Import error in django

Question

I have two files within the same folder (app) feed.

models.py

from django.db import models
from .managers import FeedManager

class Feed(models.Model):
    #fields for my model

managers.py

from django.db import models

from .models import Feed

class FeedManager(models.Manager):
    def get_queryset(self, *args, **kwargs):
        return super(FeedManager, self).get_queryset(*args, **kwargs)

I get the following error when I run the server:

      Unhandled exception in thread started by <function wrapper at 0x04064370>

    from .managers import FeedManager
  File "C:\Users\Sumit\Desktop\django\network\feed\managers.py", line 3, in <module>
    from .models import Feed
ImportError: cannot import name Feed

Why am I getting this error and how do I fix this ?

You're facing circular import issue. Remove the `.models import Feed` from the top of your `managers.py` file, and you'll be good to go. Whenever you need the model, you can import it inside the manager function itself. — Rohit Jain, May 29 '16 at 08:37

You've introduce introduced a circular import: models module depends on managers module which in turn depends on the models module.

Neither of the modules can be resolved since their dependency cannot be resolved. Try re-organizing your modules.
