Simon Charette 9f7772e098 Fixed #28884 -- Fixed crash on SQLite when renaming a field in a model referenced by a ManyToManyField.
Introspected database constraints instead of relying on _meta.related_objects
to determine whether or not a table or a column is referenced on rename
operations.

This has the side effect of ignoring both db_constraint=False and virtual
fields such as GenericRelation which aren't backend by database level
constraints and thus shouldn't prevent the rename operations from being
performed in a transaction.

Regression in 095c1aaa89.

Simon Charette 08654a99bb Fixed #28492 -- Defined default output_field of expressions at the class level.
This wasn't possible when settings were accessed during Field initialization
time as our test suite setup script was triggering imports of expressions
before settings were configured.
2017-09-11 12:22:39 -04:00
Simon Charette 13be453080 Refs #28492 -- Stopped accessing settings at Field.db_tablespace initialization.
Deferring accesses to settings allows database fields to be initialized before
settings are loaded.

Mariusz Felisiak 179b247e07 Removed useless condition from Oracle's NullBooleanField's check constraint.
NULL cannot be compare with standard operators on Oracle, it works only
with IS NULL and IS NOT NULL operators. Therefore 'OR ... IS NULL'
condition in NullBooleanField's check constraint is redundant.
Nullability is checked in a separate constraint.
2017-09-05 11:17:06 +02:00

superclass' deferred field.

Thanks Simon Charette for the suggested fix.
2017-08-31 09:35:05 -04:00
Tim Graham e5bd585c6e Fixed #28543 -- Prevented ManyToManyField.value_from_object() from being lazy.
Previously, it was a QuerySet which could reevaluate to a new value if the
model's data changes. This is inconsistent with other Field.value_from_object()
methods.

This allows reverting the fix in the admin for refs #27998.
