Using select_related() after .values() or .values_list() is not possible

Anssi Kääriäinen 9ed82154bd Fixed #23791 -- Corrected object type check for pk__in=qs
When the pk was a relation field, qs.filter(pk__in=qs) didn't work.

where place is an OneToOneField and the primary key of Restaurant.

A big thank you to Josh for review and to Tim for review and cosmetic
edits.

Thanks to Beauhurst for commissioning the work on this ticket.

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
Marc Tamlyn 4755f8fc25 Fixed #24343 -- Ensure db converters are used for foreign keys.

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.
2015-02-03 09:23:44 -05:00
Tim Graham 293fd5da5b Reverted "Fixed #6785 -- Made QuerySet.get() fetch a limited number of rows."
This reverts commit da79ccca1d.

This optimized the unsuccessful case at the expense of the successful one.

2015-01-22 00:44:14 +07:00
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.
2015-01-08 14:07:54 -05:00
Daniel Pyrathon fb48eb0581 Fixed #12663 -- Formalized the Model._meta API for retrieving fields.

database converters APIs.
2014-11-26 17:49:25 -05:00

Thomas Chaumeny b962653060 Fixed #23664 -- Provided a consistent definition for OrderedSet.__bool__
This also defines QuerySet.__bool__ for consistency though this should not have any consequence as bool(qs) used to fallback on QuerySet.__len__ in Py3.
2014-10-16 14:16:24 +02:00
Claude Paroz 374c14b7fd Fixed #23659 -- Kept annotate() args ordering

Marc Tamlyn e9103402c0 Fixed #18757, #14462, #21565 -- Reworked database-python type conversions
Complete rework of translating data values from database

Deprecation of SubfieldBase, removal of resolve_columns and
convert_values in favour of a more general converter based approach and
public API Field.from_db_value(). Now works seamlessly with aggregation,
.values() and raw queries.

Thanks to akaariai in particular for extensive advice and inspiration,
also to shaib, manfre and timograham for their reviews.

Thanks Michael Miller for reporting the issue.
2014-08-05 03:12:08 +03:00
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!
2014-07-01 16:31:01 +03:00
Anubhav Joshi 42736ac8e8 Fixed #21430 -- Added a RuntimeWarning when unpickling Models and QuerySets from a different Django version.
