This setting does for new directories what FILE_UPLOAD_PERMISSIONS does for new files. Thanks jacob@ for the suggestion.

Django 1.7 release notes - UNDER DEVELOPMENT
|
||
============================================
|
||
|
||
Welcome to Django 1.7!
|
||
|
||
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
|
||
1.6 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`_.
|
||
|
||
.. _`new features`: `What's new in Django 1.7`_
|
||
.. _`backwards incompatible changes`: `Backwards incompatible changes in 1.7`_
|
||
.. _`begun the deprecation process for some features`: `Features deprecated in 1.7`_
|
||
|
||
Python compatibility
|
||
====================
|
||
|
||
Django 1.7 requires Python 2.7 or above, though we **highly recommend**
|
||
the latest minor release. Support for Python 2.6 has been dropped.
|
||
|
||
This change should affect only a small number of Django users, as most
|
||
operating-system vendors today are shipping Python 2.7 or newer as their default
|
||
version. If you're still using Python 2.6, however, you'll need to stick to
|
||
Django 1.6 until you can upgrade your Python version. Per :doc:`our support
|
||
policy </internals/release-process>`, Django 1.6 will continue to receive
|
||
security support until the release of Django 1.8.
|
||
|
||
What's new in Django 1.7
|
||
========================
|
||
|
||
Calling custom ``QuerySet`` methods from the ``Manager``
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
The :meth:`QuerySet.as_manager() <django.db.models.query.QuerySet.as_manager>`
|
||
class method has been added to :ref:`create Manager with QuerySet methods
|
||
<create-manager-with-queryset-methods>`.
|
||
|
||
Admin shortcuts support time zones
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
The "today" and "now" shortcuts next to date and time input widgets in the
|
||
admin are now operating in the :ref:`current time zone
|
||
<default-current-time-zone>`. Previously, they used the browser time zone,
|
||
which could result in saving the wrong value when it didn't match the current
|
||
time zone on the server.
|
||
|
||
In addition, the widgets now display a help message when the browser and
|
||
server time zone are different, to clarify how the value inserted in the field
|
||
will be interpreted.
|
||
|
||
Minor features
|
||
~~~~~~~~~~~~~~
|
||
|
||
* The new :attr:`UploadedFile.content_type_extra
|
||
<django.core.files.uploadedfile.UploadedFile.content_type_extra>` attribute
|
||
contains extra parameters passed to the ``content-type`` header on a file
|
||
upload.
|
||
|
||
* The ``enter`` argument was added to the
|
||
:data:`~django.test.signals.setting_changed` signal.
|
||
|
||
* The :meth:`QuerySet.update_or_create()
|
||
<django.db.models.query.QuerySet.update_or_create>` method was added.
|
||
|
||
* :attr:`~django.db.models.Options.app_label` is no longer required for models
|
||
that are defined in a ``models`` package within an app.
|
||
|
||
* The :meth:`Context.push() <django.template.Context.push>` method now returns
|
||
a context manager which automatically calls :meth:`pop()
|
||
<django.template.Context.pop>` upon exiting the ``with`` statement.
|
||
Additionally, :meth:`push() <django.template.Context.push>` now accepts
|
||
parameters that are passed to the ``dict`` constructor used to build the new
|
||
context level.
|
||
|
||
* The :class:`~django.utils.feedgenerator.Atom1Feed` syndication feed's
|
||
``updated`` element now utilizes `updateddate` instead of ``pubdate``,
|
||
allowing the ``published`` element to be included in the feed (which
|
||
relies on ``pubdate``).
|
||
|
||
* Buttons in :mod:`django.contrib.admin` now use the ``border-radius`` CSS
|
||
property for rounded corners rather than GIF background images.
|
||
|
||
* Some admin templates now have ``app-<app_name>`` and ``model-<model_name>``
|
||
classes in their ``<body>`` tag to allow customizing the CSS per app or per
|
||
model.
|
||
|
||
* The admin changelist cells now have a ``field-<field_name>`` class in the
|
||
HTML to enable style customizations.
|
||
|
||
* :func:`~django.core.mail.send_mail` now accepts an ``html_message``
|
||
parameter for sending a multipart ``text/plain`` and ``text/html`` email.
|
||
|
||
* The :djadminopt:`--no-color` option for ``django-admin.py`` allows you to
|
||
disable the colorization of management command output.
|
||
|
||
* The :mod:`sitemap framework<django.contrib.sitemaps>` now makes use of
|
||
:attr:`~django.contrib.sitemaps.Sitemap.lastmod` to set a ``Last-Modified``
|
||
header in the response. This makes it possible for the
|
||
:class:`~django.middleware.http.ConditionalGetMiddleware` to handle
|
||
conditional ``GET`` requests for sitemaps which set ``lastmod``.
|
||
|
||
* You can override the new :meth:`AuthenticationForm.confirm_login_allowed()
|
||
<django.contrib.auth.forms.AuthenticationForm.confirm_login_allowed>` method
|
||
to more easily customize the login policy.
|
||
|
||
* :attr:`Field.choices<django.db.models.Field.choices>` now allows you to
|
||
customize the "empty choice" label by including a tuple with an empty string
|
||
or ``None`` for the key and the custom label as the value. The default blank
|
||
option ``"----------"`` will be omitted in this case.
|
||
|
||
* The admin's search fields can now be customized per-request thanks to the new
|
||
:meth:`django.contrib.admin.ModelAdmin.get_search_fields` method.
|
||
|
||
* The :meth:`ModelAdmin.get_fields()
|
||
<django.contrib.admin.ModelAdmin.get_fields>` method may be overridden to
|
||
customize the value of :attr:`ModelAdmin.fields
|
||
<django.contrib.admin.ModelAdmin.fields>`.
|
||
|
||
* :func:`django.contrib.auth.views.password_reset` takes an optional
|
||
``html_email_template_name`` parameter used to send a multipart HTML email
|
||
for password resets.
|
||
|
||
* :class:`~django.forms.MultiValueField` allows optional subfields by setting
|
||
the ``require_all_fields`` argument to ``False``. The ``required`` attribute
|
||
for each individual field will be respected, and a new ``incomplete``
|
||
validation error will be raised when any required fields are empty.
|
||
|
||
* The :meth:`~django.forms.Form.clean` method on a form no longer needs to
|
||
return ``self.cleaned_data``. If it does return a changed dictionary then
|
||
that will still be used.
|
||
|
||
* The new :attr:`~django.db.models.Options.default_permissions` model
|
||
``Meta`` option allows you to customize (or disable) creation of the default
|
||
add, change, and delete permissions.
|
||
|
||
* The :func:`~django.contrib.auth.decorators.permission_required` decorator can
|
||
take a list of permissions as well as a single permission.
|
||
|
||
* The new :setting:`FILE_UPLOAD_DIRECTORY_PERMISSIONS` setting controls
|
||
the file system permissions of directories created during file upload, like
|
||
:setting:`FILE_UPLOAD_PERMISSIONS` does for the files themselves.
|
||
|
||
Backwards incompatible changes in 1.7
|
||
=====================================
|
||
|
||
.. 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.
|
||
|
||
Miscellaneous
|
||
~~~~~~~~~~~~~
|
||
|
||
* The :meth:`django.core.files.uploadhandler.FileUploadHandler.new_file()`
|
||
method is now passed an additional ``content_type_extra`` parameter. If you
|
||
have a custom :class:`~django.core.files.uploadhandler.FileUploadHandler`
|
||
that implements ``new_file()``, be sure it accepts this new parameter.
|
||
|
||
* :class:`ModelFormSet<django.forms.models.BaseModelFormSet>`’s no longer
|
||
delete instances when ``save(commit=False)`` is called. See
|
||
:attr:`~django.forms.formsets.BaseFormSet.can_delete` for instructions on how
|
||
to manually delete objects from deleted forms.
|
||
|
||
* Loading empty fixtures emits a ``RuntimeWarning`` rather than raising
|
||
:class:`~django.core.management.CommandError`.
|
||
|
||
* :func:`django.contrib.staticfiles.views.serve` will now raise an
|
||
:exc:`~django.http.Http404` exception instead of
|
||
:exc:`~django.core.exceptions.ImproperlyConfigured` when :setting:`DEBUG`
|
||
is ``False``. This change removes the need to conditionally add the view to
|
||
your root URLconf, which in turn makes it safe to reverse by name. It also
|
||
removes the ability for visitors to generate spurious HTTP 500 errors by
|
||
requesting static files that don't exist or haven't been collected yet.
|
||
|
||
Features deprecated in 1.7
|
||
==========================
|
||
|
||
``django.utils.dictconfig``/``django.utils.importlib``
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
``django.utils.dictconfig`` and ``django.utils.importlib`` were copies of
|
||
respectively :mod:`logging.config` and :mod:`importlib` provided for Python
|
||
versions prior to 2.7. They have been deprecated.
|
||
|
||
``django.utils.unittest``
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
``django.utils.unittest`` provided uniform access to the ``unittest2`` library
|
||
on all Python versions. Since ``unittest2`` became the standard library's
|
||
:mod:`unittest` module in Python 2.7, and Django 1.7 drops support for older
|
||
Python versions, this module isn't useful anymore. It has been deprecated. Use
|
||
:mod:`unittest` instead.
|
||
|
||
``django.utils.datastructures.SortedDict``
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
As :class:`~collections.OrderedDict` was added to the standard library in
|
||
Python 2.7, :class:`~django.utils.datastructures.SortedDict` is no longer
|
||
needed and has been deprecated.
|
||
|
||
Custom SQL location for models package
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
Previously, if models were organized in a package (``myapp/models/``) rather
|
||
than simply ``myapp/models.py``, Django would look for :ref:`initial SQL data
|
||
<initial-sql>` in ``myapp/models/sql/``. This bug has been fixed so that Django
|
||
will search ``myapp/sql/`` as documented. The old location will continue to
|
||
work until Django 1.9.
|
||
|
||
``declared_fieldsets`` attribute on ``ModelAdmin.``
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
``ModelAdmin.declared_fieldsets`` was deprecated. Despite being a private API,
|
||
it will go through a regular deprecation path. This attribute was mostly used
|
||
by methods that bypassed ``ModelAdmin.get_fieldsets()`` but this was considered
|
||
a bug and has been addressed.
