Aymeric Augustin 4a56a93cc4 Moved the new app cache inside core. 2013-12-17 10:17:46 +01:00
Aymeric Augustin b3d5efe23f Restored deprecated aliases for functions in django.db.models.
Thanks Marc Tamlyn for the suggestion.

Aymeric Augustin 5ba743e262 Made it possible to create apps without a models module.
This commit reverts f44c4a5d0f and 39bbd165.

django.test.simple will be updated in a separate commit as it requires
invasive changes.

Aymeric Augustin 69039becde Deprecated get_app(). 2013-12-17 10:17:45 +01:00
Aymeric Augustin 2732edc5f2 Deprecated get_apps(). 2013-12-17 10:17:45 +01:00
Aymeric Augustin d44de9b933 Removed the _-prefix for populate().
Several parts of Django call get_apps() with a comment along this lines
of "this has the side effect of calling _populate()". I fail to see how
this is better than just calling populate()!
2013-12-17 10:17:45 +01:00
Aymeric Augustin ebda5800ae Simplified register_models.
Since it's never called with more than one model at a time the current
signature is needlessly complicated.
2013-12-17 10:17:45 +01:00
Aymeric Augustin 259cd3cd41 Deprecated get_app_package, get_app_path and get_app_paths. 2013-12-17 10:17:45 +01:00
Aymeric Augustin 2c9e84af4a Removed unused attribute app_errors of the app cache.
get_app_errors() always returned an empty dictionary; this behavior is
preserved in django.db.models.loading until that module is deprecated.
2013-12-17 10:17:44 +01:00
Aymeric Augustin 8662654d6d Removed module-level functions for the app cache.
Since the original ones in django.db.models.loading were kept only for
backwards compatibility, there's no need to recreate them. However, many
internals of Django still relied on them.

They were also imported in django.db.models. They never appear in the
documentation, except a quick mention of get_models and get_app in the
1.2 release notes to document an edge case in GIS. I don't think that
makes them a public API.

This commit doesn't change the overall amount of global state but
clarifies that it's tied to the app_cache object instead of hiding it
behind half a dozen functions.
2013-12-17 10:17:44 +01:00
Aymeric Augustin 860c2c8bc5 Moved django.db.models.loading to django.apps.cache.
This commit doesn't contain any code changes; it's purely a refactoring.

Loic Bistuer 17c3997f68 Fixed #21169 -- Reworked RelatedManager methods use default filtering
The `remove()` and `clear()` methods of the related managers created by
`ForeignKey`, `GenericForeignKey`, and `ManyToManyField` suffered from a
number of issues. Some operations ran multiple data modifying queries without
wrapping them in a transaction, and some operations didn't respect default
filtering when it was present (i.e. when the default manager on the related
model implemented a custom `get_queryset()`).

Fixing the issues introduced some backward incompatible changes:

- The implementation of `remove()` for `ForeignKey` related managers changed
  from a series of `Model.save()` calls to a single `QuerySet.update()` call.
  The change means that `pre_save` and `post_save` signals aren't called anymore.

- The `remove()` and `clear()` methods for `GenericForeignKey` related
  managers now perform bulk delete so `Model.delete()` isn't called anymore.

- The `remove()` and `clear()` methods for `ManyToManyField` related
  managers perform nested queries when filtering is involved, which may
  or may not be an issue depending on the database and the data itself.

Refs. #3871, #21174.

Thanks Anssi Kääriäinen and Tim Graham for the reviews.

Loic Bistuer f51c1f5900 Fixed #17001 -- Custom querysets for prefetch_related.
This patch introduces the Prefetch object which allows customizing prefetch
operations.

This enables things like filtering prefetched relations, calling select_related
from a prefetched relation, or prefetching the same relation multiple times
with different querysets.

When a Prefetch instance specifies a to_attr argument, the result is stored
in a list rather than a QuerySet. This has the fortunate consequence of being
significantly faster. The preformance improvement is due to the fact that we
save the costly creation of a QuerySet instance.

Thanks @akaariai for the original patch and @bmispelon and @timgraham
for the reviews.

Anssi Kääriäinen 6fe2b001db Fixed #21376 -- New implementation for query join promotion logic
This commit introduced a new class JoinPromoter that can be used to
abstract away join promotion problems for complex filter conditions.
Query._add_q() and Query.combine() now use the new class.

Also, added a lot of comments about why join promotion is done the way
it is.

Thanks to Tim Graham for original report and testing the changes, and
for Loic Bistuer for review.
