Django import error: No module named models

Question

I keep receiving the error Could not import movies.views. Error was: No module named models

Here is my traceback:

    Exception Value: Could not import movies.views. Error was: No module named models

I am not sure why I have this error. My code is as follows...

I have an django app called tracking and another called movies. I have a python file called tracking.py in the tracking app it consists of the following code:

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()

The above is pretty basic stuff. My views.py in my movies app uses the tracking.py file here:

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

UPDATE:

Here are the contents of 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)

The error appears to come from the import line from tracking.models import MovieView in the tracking.py file and I am not sure why. As soon as I comment out that line the error goes away but then of course I'll have new errors about MovieView not existing as expected. I don't see anything wrong with that import line in tracking.py.

Does anyone have any suggestions as to why I receive that error and how I can resolve this?

Answer 1

Can you try

from models import MovieView

instead of

from tracking.models import MovieView

The reason being both models.py and tracking.py are in the same app folder "tracking", you don't need to write tracking.models, this will make Django think that you have a folder named models inside the tracking directory.
