Accessing a django model in middleware (django>1.7) -

i'm upgrading django 1.6.5 django 1.9, , in process upgrading several middleware classes. of middleware classes use models during process_request or process_response phases. however, i'm getting appregistrynotready: apps aren't loaded yet. error attempting use them.

is there way import models during middleware?
should move import statements process_request / process_response methods?

you need use new api wsgi handler:

from django.core.wsgi import get_wsgi_application  application = get_wsgi_application() 

this call django.setup() you, populate app registry.
