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.

Akshesh 6a8372e6ec Fixed #26808 -- Added Meta.indexes for class-based indexes.
* Added the index name to its deconstruction.

Marti Raudsepp b9ae662c97 Fixed #26620 -- Made Model.refresh_from_db() fail when passed unknown kwargs. 2016-05-18 09:27:23 -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.

Loïc Bistuer 3a47d42fa3 Fixed #20932, #25897 -- Streamlined manager inheritance. 2016-05-17 02:29:22 +07:00
Aron Podrigal 85ef98dc6e Fixed #24305 -- Allowed overriding fields on abstract models.
Fields inherited from abstract base classes may be overridden like
any other Python attribute. Inheriting from multiple models/classes
with the same attribute name will follow the MRO.

Michal Petrucha 8a47ba679d Refs #16508 -- Made Model.__init__() aware of virtual fields.
It's no longer necessary for GenericForeignKey (and any other virtual fields)
to intercept the field's values using the pre_init signal.

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.

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.
