156a2138db Refs #30446 -- Removed unnecessary Value(..., output_field) in docs and tests. 2020-07-15 10:58:38 +02:00
Simon Charette
1e38f1191d Fixed #30446 -- Resolved Value.output_field for stdlib types. 
This required implementing a limited form of dynamic dispatch to combine
expressions with numerical output. Refs #26355 should eventually provide
a better interface for that.

720de4d044 Fixed #31109 -- Disabled grouping by aliases on QuerySet.exists(). 
Clearing the SELECT clause in Query.has_results was orphaning GROUP BY
references to it.

bisect.

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.
