Backwards-incompatible changes
|
|
==============================
|
|
|
|
CSRF Protection
|
|
---------------
|
|
|
|
There have been large changes to the way that CSRF protection works, detailed in
|
|
:ref:`the CSRF documentaton <ref-contrib-csrf>`. The following are the major
|
|
changes that developers must be aware of:
|
|
|
|
* ``CsrfResponseMiddleware`` and ``CsrfMiddleware`` have been deprecated, and
|
|
will be removed completely in Django 1.4, in favour of a template tag that
|
|
should be inserted into forms.
|
|
|
|
* All contrib apps use a ``csrf_protect`` decorator to protect the view. This
|
|
requires the use of the csrf_token template tag in the template, so if you
|
|
have used custom templates for contrib views, you MUST READ THE UPGRADE
|
|
INSTRUCTIONS to fix those templates.
|
|
|
|
* ``CsrfViewMiddleware`` is included in :setting:`MIDDLEWARE_CLASSES` by
|
|
default. This turns on CSRF protection by default, so that views that accept
|
|
POST requests need to be written to work with the middleware. Instructions
|
|
on how to do this are found in the CSRF docs.
|
|
|
|
* All of the CSRF has moved from contrib to core (with backwards compatible
|
|
imports in the old locations, which are deprecated).
|
|
|
|
LazyObject
|
|
----------
|
|
|
|
``LazyObject`` is an undocumented utility class used for lazily wrapping other
|
|
objects of unknown type. In Django 1.1 and earlier, it handled introspection in
|
|
a non-standard way, depending on wrapped objects implementing a public method
|
|
``get_all_members()``. Since this could easily lead to name clashes, it has been
|
|
changed to use the standard method, involving ``__members__`` and ``__dir__()``.
|
|
If you used ``LazyObject`` in your own code, and implemented the
|
|
``get_all_members()`` method for wrapped objects, you need to make the following
|
|
changes:
|
|
|
|
* If your class does not have special requirements for introspection (i.e. you
|
|
have not implemented ``__getattr__()`` or other methods that allow for
|
|
attributes not discoverable by normal mechanisms), you can simply remove the
|
|
``get_all_members()`` method. The default implementation on ``LazyObject``
|
|
will do the right thing.
|
|
|
|
* If you have more complex requirements for introspection, first rename the
|
|
``get_all_members()`` method to ``__dir__()``. This is the standard method,
|
|
from Python 2.6 onwards, for supporting introspection. If you are require
|
|
support for Python < 2.6, add the following code to the class::
|
|
|
|
__members__ = property(lambda self: self.__dir__())
|
