Django 1.2.4 release notes
|
|
==========================
|
|
|
|
Welcome to Django 1.2.4!
|
|
|
|
This is the fourth "bugfix" release in the Django 1.2 series,
|
|
improving the stability and performance of the Django 1.2 codebase.
|
|
|
|
With one exception, Django 1.2.4 maintains backwards compatibility
|
|
with Django 1.2.3. It also contains a number of fixes and other
|
|
improvements. Django 1.2.4 is a recommended upgrade for any
|
|
development or deployment currently using or targeting Django 1.2.
|
|
|
|
For full details on the new features, backwards incompatibilities, and
|
|
deprecated features in the 1.2 branch, see the :doc:`/releases/1.2`.
|
|
|
|
Backwards incompatible changes
|
|
==============================
|
|
|
|
Restricted filters in admin interface
|
|
-------------------------------------
|
|
|
|
The Django administrative interface, ``django.contrib.admin``, supports
|
|
filtering of displayed lists of objects by fields on the corresponding
|
|
models, including across database-level relationships. This is
|
|
implemented by passing lookup arguments in the querystring portion of
|
|
the URL, and options on the ModelAdmin class allow developers to
|
|
specify particular fields or relationships which will generate
|
|
automatic links for filtering.
|
|
|
|
One historically-undocumented and -unofficially-supported feature has
|
|
been the ability for a user with sufficient knowledge of a model's
|
|
structure and the format of these lookup arguments to invent useful
|
|
new filters on the fly by manipulating the querystring.
|
|
|
|
However, it has been demonstrated that this can be abused to gain
|
|
access to information outside of an admin user's permissions; for
|
|
example, an attacker with access to the admin and sufficient knowledge
|
|
of model structure and relations could construct query strings which --
|
|
with repeated use of regular-expression lookups supported by the
|
|
Django database API -- expose sensitive information such as users'
|
|
password hashes.
|
|
|
|
To remedy this, ``django.contrib.admin`` will now validate that
|
|
querystring lookup arguments either specify only fields on the model
|
|
being viewed, or cross relations which have been explicitly
|
|
allowed by the application developer using the preexisting
|
|
mechanism mentioned above. This is backwards-incompatible for any
|
|
users relying on the prior ability to insert arbitrary lookups.
|
|
|
|
One new feature
|
|
===============
|
|
|
|
Ordinarily, a point release would not include new features, but in the
|
|
case of Django 1.2.4, we have made an exception to this rule.
|
|
|
|
One of the bugs fixed in Django 1.2.4 involves a set of
|
|
circumstances whereby a running a test suite on a multiple database
|
|
configuration could cause the original source database (i.e., the
|
|
actual production database) to be dropped, causing catastrophic loss
|
|
of data. In order to provide a fix for this problem, it was necessary
|
|
to introduce a new setting -- :setting:`TEST_DEPENDENCIES` -- that
|
|
allows you to define any creation order dependencies in your database
|
|
configuration.
|
|
|
|
Most users -- even users with multiple-database configurations -- need
|
|
not be concerned about the data loss bug, or the manual configuration of
|
|
:setting:`TEST_DEPENDENCIES`. See the :ticket:`original problem report <14415>`
|
|
documentation on :ref:`controlling the creation order of test
|
|
databases <topics-testing-creation-dependencies>` for details.
|
|
|
|
GeoDjango
|
|
=========
|
|
|
|
The function-based :setting:`TEST_RUNNER` previously used to execute
|
|
the GeoDjango test suite, ``django.contrib.gis.tests.run_gis_tests``,
|
|
was finally deprecated in favor of a class-based test runner,
|
|
``django.contrib.gis.tests.GeoDjangoTestSuiteRunner``, added in this
|
|
release.
|
|
|
|
In addition, the GeoDjango test suite is now included when
|
|
:ref:`running the Django test suite <running-unit-tests>` with ``runtests.py``
|
|
and using :ref:`spatial database backends <spatial-backends>`.
