Anssi Kääriäinen 20bab2cf9d Fixed #16187 -- refactored ORM lookup system

are available for fields. The implementation is now class based.

    Merge pull request #2 from mjtamlyn/lookups_3

    Reworked custom lookups docs.

commit f2dc4429a1
Author: Marc Tamlyn <marc.tamlyn@gmail.com>
Date:   Sun Jan 12 13:15:05 2014 +0000

    Reworked custom lookups docs.

    Mostly just formatting and rewording, but also replaced the example
    using ``YearExtract`` to  use an example which is unlikely to ever be
    possible directly in the ORM.

commit c7d5f8661b
Author: Anssi Kääriäinen <akaariai@gmail.com>
Date:   Sat Jan 11 14:45:53 2014 +0200

    Altered query string customization for backends vendors

    The new way is trying to call first method 'as_' + connection.vendor.
    If that doesn't exist, then call as_sql().

    Also altered how lookup registration is done. There is now
    RegisterLookupMixin class that is used by Field, Extract and
    sql.Aggregate. This allows one to register lookups for extracts and
    aggregates in the same way lookup registration is done for fields.

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 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.

Baptiste Mispelon 621c25c419 Added missing deconstruct() methods. 2013-12-06 15:23:34 +01:00
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.

Tim Graham 36ded01527 Fixed #21302 -- Fixed unused imports and import *. 2013-11-02 15:24:56 -04:00
Loic Bistuer 31fadc1202 Fixed #20625 -- Chainable Manager/QuerySet methods.
Additionally this patch solves the orthogonal problem that specialized
`QuerySet` like `ValuesQuerySet` didn't inherit from the current `QuerySet`
type. This wasn't an issue until now because we didn't officially support
custom `QuerySet` but it became necessary with the introduction of this new
feature.

Thanks aaugustin, akaariai, carljm, charettes, mjtamlyn, shaib and timgraham
for the reviews.

Alex Gaynor 03d9566e0d A large number of stylistic cleanups across django/db/ 2013-07-08 10:39:54 +10:00
Aymeric Augustin 4daf570b98 Added TransactionTestCase.available_apps.
This can be used to make Django's test suite significantly faster by
reducing the number of models for which content types and permissions
must be created and tables must be flushed in each non-transactional
test.

It's documented for Django contributors and committers but it's branded
as a private API to preserve our freedom to change it in the future.

Most of the credit goes to Anssi. He got the idea and did the research.

Fixed #20483.
2013-06-10 11:24:10 +02:00
Aymeric Augustin b55624a026 Added get_app_paths() to the AppCache.

Gary Wilson Jr c2ba59fc1d Removed oldforms, validators, and related code:
* Removed `Manipulator`, `AutomaticManipulator`, and related classes.
 * Removed oldforms specific bits from model fields:
   * Removed `validator_list` and `core` arguments from constructors.
   * Removed the methods:
     * `get_manipulator_field_names`
     * `get_manipulator_field_objs`
     * `get_manipulator_fields`
     * `get_manipulator_new_data`
     * `prepare_field_objs_and_params`
     * `get_follow`
   * Renamed `flatten_data` method to `value_to_string` for better alignment with its use by the serialization framework, which was the only remaining code using `flatten_data`.
 * Removed oldforms methods from `django.db.models.Options` class: `get_followed_related_objects`, `get_data_holders`, `get_follow`, and `has_field_type`.
 * Removed oldforms-admin specific options from `django.db.models.fields.related` classes: `num_in_admin`, `min_num_in_admin`, `max_num_in_admin`, `num_extra_on_change`, and `edit_inline`.
 * Serialization framework
   * `Serializer.get_string_value` now calls the model fields' renamed `value_to_string` methods.
   * Removed a special-casing of `models.DateTimeField` in `core.serializers.base.Serializer.get_string_value` that's handled by `django.db.models.fields.DateTimeField.value_to_string`.
 * Removed `django.core.validators`:
   * Moved `ValidationError` exception to `django.core.exceptions`.
   * For the couple places that were using validators, brought over the necessary code to maintain the same functionality.
 * Introduced a SlugField form field for validation and to compliment the SlugField model field (refs #8040).
 * Removed an oldforms-style model creation hack (refs #2160).
