
* The HttpOnly flag can be set on the CSRF cookie with
|
|
:setting:`CSRF_COOKIE_HTTPONLY`.
|
|
|
|
* The ``assertQuerysetEqual()`` now checks for undefined order and raises
|
|
``ValueError`` if undefined order is spotted. The order is seen as
|
|
undefined if the given ``QuerySet`` isn't ordered and there are more than
|
|
one ordered values to compare against.
|
|
|
|
* Added :meth:`~django.db.models.query.QuerySet.earliest` for symmetry with
|
|
:meth:`~django.db.models.query.QuerySet.latest`.
|
|
|
|
* The default widgets for :class:`~django.forms.EmailField` and
|
|
:class:`~django.forms.URLField` use the new type attributes available in
|
|
HTML5 (type='email', type='url').
|
|
|
|
* The ``number`` argument for :ref:`lazy plural translations
|
|
<lazy-plural-translations>` can be provided at translation time rather than
|
|
at definition time.
|
|
|
|
* For custom management commands: Verification of the presence of valid
|
|
settings in commands that ask for it by using the
|
|
:attr:`~django.core.management.BaseCommand.can_import_settings` internal
|
|
option is now performed independently from handling of the locale that
|
|
should be active during the execution of the command. The latter can now be
|
|
influenced by the new
|
|
:attr:`~django.core.management.BaseCommand.leave_locale_alone` internal
|
|
option. See :ref:`management-commands-and-locales` for more details.
|
|
|
|
* The :attr:`~django.views.generic.edit.DeletionMixin.success_url` of
|
|
:class:`~django.views.generic.edit.DeletionMixin` is now interpolated with
|
|
its ``object``\'s ``__dict__``.
|
|
|
|
* :class:`~django.http.HttpResponseRedirect` and
|
|
:class:`~django.http.HttpResponsePermanentRedirect` now provide an ``url``
|
|
attribute (equivalent to the URL the response will redirect to).
|
|
|
|
Backwards incompatible changes in 1.6
|
|
=====================================
|
|
|
|
* The ``django.db.models.query.EmptyQuerySet`` can't be instantiated any more -
|
|
it is only usable as a marker class for checking if
|
|
:meth:`~django.db.models.query.QuerySet.none` has been called:
|
|
``isinstance(qs.none(), EmptyQuerySet)``
|
|
|
|
* If your CSS/Javascript code used to access HTML input widgets by type, you
|
|
should review it as ``type='text'`` widgets might be now output as
|
|
``type='email'`` or ``type='url'`` depending on their corresponding field type.
|
|
|
|
* Extraction of translatable literals from templates with the
|
|
:djadmin:`makemessages` command now correctly detects i18n constructs when
|
|
they are located after a ``{#`` / ``#}``-type comment on the same line. E.g.:
|
|
|
|
.. code-block:: html+django
|
|
|
|
{# A comment #}{% trans "This literal was incorrectly ignored. Not anymore" %}
|
|
|
|
* (Related to the above item.) Validation of the placement of
|
|
:ref:`translator-comments-in-templates` specified using ``{#`` / ``#}`` is now
|
|
stricter. All translator comments not located at the end of their respective
|
|
lines in a template are ignored and a warning is generated by
|
|
:djadmin:`makemessages` when it finds them. E.g.:
|
|
|
|
.. code-block:: html+django
|
|
|
|
{# Translators: This is ignored #}{% trans "Translate me" %}
|
|
{{ title }}{# Translators: Extracted and associated with 'Welcome' below #}
|
|
<h1>{% trans "Welcome" %}</h1>
|
|
|
|
.. warning::
|
|
|
|
In addition to the changes outlined in this section, be sure to review the
|
|
:doc:`deprecation plan </internals/deprecation>` for any features that
|
|
have been removed. If you haven't updated your code within the
|
|
deprecation timeline for a given feature, its removal may appear as a
|
|
backwards incompatible change.
|
|
|
|
Features deprecated in 1.6
|
|
==========================
|
|
|
|
``SEND_BROKEN_LINK_EMAILS`` setting
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
:class:`~django.middleware.common.CommonMiddleware` used to provide basic
|
|
reporting of broken links by email when ``SEND_BROKEN_LINK_EMAILS`` is set to
|
|
``True``.
|
|
|
|
Because of intractable ordering problems between
|
|
:class:`~django.middleware.common.CommonMiddleware` and
|
|
:class:`~django.middleware.locale.LocaleMiddleware`, this feature was split
|
|
out into a new middleware:
|
|
:class:`~django.middleware.common.BrokenLinkEmailsMiddleware`.
|
|
|
|
If you're relying on this feature, you should add
|
|
``'django.middleware.common.BrokenLinkEmailsMiddleware'`` to your
|
|
:setting:`MIDDLEWARE_CLASSES` setting and remove ``SEND_BROKEN_LINK_EMAILS``
|
|
from your settings.
|
|
|
|
``_has_changed`` method on widgets
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If you defined your own form widgets and defined the ``_has_changed`` method
|
|
on a widget, you should now define this method on the form field itself.
|
|
|
|
``module_name`` model meta attribute
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
``Model._meta.module_name`` was renamed to ``model_name``. Despite being a
|
|
private API, it will go through a regular deprecation path.
