Features deprecated in 1.10
===========================
Direct assignment to a reverse foreign key or many-to-many relation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Instead of assigning related objects using direct assignment::
>>> new_list = [obj1, obj2, obj3]
>>> e.related_set = new_list
Use the :meth:`~django.db.models.fields.related.RelatedManager.set` method
added in Django 1.9::
>>> e.related_set.set([obj1, obj2, obj3])
This prevents confusion about an assignment resulting in an implicit save.
