Étienne Beaulé 509d9da26f Fixed #26390 -- Disabled grouping by Random(). 
Thanks to Tzu-ping Chung for the tests.
 2020-10-21 20:54:53 +02:00
David Wobrock 058747b77a Fixed #31880 -- Made QuerySet.aggregate() raise FieldError when aggregating over aggregation aliases. 2020-09-29 09:04:25 +02:00
Ahmad A. Hussein 493b26bbfc Fixed #31888 -- Avoided module-level MySQL queries in tests. 2020-08-17 09:31:16 +02:00
Simon Charette 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.

Simon Charette adfbf653dc Fixed #31568 -- Fixed alias reference when aggregating over multiple subqueries. 
691def10a0 made all Subquery() instances
equal to each other which broke aggregation subquery pushdown which
relied on object equality to determine which alias it should select.

Subquery.__eq__() will be fixed in an another commit but
Query.rewrite_cols() should haved used object identity from the start.

Refs #30727, #30188.

Thanks Makina Corpus for the report.

CruxBox 34f8eeea4a Fixed #30548 -- Improved exception when expression contains mixed types. 2019-06-10 19:48:53 +02:00
Étienne Beaulé 4b6dfe1622 Fixed #30542 -- Fixed crash of numerical aggregations with filter. 
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.

Thanks to Chuan-Zheng Lee for the report.

Regression in c690afb873 and two following
commits.
