2020-06-10Fixed #31680 -- Removed unnecessary getattr() call in ↵alosultan

2020-01-29Simplified DeferredAttribute.__get__() a bit.Taoup
2019-12-06Fixed #31060 -- Reallowed window expressions to be used in conditions ↵Alex Aktsipetrov
outside of queryset filters. Regression in 4edad1ddf6203326e0be4bdb105beecb0fe454c4. Thanks utapyngo for the report.
2019-11-18Fixed #30988 -- Deprecated the InvalidQuery exception.Simon Charette
It was barely documented without pointers at its defining location and was abused to prevent misuse of the QuerySet field deferring feature.
2019-11-18Replaced QueryWrapper single usage with RawSQL.Simon Charette
2019-10-01Fixed #30651 -- Made __eq__() methods return NotImplemented for not ↵ElizabethU
implemented comparisons. Changed __eq__ to return NotImplemented instead of False if compared to an object of the same type, as is recommended by the Python data model reference. Now these models can be compared to ANY (or other objects with __eq__ overwritten) without returning False automatically.

2017-12-08Refs #27849 -- Removed empty Q() hack in filtered Aggregate.as_sql().Simon Charette
This required allowing WhereNode to be provided as When(condition). This was made possible by cf12257db23fa248c89a3da3f718aa01a50ca659.
2017-09-22Fixed #27332 -- Added FilteredRelation API for conditional join (ON clause) ↵Nicolas Delaby

2015-06-29Fixed #23791 -- Corrected object type check for pk__in=qsAnssi Kääriäinen
When the pk was a relation field, qs.filter(pk__in=qs) didn't work. In addition, fixed Restaurant.objects.filter(place=restaurant_instance), 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.
2015-06-05Fixed #24924 -- Join promotion for multiple Case expressionsMark Lavin

2015-04-18Removed cases of six.iter* wrapped in a list()Curtis Maloney
There's absolutely no advantage [and a mild performance hit] to using six.iter* in these cases.
2015-03-25Renamed Field.rel attribute to remote_fieldAnssi Kääriäinen
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.
2015-03-25Refs #24267 -- Implemented lookups for related fieldsAnssi Kääriäinen
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().
2015-02-06Sorted imports with isort; refs #23860.Tim Graham
2015-02-04Fixed #24268 -- removed Query.havingAnssi Kääriäinen
Instead of splitting filter clauses to where and having parts before adding them to query.where or query.having, add all filter clauses to query.where, and when compiling the query split the where to having and where parts.
2015-01-15Replaced inner functions by class methods.Simon Charette
refs #24031 Thanks to Tim Graham and Michał Modzelewski for the review.
2015-01-12Fixed #24031 -- Added CASE expressions to the ORM.Michał Modzelewski
2015-01-08Fixed #24020 -- Refactored SQL compiler to use expressionsAnssi Kääriäinen
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.
