Models

In this application, we need to store the data related to each movie and the movies' ratings from each user of the website. We set up three models:

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True)
    array = jsonfield.JSONField()
    arrayratedmoviesindxs = jsonfield.JSONField()
    lastrecs = jsonfield.JSONField()

    def __unicode__(self):
            return self.user.username

    def save(self, *args, **kwargs):
        create = kwargs.pop('create', None)
        recsvec = kwargs.pop('recsvec', None)
        print 'create:',create
        if create==True:
            super(UserProfile, self).save(*args, **kwargs)
        elif recsvec!=None:
             self.lastrecs = json.dumps(recsvec.tolist())
             super(UserProfile, self).save(*args, **kwargs)
        else:
            nmovies = MovieData.objects.count()
            array = np.zeros(nmovies)
            ratedmovies = self.ratedmovies.all()
            self.arrayratedmoviesindxs = json...
