30849	Enabling hooking into the autodetector from a third-party app.	Emil 'Skeen' Madsen	Emil 'Skeen' Madsen	"Idea and motivation presented on the [https://groups.google.com/forum/#!searchin/django-developers/sovende@gmail.com|sort:date/django-developers/kqWJ2WsMW6w/TRakYLNRBQAJ mailinglist]

Summed up, what I suggest is:
- Creating a new signal fired from within the autodetector to allow third-party apps to generate migrationfiles with their own custom operations within them.

One compelling use-case for this, is automatically generating database constraints based upon querysets (see the mailinglist post for details)."	New feature	assigned	Migrations	2.2	Normal		automigrator		Unreviewed	0	0	0	0	0	0
