[Solved]-Django 1.7 makemigrations freezing/hanging

Django 1.7 had this bug apparently that can cause migrations for a large enough number of models to freak out. They said they were doing something about this, and seems like they might have fixed it in 1.7.1.

https://docs.djangoproject.com/en/1.7/releases/1.7.1/

It’s the third entry, and there’s a few more improvements that may be connected to this.

Heard it first in this talk, hope it solves your problem: https://www.youtube.com/watch?v=bjIXZ-XX2SM

Are there open connections to the database you’re migrating? If so, that is probably the reason your migration hangs. See this south bug for more information. I realise that Django 1.7 does not use south and that bug refers specifically to south. Migrations are built directly in Django 1.7, but since other people have the same problem, I fear this issue is still around.

I had exactly the same issue, and as suggested in another answer i tried to eliminate applications in INSTALLED_APPS and then found my app which was causing this behavior.

Finally this line of code was the cause:

import fabric

when i removed it everything worked fine.

I noticed (following first django tutorial) that adding new field to the model class causes makemigrations to hang. Editing existing field, removing field, adding new model class – it all works, only adding new field to existing class hangs. Im not sure if this is also the case in 1.8 version.

Edit: this only happens in git bash under windows 7. when I try windows cmd console – it works.
