Je ne sais pas pourquoi j'ai cette erreur. Mon code est comme suit...

J'ai un django app appelé tracking et un autre appelé movies. J'ai un fichier python appelé tracking.py dans le tracking application, elle se compose d'utiliser le code suivant:

filmlibrary/tracking/tracking.py

from movies.models import Movie
from tracking.models import MovieView
import os
import base64
def tracking_id(request):
try:
return request.session['tracking_id']
except KeyError:
request.session['tracking_id'] = base64.b64encode(os.urandom(36))
return request.session['tracking_id']
def log_movie_view(request, movie):
t_id = tracking_id(request)
try:
v = MovieView.objects.get(tracking_id=t_id, movie=movie)
v.save()
except MovieView.DoesNotExist:
v = MovieView()
v.movie = movie
v.ip_address = request.META.get('REMOTE_ADDR')
v.tracking_id = t_id
v.user = None
if request.user.is_authenticated():
v.user = request.user
v.save()

Ci-dessus est plutôt un truc de base. Mon views.py dans mon movies application utilise l'tracking.py fichier ici:

filmlibrary/movies/views.py

@login_required
def movie_details(request, slug, template_name="movies/movie_detail.html"):
movie = get_object_or_404(Movie, slug=slug)
movie.tracking_id = tracking.tracking_id(request)
movie.save()
tracking.log_movie_view(request, movie)
context = RequestContext(request, {'movie': movie })
if movie:
try:
screener = movie.moviemedia_set.get(movie_type='screener')
.... continued

Mise à JOUR:

Voici le contenu de filmlibrary/tracking/models.py

from django.db import models
from django.contrib.auth.models import User
from movies.models import Movie
class PageView(models.Model):
class Meta:
abstract = True
date = models.DateTimeField(auto_now=True)
ip_address = models.IPAddressField()
user = models.ForeignKey(User, null=True)
tracking_id = models.CharField(max_length=50, default='')
class MovieView(PageView):
movie = models.ForeignKey(Movie)

L'erreur semble venir de la ligne d'importation from tracking.models import MovieView dans le tracking.py fichier et je ne suis pas sûr pourquoi. Dès que j'en commentaire que la ligne de l'erreur disparaît, mais alors bien sûr, je vais avoir de nouvelles erreurs à propos de MovieView n'existant pas comme prévu. Je ne vois rien de mal à cela la ligne d'importation dans tracking.py.

Quelqu'un aurait-il des suggestions quant à pourquoi je reçois cette erreur et comment je peux résoudre ce problème?
