Russell Keith-Magee 5e2d38465a Fixed #10847 -- Modified handling of extra() to use a masking strategy, rather than last-minute trimming. Thanks to Tai Lee for the report, and Alex Gaynor for his work on the patch.
This enables querysets with an extra clause to be used in an __in filter; as a side effect, it also means that as_sql() now returns the correct result for any query with an extra clause.

Malcolm Tredinnick 29050ef999 Fixed #5420 -- Added support for delayed loading of model fields.
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.

Malcolm Tredinnick 35f934f5a7 Pass values through get_db_prep_save() in a QuerySet.update() call.
This removes a long-standing FIXME in the update() handling and allows for
greater flexibility in the values passed in. In particular, it brings updates
into line with saves for django.contrib.gis fields, so fixed #10411.

Malcolm Tredinnick 923f78f504 Improved table join handling for comparisons against NULL.
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.

Malcolm Tredinnick 0e93f60c7f Fixed #10362 -- An update() that only affects a parent model no longer crashes.
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.

2009-03-04 05:34:01 +00:00
Malcolm Tredinnick 14c8e5227a Changed the row count value returned from update queries in some cases.
If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.
