Fixed #20094 - Be more careful when checking for Iterator Python 2.6 has some different behaviour when checking isinstance(foo, collections.Iterator). 2013-03-20 18:47:56 +08:00			`from django.db import models`

Fixed #21127 -- Started deprecation toward requiring on_delete for ForeignKey/OneToOneField 2015-07-22 22:43:21 +08:00			`category = models.ForeignKey(Category, models.CASCADE)`
[1.9.x] Fixed #25389 -- Fixed pickling a SimpleLazyObject wrapping a model. Pickling a `SimpleLazyObject` wrapping a model did not work correctly; in particular it did not add the `_django_version` attribute added in 42736ac8. Now it will handle this and other custom `__reduce__` methods correctly. Backport of 35355a4ffedb2aeed52d5fe3034380ffc6a438db from master 2015-09-12 14:06:25 +08:00
