Django won't import my model?

Question

Django

models.py

from django.db import models
from news.models import New

......

Terminal:

......
 File "/home/alexander/my_project/poliv/news/models.py", line 3, in <module>
    from tour_category.models import TourCategory
  File "/home/alexander/my_project/poliv/tour_category/models.py", line 2, in <module>
    from news.models import New
ImportError: cannot import name 'New'

Answer 1

Cyclic dependencies, perhaps? In news/models.py do you import models from tour_category/models.py and vice versa?
