Adam Chainz d2a26c1a90 Optimized Model instantiation a bit.
* Avoid some unnecessary attribute lookups, e.g. access signals directly rather than from module
* Alias some repeat accesses inside the method to use the slightly faster local lookups
* Use tuple to iterate remaining kwargs as it's faster to construct
* Cache Field.get_default() to avoid running through all the logic on every call
* Use a cached list of the properties on the model class to avoid repeat isinstance() calls

Adam Chainz 6252fd6314 Fixed #27532 -- Deprecated Model._meta.has_auto_field 2016-11-25 13:24:11 -05:00
Adam Chainz 92bbef8b9e Improved the way Model.save() skips the auto_field.
Identity comparison is quicker than isinstance(), and it avoids coupling
between Model and AutoField.

This deprecates use_for_related_fields.

Old API:

    custom_manager = CustomManager()

New API:

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

    class Meta:
        base_manager_name = 'custom_manager'

Aron Podrigal 85ef98dc6e Fixed #24305 -- Allowed overriding fields on abstract models.

Michal Petrucha 8a47ba679d Refs #16508 -- Made Model.__init__() aware of virtual fields.

Anssi Kääriäinen 7f51876f99 Fixed #26207 -- Replaced dynamic classes with non-data descriptors for deferred instance loading. 2016-04-29 13:06:32 -04:00
Michal Petrucha c339a5a6f7 Refs #16508 -- Renamed the current "virtual" fields to "private".
The only reason why GenericForeignKey and GenericRelation are stored
separately inside _meta is that they need to be cloned for every model
subclass, but that's not true for any other virtual field. Actually,
it's only true for GenericRelation.

Alex Hill 720ff740e7 Fixed #24215 -- Refactored lazy model operations
This adds a new method, Apps.lazy_model_operation(), and a helper function,
lazy_related_operation(), which together supersede add_lazy_relation() and
make lazy model operations the responsibility of the App registry. This
system no longer uses the class_prepared signal.
2015-03-25 16:48:17 -04:00
Anssi Kääriäinen 8f30556329 Renamed Field.rel attribute to remote_field
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Loic Bistuer bed504d70b Fixed #24351, #24346 -- Changed the signature of allow_migrate().
The new signature enables better support for routing RunPython and
RunSQL operations, especially w.r.t. reusable and third-party apps.

This commit also takes advantage of the deprecation cycle for the old
signature to remove the backward incompatibility introduced in #22583;
RunPython and RunSQL won't call allow_migrate() when when the router
has the old signature.

Thanks Aymeric Augustin and Tim Graham for helping shape up the patch.

Anssi Kääriäinen 8adc59038c Fixed #23617 -- Added get_pk_value_on_save()
The method is mainly intended for use with UUIDField. For UUIDField we
want to call the field's default even when primary key value is
explicitly set to None to match the behavior of AutoField.

Thanks to Marc Tamlyn and Tim Graham for review.

Anssi Kääriäinen 0b6f05ede6 Fixed #19501 -- added Model.from_db() method
The Model.from_db() is intended to be used in cases where customization
of model loading is needed. Reasons can be performance, or adding custom
behavior to the model (for example "dirty field tracking" to issue
automatic update_fields when saving models).

A big thank you to Tim Graham for the review!
