That's correct. That's your job and the documentation gives you a hint on how 
to do it:

These profile models are not special in any way - they are just Django models 
that happen 
to have a one-to-one link with a user model. As such, they aren’t auto created 
when a user 
is created, but a django.db.models.signals.post_save[1] could be used to create 
or update 
related models as appropriate.

It took me awhile to figure out that dcf_profile is the text you use as 
related_name for the User model.

It looks like this is where you are having trouble. The code is trying to 
call the dcf_profile attribute/method from the user object - which doesn't 
exist. 

Your end goal appears to be to call the all_add_item() function. Why not 
grab an instance of your CustomUser first and invoke it on that? Something 
like,

def dispatch(self, *args, **kwargs):
user = self.request.user
my_user = CustomUser.objects.get(auth_user_ptr=user)  # Assuming you 
have entry in your database
if not my_user.allow_add_item():
