2017-05-11Fixed #24254 -- Fixed queries using the __in lookup with querysets using ↵Simon Charette
distinct() and order_by(). Thanks Tim for the review.
2017-05-11Fixed #28107 -- Disabled grouping of selected primary keys for unmanaged models.Simon Charette
The grouping caused an issue with database views as PostgreSQL's query planer isn't smart enough to introspect primary keys through views. Django doesn't support database views but documents that unmanaged models should be used to query them. Thanks powderflask for the detailed report and investigation.
2017-05-01Refs #16187 -- Stopped compiling query compilers during lookup rhs processing.Simon Charette
Lookup right hand side processing was compiling query compilers which happened to work by chance as SQLCompiler defines a as_sql() method with two optional parameters albeit it doesn't expect the same type of arguments.
2017-04-28Reverted "Refs #20939 -- Moved subquery ordering clearing optimization to ↵Simon Charette
the __in lookup." This reverts commit e62ea0bb9cbb54c1eef848871fe3eab2bad268dc since it broke multi-column __in lookups and _meta.order_wrt on Oracle.
2017-04-27Refs #20939 -- Moved subquery ordering clearing optimization to the __in lookup.Simon Charette
Queries could potentially be resolved in cases where ordering matter.
