Thanks to Mads Jenson for review.
 2019-10-02 15:50:46 +02:00
ElizabethU 54ea290e5b Fixed #30651 -- Made __eq__() methods return NotImplemented for not 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.
 2019-10-01 17:58:19 +02:00
Matthew Schinckel 4137fc2efc Fixed #25367 -- Allowed boolean expressions in QuerySet.filter() and exclude(). 
This allows using expressions that have an output_field that is a
BooleanField to be used directly in a queryset filters, or in the
When() clauses of a Case() expression.

Thanks Josh Smeaton, Tim Graham, Simon Charette, Mariusz Felisiak, and
Adam Johnson for reviews.

Mariusz Felisiak 362813d628
Fixed hanging indentation in various code. 2018-03-16 10:54:34 +01:00
Simon Charette 277ed07209 Fixed #29195 -- Fixed Exists.output_field resolution on single-valued queries. 
The Subquery class which Exists inherits from defaulted to using single-valued
querie's field if no output_field was explicitly specified on initialization
which was bypassing the Exists.output_field defined at the class level.

Moving Subquery's dynamic output_field resolution to _resolve_output_field
should make sure the fallback logic is only performed if required.

Regression in 08654a99bb.

Thanks Oli Warner for the detailed report.

and made sure .values().distinct().aggreate() works correctly.
