Question

I want that users must fill out a form after the first login. With the signals I’ve already tried:

# -*- coding: utf-8 -*-
from django.contrib.auth.signals import user_logged_in
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse

[...]

def umleiten(sender, user, request, **kwargs):
    print reverse("first_login")
    """Check if a user logged on for the first time.""" 
    return HttpResponseRedirect(reverse("first_login"))

user_logged_in.connect(umleiten)

The function “umleiten” is called but it will not be forwarded to the appropriate page.
Is there a way to call a function after the login from which I can forward to another site.

You can and probably should use middleware for that

class FirstLoginCheckMiddleware(object):
    def process_request(self, request):

        is_form_page = request.path in (
            settings.FORM_PAGE
        )

        if (not is_form_page) and request.user.is_authenticated() and (not request.user.profile.filled_out_the_form):
            return HttpResponseRedirect(settings.FORM_PAGE)
        return None

Where, e.g. you’ve extended User with an object that has a BooleanField which gets checked once the user did what you’ve wanted them todo:

class UserProfile(models.Model):
     filled_out_the_form = field.BooleanField(default=False)
     # ...
