Mariusz Felisiak 3a941230c8
Fixed #31584 -- Fixed crash when chaining values()/values_list() after Exists() annotation and aggregation on Oracle.
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the GROUP BY clause.

Regression in efa1908f66.
2020-05-14 15:07:08 +02:00
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.

Simon Charette 42c08ee465 Fixed #31566 -- Fixed aliases crash when chaining values()/values_list() after annotate() with aggregations and subqueries.

Simon Charette 1d16c5d562 Refs #27666 -- Ensured relationship consistency on delayed reloads.
Delayed reloads of state models broke identity based relationships
between direct and non-direct ancestors.

Basing models.Options related objects map of model labels instead of
their identity ensured relationship consistency is maintained.

reference validation.
2020-04-06 10:19:49 +02:00
Simon Charette 98ea4f0f46 Refs #7098 -- Deprecated passing raw column aliases to order_by().
Now that order_by() has expression support passing RawSQL() can achieve
the same result.

This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.

Simon Charette 9f07f27124 Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL.
Both backends order NULLs first on ascending ordering and last on
descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when
asc(nulls_first) and desc(nulls_last) are used since it prevents indice
usage.

Mariusz Felisiak bf77669453
Fixed #29998 -- Allowed multiple OneToOneFields to the parent model.
We assumed that any OneToOneField's in a child model must be the
parent link and raised an error when parent_link=True was not
specified. This patch allows to specify multiple OneToOneField's to
the parent model.

OneToOneField's without a custom related_name will raise fields.E304
and fields.E305 so this should warn users when they try to override
the auto-created OneToOneField.

Baptiste Mispelon 09341856ed Used Signature API instead of deprecated inspect.getcallargs().

it follows the __wrapped__ attribute set by functools.wraps for
example).

Simon Charette 379bf1a2d4 Fixed #8467 -- Prevented crash when adding existent m2m relation with an invalid type.
This was an issue anymore on backends that allows conflicts to be
ignored (Refs #19544) as long the provided values were coercible to the
expected type. However on the remaining backends that don't support
this feature, namely Oracle, this could still result in an
IntegrityError.

By attempting to coerce the provided values to the expected types in
Python beforehand we allow the existing value set intersection in
ManyRelatedManager._get_missing_target_ids to prevent the problematic
insertion attempts.

Thanks Baptiste Mispelon for triaging this old ticket against the
current state of the master branch.

The previous solution was only handling lookups against related fields
pointing at AutoFields and would break for foreign keys to other fields.

It was also causing bidirectional coupling between model fields and
expressions which the method level import of OuterRef was a symptom of.

Simon Charette 4d1420947e Fixed #30494 -- Disabled __year lookup optimization for indirect values.
The previous heuristics were naively enabling the BETWEEN optimization on
successful cast of the first rhs SQL params to an integer while it was
not appropriate for a lot of database resolved expressions.

Thanks Alexey Chernov for the report.

Rob 6b736dd074 Fixed #30349 -- Fixed QuerySet.exclude() on FilteredRelation.
Using annotated FilteredRelations raised a FieldError when coupled with
exclude(). This is due to not passing filtered relation fields to the
subquery created in split_exclude(). We fixed this issue by passing the
filtered relation data to the newly created subquery.

Secondly, in the case where an INNER JOIN is used in the excluded
subquery, the ORM would trim the filtered relation INNER JOIN in attempt
to simplify the query. This will also remove the ON clause filters
generated by the FilteredRelation. We added logic to not trim the INNER
JOIN if it is from FilteredRelation.

Fixed #30191 -- Selected only referenced fields during cascade deletion.

receivers are connected for their respective model as connected as these
receivers might expect all fields of the deleted model to be present.

Simon Charette 26c4be2ebe Refs #18676 -- Enabled fast-delete for m2m_changed senders.
There's no reason to disable fast-delete when an intermediary
many-to-many model has connected m2m_changed receivers because the
signal is only sent when related manager's clear() and remove() methods
are directly called.

This must have been overlooked in 1cd6e04cd4
given no regression tests fail when m2m_changed is not taken into
consideration to determine if fast-delete can be enabled.

Simon Charette 3543129822 Refs #27149 -- Moved subquery expression resolving to Query.
This makes Subquery a thin wrapper over Query and makes sure it respects
the Expression source expression API by accepting the same number of

It also makes OuterRef usable in Query without Subquery wrapping. This
should allow Query's internals to more easily perform subquery push downs
during split_exclude(). Refs #21703.
