15696	Add pre_insert signal to loaddata command	Jonas H.	nobody	"Here's a patch that adds a `pre_insert` signal to the `loaddata` command, allowing to do extra modifications on deserialized objects before saving them to the database.

Here's my use case: SQL databases use integer primary keys, MongoDB uses ObjectIds, and I want to re-use SQL-style fixtures (as found in the Django test suite) to test Django MongoDB Engine (the Django MongoDB backend).  I think this is a painless way to solve this problem: Very little code changes and doesn't require any ugly hacks.

Would be great if this could be applied!"	New feature	closed	Core (Serialization)	dev	Normal	wontfix	nonrel		Design decision needed	1	1	0	1	0	0
