Nicolas Delaby 01d440fa1e Fixed #27332 -- Added FilteredRelation API for conditional join (ON clause) support.

Maxime Lorant 5153a3bfdc Fixed #25331 -- Removed trailing blank lines in docstrings. 2015-08-31 17:37:21 -04:00
Alex Hill 98bcdfa8bd Fixed #25064 -- Allowed empty join columns. 2015-08-15 07:26:44 -04:00
Anssi Kääriäinen f233bf47dd Fixed #21414 -- Removed RelatedObject and deprecated Field.related. 2014-12-23 10:54:25 -05:00
Anssi Kääriäinen ab89414f40 Fixed #23853 -- Added Join class to replace JoinInfo
Also removed Query.join_map. This structure was used to speed up join
reuse calculation. Initial benchmarking shows that this isn't actually
needed. If there are use cases where the removal has real-world
performance implications, it should be relatively straightforward to
reintroduce it as map {alias: [Join-like objects]}.

commit f2dc4429a1
Author: Marc Tamlyn <marc.tamlyn@gmail.com>
Date:   Sun Jan 12 13:15:05 2014 +0000

    Reworked custom lookups docs.

    Mostly just formatting and rewording, but also replaced the example
    using ``YearExtract`` to  use an example which is unlikely to ever be
    possible directly in the ORM.

commit c7d5f8661b
Author: Anssi Kääriäinen <akaariai@gmail.com>
Date:   Sat Jan 11 14:45:53 2014 +0200

    Altered query string customization for backends vendors

    The new way is trying to call first method 'as_' + connection.vendor.
    If that doesn't exist, then call as_sql().

    Also altered how lookup registration is done. There is now
    RegisterLookupMixin class that is used by Field, Extract and
    sql.Aggregate. This allows one to register lookups for extracts and
    aggregates in the same way lookup registration is done for fields.

Anssi Kääriäinen d744c550d5 Fixed #19964 -- Removed relabel_aliases from some structs

many structs. Now there is only relabeled_clone() for those structs
where alias is the only mutable attribute.

Anssi Kääriäinen b4492a8ca4 Fixed #19837 -- Refactored split_exclude() join generation
The refactoring mainly concentrates on making sure the inner and outer
query agree about the split position. The split position is where the
multijoin happens, and thus the split position also determines the
columns used in the "WHERE col1 IN (SELECT col2 from ...)" condition.

This commit fixes a regression caused by #10790 and commit
69597e5bcc. The regression was caused
by wrong cols in the split position.

Anssi Kääriäinen bd283aa844 Refactored the empty/full result logic in WhereNode.as_sql()
Made sure the WhereNode.as_sql() handles various EmptyResultSet and
FullResultSet conditions correctly. Also, got rid of the FullResultSet
exception class. It is now represented by '', [] return value in the
as_sql() methods.
