Aymeric Augustin e542e81b39 Renamed descriptor classes for related objects.
The old names were downright confusing. Some seemed to mean the opposite
of what the class actually did.

The new names follow a consistent nomenclature:

    (Forward|Reverse)(ManyToOne|OneToOne|ManyToMany)Descriptor.

I mentioned combinations that do not exist in the docstring in order to
help people who would search for them in the code base.

Aymeric Augustin 005c9fc45f Fixed #22341 -- Split django.db.models.fields.related.

Very small changes were performed to uniformize import style.

Aymeric Augustin c3904deb91 Fixed #25160 (again) -- Moved data loss check on reverse relations.

e4b813c but for reverse relations.

and with related_name set to '+'.
2015-03-26 19:00:37 -04:00
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.
2015-03-25 08:16:12 -04:00
Anssi Kääriäinen f9c70bb3a1 Renamed ForeignObject.related_field to target_field 2015-03-25 08:13:27 -04:00

Anssi Kääriäinen b68212f539 Refs #24267 -- Implemented lookups for related fields
Previously related fields didn't implement get_lookup, instead
related fields were treated specially. This commit removed some of
the special handling. In particular, related fields return Lookup
instances now, too.

Other notable changes in this commit is removal of support for
annotations in names_to_path().

Karl Hobley 81e1a35c36 Fixed #24495 -- Allowed unsaved model instance assignment check to be bypassed. 2015-03-18 19:00:09 -04:00
Anssi Kääriäinen f95122e541 Fixed #24381 -- removed ForeignObjectRel opts and to_opts
These cached properies were causing problems with pickling, and in
addition they were confusingly defined: field.rel.model._meta was
not the same as field.rel.opts.

Instead users should use field.rel.related_model._meta inplace of
field.rel.opts, and field.rel.to._meta in place of field.rel.to_opts.
2015-02-23 07:24:43 -05:00
Marc Tamlyn 32d4db66b9 Update converters to take a consistent set of parameters.
As suggested by Anssi. This has the slightly strange side effect of
passing the expression to Expression.convert_value has the expression
passed back to it, but it allows more complex patterns of expressions.
2015-02-20 11:35:52 +00:00
Marc Tamlyn 4755f8fc25 Fixed #24343 -- Ensure db converters are used for foreign keys.

Loic Bistuer 20eb51ce0d Fix small regression caused by 71ada3a8e6.
During direct assignment, evaluating the iterable before the transaction
is started avoids leaving the transaction dirty if an exception is raised.
This is slightly more wasteful but probably not enough to warrant a change
of behavior.

Thanks Anssi for the feedback. Refs #6707.
2015-02-05 16:59:56 +07:00
Loic Bistuer 71ada3a8e6 Fixed #6707 -- Added RelatedManager.set() and made descriptors' __set__ use it.

Loïc for the test name and Tim for the review.

Anssi Kääriäinen 0c7633178f Fixed #24020 -- Refactored SQL compiler to use expressions
Refactored compiler SELECT, GROUP BY and ORDER BY generation.
While there, also refactored select_related() implementation
(get_cached_row() and get_klass_info() are now gone!).

Made get_db_converters() method work on expressions instead of
internal_type. This allows the backend converters to target
specific expressions if need be.

Added query.context, this can be used to set per-query state.

Also changed the signature of database converters. They now accept
context as an argument.

Loic Bistuer 20399083f4 Fixed #19816 -- Pre-evaluate querysets used in direct relation assignments.
Since assignments on M2M or reverse FK descriptors is composed of a `clear()`,
followed by an `add()`, `clear()` could potentially affect the value of the
assigned queryset before the `add()` step; pre-evaluating it solves the problem.

This patch fixes the issue for ForeignRelatedObjectsDescriptor,
ManyRelatedObjectsDescriptor, and ReverseGenericRelatedObjectsDescriptor.
It completes 6cb6e1 which addressed ReverseManyRelatedObjectsDescriptor.
