AttributeError: 'User' object has no attribute 'check_password' error in Django?

Question

I have a custom model with which I am trying to authenticate:

class User(models.Model):
    #id = models.IntegerField(primary_key=True)
    #identifier = models.CharField(max_length=40, unique=True, db_index=True)
    username = models.CharField(max_length=90, unique=True, db_index=True)
    create_time = models.DateTimeField(null=True, blank=True)
    update_time = models.DateTimeField(null=True, blank=True)
    email = models.CharField(max_length=225)
    password = models.CharField(max_length=120)
    external = models.IntegerField(null=True, blank=True)
    deleted = models.IntegerField(null=True, blank=True)
    purged = models.IntegerField(null=True, blank=True)
    form_values_id = models.IntegerField(null=True, blank=True)
    disk_usage = models.DecimalField(null=True, max_digits=16, decimal_places=0, blank=True)
    #last_login = models.DateTimeField()

    objects = UserManager()
    USERNAME_FIELD = 'username'
    #check_password(password)
    class Meta:
        db_table = u'galaxy_user'

I have mentioned this in `settings.

AUTH_USER_MODEL = 'fileupload.user'

 #views.py
        def login_backend(request):
            if request.method == 'POST':
                username = request.POST['username']
                password = request.POST['password']
                user = authenticate(username=username, password=password)
                if user is not None:
                    login(request, user)
                    return HttpResponseRedirect('/overview/')
                else:
                    return HttpResponseRedirect('/login_backend/')
            else:
                return render_to_response('login_backend.html', context_instance=RequestContext(request))

However I am getting this error:

AttributeError: 'User' object has no attribute 'check_password' error 

What am I doing wrong?

As described in the custom user documentation, your User model must inherit from django.contrib.auth.models.AbstractBaseUser, which adds all the relevant methods.
