Using select_related(...) across a nullable relation to a multi-table
model inheritance situation no longer excludes results. Thanks to AdamG
for a test demonstrating part of the problem.

Fixed some typos in the code (fixed#10586). Added more tests. Made the
tests compatible with Python 2.3. Improved the documentation by putting
the good news and common use-case right up front.

This began life as (part of) James Bennett's comment-utils app, and was adapted to be part of Django by Thejaswi Puthraya and Jannis Leidel. Thanks, all!

This work started life as Brian Beck's "django-batchadmin." It was rewritten for inclusion in Django by Alex Gaynor, Jannis Leidel (jezdez), and Martin Mahner (bartTC). Thanks, guys!

Most of the hard work for this was done by akaihola.
There are still possibly some problems with the i18n template tags,
since they are written quite differently and a few other bug fixes have
to made before they can be fixed.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@10119 bcc190cf-cafb-0310-a4f2-bffc1f526a37
Some template filters and tags understood single-quoted arguments, others
didn't. This makes everything consistent. Based on a patch from akaihola.
Fixed#7295.

The conditional processing decorator from r10114 wasn't parsing ETags
from an If-Match header correctly. Patch from Ivan Sagalaev (who also
did most of the work in r10114, before I rewrote parts of it and added
bonus bugs, although I forgot to thank him there).
git-svn-id: http://code.djangoproject.com/svn/django/trunk@10116 bcc190cf-cafb-0310-a4f2-bffc1f526a37
This provides support for views that can have their ETag and/or Last-modified
values computed much more quickly than the view itself. Supports all HTTP
verbs (not just GET).
Documentation and tests need a little more fleshing out (I'm not happy with the
documentation at the moment, since it's a bit backwards), but the functionality
is correct.

A custom manager on a related object that filtered away objects would prevent
those objects being deleted via the relation. This is now fixed.

Calling the super() version of __reduce__ in Model.__reduce__ led to infinite
loops in Python prior to 2.5. We don't do that any longer.

In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Large portions of this are needed for #5420, so I implemented it fully.
Thanks to Ryan Kelly for an initial patch to get this started.
Refs #5420.

We can't use the default manager in Model.save_base(), since we need to
retrieve existing objects which might be filtered out by that manager. We now
always use a plain Manager instance at that point (or something that can
replace it, such as a GeoManager), making all existing rows in the
database visible to the saving code.
The logic for detecting a "suitable replacement" plain base is the same as for
related fields: if the use_for_related_fields is set on the manager subclass,
we can use it. The general requirement here is that we want a base class that
returns the appropriate QuerySet subclass, but does not restrict the rows
returned.
Fixed#8990, #9527.
Refs #2698 (which is not fixed by this change, but it's the first part of a
larger change to fix that bug.)

Adding a get_db_prep_save() call to the UpdateQuery code path meant it
was being called twice if you updated an existing model attribute. This
change removes that double call and also makes TimeField.to_python() a
little more robust for the benefit of the Oracle backend (just in case).
git-svn-id: http://code.djangoproject.com/svn/django/trunk@10013 bcc190cf-cafb-0310-a4f2-bffc1f526a37
This allows a model to be defined which is not subject to database table
creation and removal. Useful for models that sit over existing tables or
database views.
Thanks to Alexander Myodov, Wolfgang Kriesing and Ryan Kelly for the bulk of
this patch.

Previously, you could explicitly assign None to a non-null ForeignKey
(or other) field when creating the model (Child(parent=None), etc). We
now throw an exception when you do that, which matches the behaviour
when you assign None to the attribute after creation.
Thanks to ales.zoulek@gmail.com and ondrej.kohout@gmail.com for some
analysis of this problem.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@9983 bcc190cf-cafb-0310-a4f2-bffc1f526a37
This fixes a broad class of bugs involving filters that look for missing
related models and fields. Most of them don't seem to have been reported
(the added tests cover the root cause). The exception is that this has
also fixed#9868.

Manually specifying both a OneToOneField(parent_link=True) and separate a
primary key field was causing invalid SQL to be generated. Thanks to Ramiro
Morales for some analysis on this one.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@9971 bcc190cf-cafb-0310-a4f2-bffc1f526a37
This includes a fairly large refactor of the update() query path (and
the initial portions of constructing the SQL for any query). The
previous code appears to have been only working more or less by accident
and was very fragile.

This is like "safe", except it operates on the individual elements of a
sequence, rather than treating the whole argument as a string.
