Andrew Godwin 86e69bf3b6 Fixed #21785: Bad handling of both auto_now and _add on deconstruct 2014-01-17 10:46:03 +00:00
Andrew Godwin 7535e9f4a4 Fixed #21784: Correctly decode stdin input for migration defaults 2014-01-16 19:04:10 +00:00
Aymeric Augustin d562527a16 Fixed #21477 -- Renamed db to using in pre/post_migrate signals. 2014-01-12 22:24:33 +01:00
Aymeric Augustin fbe1abac4a Fixed #21453 -- Enabled autocommit before calling init_connection_state.
Also ensured the transaction state is clean on Oracle while I was there.

This change cannot be backported to 1.6 because it's
backwards-incompatible for custom database backends.

Aymeric Augustin 1afe748832 Fixed #21452 -- Non-autocommit connections to PostgreSQL.
When settings.DATABASES['default']['AUTOCOMMIT'] = False, the connection
wasn't in autocommit mode but Django pretended it was.

Thanks Anssi for analysing this issue.

Aymeric Augustin 75220d3b5d Small style cleanup. 2013-12-31 16:24:40 +01:00
Aymeric Augustin 80004c7cc0 Turned django.db.models.app_cache_ready back into a method.
Thanks Anssi for noticing this mistake in a refactoring.
2013-12-31 15:27:25 +01:00
Aymeric Augustin bfcc686d22 Removed the only_with_models_module argument of get_model[s].
Now that the refactorings are complete, it isn't particularly useful any
more, nor very well named. Let's keep the API as simple as possible.

Fixed #21689.
2013-12-30 23:59:34 +01:00
Aymeric Augustin 80d74097b4 Stopped populating the app registry as a side effect.
Since it triggers imports, it shouldn't be done lightly.

This commit adds a public API for doing it explicitly, django.setup(),
and does it automatically when using manage.py and wsgi.py.
2013-12-30 22:11:17 +01:00
Aymeric Augustin 7ed20e0153 Populated Apps instances immediately by default. 2013-12-30 22:11:17 +01:00
Aymeric Augustin 856aaaf2b1 Changed get_migratable_models to use an app config. 2013-12-29 21:25:28 +01:00
Aymeric Augustin 20d487c27b Replaced Options.object_name.lower() by Options.model_name.
Thanks Simon for the suggestion.

Also removed inappropriate lowercasing of app labels in migrations.
Unlike model names, they are case sensitive.
2013-12-29 18:48:37 +01:00
Aymeric Augustin 00110904ac Refactored the migration signals to use app configs.
De-aliased pre/post_syncdb to pre/post_migrate to increase
backwards-compatibility.
2013-12-29 17:53:42 +01:00
Ramiro Morales 5782c94f23 Added generation of SQLite FK DDL in initial migrations.
SQLite accepts the relevant standard SQL (although by default it doesn't
enforce the constraint), and the 'traditional' creation backend helper
generate it, so this allows us to:

- Maintain the status quo
- Improve readability of the SQL code generated for that backend.

Also, we will need this for when we fix Refs #14204.

Aymeric Augustin 9f13c33281 Removed the only_installed argument of Apps.get_models.
Refs #15903, #15866, #15850.
2013-12-28 20:54:26 +01:00
Aymeric Augustin ba7206cd81 Changed get_model to raise an exception on errors.
Returning None on errors required unpythonic error checking and was
inconsistent with get_app_config.

get_model was a private API until the previous commit, but given that it
was certainly used in third party software, the change is explained in
the release notes.

Applied the same change to get_registered_model, which is a new private
API introduced during the recent refactoring.
2013-12-28 20:53:00 +01:00
Aymeric Augustin 81354b82bf Stopped calling apps.get_model with only_installed=False.
ContentTypes are only created for installed applications, and I could
make a case for not returning a model that isn't installed any more.
The check for stale ContentTypes in update_contenttypes doesn't use
model_class.

ModelSignal actually needs get_registered_model since the lookup happens
at import time. I took this opportunity to perform a small refactoring.
2013-12-28 20:42:58 +01:00
Aymeric Augustin bbdf01e00a Populated non-master app registries.
This removes the gap between the master app registry and ad-hoc app
registries created by the migration framework, specifically in terms
of behavior of the get_model[s] methods.

This commit contains a stealth feature that I'd rather not describe.
2013-12-28 20:37:42 +01:00
Ramiro Morales 6a6136141b Implemented #10164 for new schema migration code.
Made it use 'AUTOINCREMENT' suffix for PK creation. This way it doeesn't
regress when compared with the 'traditional' DB backend creation
infrastructure.

Refs #10164.
2013-12-28 11:21:01 -03:00
Aymeric Augustin c81fae6b95 Used app_label instead of appname.
The last component of the dotted path to the application module is
consistently referenced as the application "label". For instance it's
AppConfig.label. appname could be confused with AppConfig.name, which is
the full dotted path.
2013-12-28 09:53:02 +01:00
Ramiro Morales 3efd1b8b93 Fixed #21692 -- Quote table name when creating it. 2013-12-27 18:43:52 -03:00
Aymeric Augustin 2504a50cc2 Created a constant for the migrations module name.
Mostly for consistency with MODELS_MODULE_NAME; it's unlikely to change.
2013-12-27 15:36:19 +01:00
Aymeric Augustin 52325b0a04 Turned apps.ready into a property. Added tests. 2013-12-26 15:04:58 +01:00
Aymeric Augustin 8f04f53dd8 Removed a few gratuitous lambdas. 2013-12-26 14:03:50 +01:00

Jonas Gastal 96967f642f Typo fix for exception message. 2013-12-24 14:26:50 -02:00
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().
2013-12-24 12:25:17 +01:00
Aymeric Augustin 17c66e6fe7 Renamed has_model to get_registered_models.
That matches its return type better.
2013-12-22 17:08:17 +01:00
Aymeric Augustin 2fef9e5375 Moved apps back in the toplevel django namespace.
Reverted 4a56a93cc4.
2013-12-22 11:39:55 +01:00
Aymeric Augustin 70c9654d45 Renamed registered_model to has_model.
This avoids possible confusion with register_model.

Thanks Marc Tamlyn for the suggestion.
2013-12-22 11:39:18 +01:00
Aymeric Augustin 439b364e1e Added an _-prefix to pending lookups because it's transient. 2013-12-22 11:39:17 +01:00
Aymeric Augustin 86804ab063 Terminated AppCache._populate() with extreme prejudice.
It was called _populate() before I renamed it to populate(). Since it
has been superseded by populate_models() there's no reason to keep it.

Removed the can_postpone argument of load_app() as it was only used by
populate(). It's a private API and there's no replacement. Simplified
load_app() accordingly. Then new version behaves exactly like the old
one even though it's much shorter.
2013-12-22 11:39:17 +01:00
Aymeric Augustin 9b3389b726 Removed the app_config.installed flag.
Since applications that aren't installed no longer have an application
configuration, it is now always True in practice.

Provided an abstraction to temporarily add or remove applications as
several tests messed with app_config.installed to achieve this effect.
For now this API is _-prefixed because it looks dangerous.
2013-12-22 11:39:17 +01:00
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.
2013-12-22 11:39:17 +01:00
Alexey Voronov 7f2485b4d1 Fixed #21643 -- repeated execution of qs with F() + timedelta
Thanks Tim Graham for review.
2013-12-22 00:03:17 +02:00
Baptiste Mispelon f1b3ab9c21 Fixed #11629 -- Deprecated callable arguments to queryset methods.
Callable arguments were an untested and undocumented feature.
2013-12-18 18:40:00 +01:00
Denis Moskalets d4e578d0f6 Fixed #21552 -- Allowed the use of None for the iexact lookup.
Thanks Anubhav Joshi for the documentation.
2013-12-18 09:34:53 -05:00
Aymeric Augustin 7eea9bf303 Normalized Model._meta.installed.
Used the information from the app cache instead of creating a duplicate
based on INSTALLED_APPS.

Model._meta.installed is no longer writable. It was a rather sketchy way
to alter private internals anyway.
2013-12-17 21:55:16 +01:00
Aymeric Augustin 0242c56fd8 Deborgified the app cache.
Improved Andrew's hack to create temporary app caches to handle
migrations. Now the main app cache has a "master" flag set to True
(which is a non-default keyword argument, thus unlikely to be used by
mistake). Other app cache instances have "master" set to False.

The only sanctioned way to access the app cache is by importing
django.core.apps.app_cache.

If you were instanciating an app cache and relying on the Borg pattern,
you'll have to refactor your code.
2013-12-17 21:53:18 +01:00
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.
2013-12-17 10:17:46 +01:00
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.
