Julien Hartmann f4afb85d7e Fixed #26749 -- Preserved behavior of use_for_related_field during deprecation. 2016-07-11 13:30:44 -04:00
Loïc Bistuer ed0ff913c6 Fixed #10506, #13793, #14891, #25201 -- Introduced new APIs to specify models' default and base managers.
This deprecates use_for_related_fields.

Old API:

class CustomManager(models.Model):
    use_for_related_fields = True

class Model(models.Model):
    custom_manager = CustomManager()

New API:

class Model(models.Model):
    custom_manager = CustomManager()

    class Meta:
        base_manager_name = 'custom_manager'

Refs #20932, #25897.

Thanks Carl Meyer for the guidance throughout this work.
Thanks Tim Graham for writing the docs.

Simon Charette eb4cdfbdd6 Fixed #23940 -- Allowed model fields to be named `exact`.
An explicit `__exact` lookup in the related managers filters
was interpreted as a reference to a foreign `exact` field.

Aymeric Augustin 38ce41103f Used Apps.clear_cache() in tests that alter the app registry. 2013-12-29 21:25:28 +01:00
Aymeric Augustin 1716b7ce5a Renamed AppCache to Apps.
Also renamed app_cache to apps and "app cache" to "app registry".

Deprecated AppCache.app_cache_ready() in favor of Apps.ready().

Aymeric Augustin 82a35e24d4 Replaced ad-hoc caching of get_models with lru_cache.
Invalidate properly the cache whenever all_models or app_configs change.
This fixes some isolation issues in the test suite.

Aymeric Augustin e32095616c Imported override_settings from its new location. 2013-12-23 21:37:56 +01:00
Aymeric Augustin 2fef9e5375 Moved apps back in the toplevel django namespace.
Reverted 4a56a93cc4.

Aymeric Augustin 742ed9878e Refactored registration of models.
Got rid of AppConfig._stub. As a side effect, app_cache.app_configs now
only contains entries for applications that are in INSTALLED_APPS, which
is a good thing and will allow dramatic simplifications (which I will
perform in the next commit). That required adjusting all methods that
iterate on app_configs without checking the "installed" flag, hence the
large changes in get_model[s].

Introduced AppCache.all_models to store models:
- while the app cache is being populated and a suitable app config
  object to register models isn't available yet;
- for applications that aren't in INSTALLED_APPS since they don't have
  an app config any longer.

Replaced get_model(seed_cache=False) by registered_model() which can be
kept simple and safe to call at any time, and removed the seed_cache
argument to get_model[s]. There's no replacement for that private API.

Allowed non-master app caches to go through populate() as it is now
safe to do so. They were introduced in 1.7 so backwards compatibility
isn't a concern as long as the migrations framework keeps working.

Aymeric Augustin 4a56a93cc4 Moved the new app cache inside core. 2013-12-17 10:17:46 +01:00
Aymeric Augustin b55282b98b Moved list of models inside AppConfig instances.
This commit is a refactoring with no change of functionality, according
to the following invariants:

- An app_label that was in app_configs and app_models stays in
  app_config and has its 'installed' attribute set to True.

- An app_label that was in app_models but not in app_configs is added to
  app_configs and has its 'installed' attribute set to True.

As a consequence, all the code that iterated on app_configs is modified
to check for the 'installed' attribute. Code that iterated on app_models
is rewritten in terms of app_configs.

Many tests that stored and restored the state of the app cache were
updated.

In the long term, we should reconsider the usefulness of allowing
importing models from non-installed applications. This doesn't sound
particularly useful, can be a trap in some circumstances, and causes
significant complexity in sensitive areas of Django.

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.

Aymeric Augustin 9217b89da3 Removed BaseAppCache.app_store.
It was only storing redundant information. This is part of the effort to
allow applications without a models module.
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.
