23582	Django 1.7 initial data can't relies on other apps one.	Nicals	prince889035-sys	"In django 1.7, we are told to create initial data using datamigrations instead of fixtures.

But if those initial data depends on other initial data that are created during a post_migrate signal catch we can't access them. Same thing if I need to relies on other apps initial data create on a datamigration : I never know in which order these data are created.

A typical scenario I'm facing:

I need a group spam_user_group that have some django.contrib.admin autogenerated permission in it. I can't relly on python script in datamigration to fetch the Permission I need because their are created within a post_migrate signal.

If I try to create those migrations in my own post_migrate signal handler, I can't be sure that my script will be executed after django.contrib.admin ones.

Maybe I've misunderstood the documentation about this point, but after a lot of tries and fails I couldn't find a clean way to achieve the scenario I'm presenting here. Maybe this tickets is not a bug, but in this case some documentation about that is to be added."	Cleanup/optimization	assigned	Documentation	1.7	Normal		initial data,migrations		Accepted	1	0	0	0	0	0
