Re: I have several models throwing this error: "AppRegistryNotReady: Models aren't loaded yet."

[Russell Keith-Magee]

Hi Sabine,

Yes, this error is related to 1.7; no, it's not related to migrations. It's related to the App Loading refactor:

https://docs.djangoproject.com/en/1.7/releases/1.7/#app-loading-refactor

The error is caused because you're interacting with Django models before all the models are known to be loaded. If you're starting a completely vanilla Python shell, (i.e., not manage.py shell), then the error has been caused because you haven't called django.setup() - this is a new method required in 1.7 to bootstrap the Django environment.

If you're seeing this error in a manage.py, then there is clearly some sort of complex interaction occurring during the loading of your models; we'll need more details about your setup to be able to diagnose what is going on.

You'll find more details about the new App infrastructure in the docs:

https://docs.djangoproject.com/en/1.7/ref/applications/

Yours,

Russ Magee %-)

Mostly it is models in the same app: one is fine and the other one throws this error, when I call them from my shell: 

I start my shell and run 

x=<MyModel>.objects.all() 

which runs fine, but then when I want to show x by:

print x 

the error occurs. 

I really do not know what it means, googling it did not help at all. Please help. It seems to be something special to Django 1.7? Is it related with migrations?
