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.

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.

Sergey Fedoseev 379caf397e Replaced deque() with list() in prefetch_related_objects().

Jeremy Kerr 84b7cb7df0 Fixed #28549 -- Fixed QuerySet.defer() with super and subclass fields.
Previously, deferring fields in different classes didn't omit the
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.
