Whatz up?!
The integration of django-register is awesome! But if you want to customize it with additional models it can be confusing.
Here in example I will show how to create your custom backend, form to handle it (custom validator and model choice field).
Note, the django I use is version v1.5.4 django-registration v1.0. Some line breaks are imposed due to layout of this page.
Thus, bellow you will find everything you need to:
Below is and example extending

- Create custom backend
- Add custom form
- Create custom validation
- Badabung! :D
from registration.backends.default.views.RegistrationViewFirst of all, inherit RegistrationView, then override register() and get_form_class() functions. In the examples to follow it is assumed that the class is saved to regbackend.py.
#regbackend.py
from registration.backends.default.views import RegistrationView
#create custom registration backend
class StudentBackend(RegistrationView):
'''
we just want to override register and fix profile creation
'''
def register(self,request, **kwargs):
from usermanager.models import Profile
user=super(StudentBackend,self).register(request, **kwargs)
user.first_name = kwargs['first_name']
user.last_name = kwargs['last_name']
user.save()
profile = Profile.objects.create(
user=user, course=kwargs['course'])
profile.save()
def get_form_class(self, request):
"""
Return the default form class used for user registration.
"""
from usermanager.form import UserRegistrationForm
return UserRegistrationForm
Below is the code from urls.py. Nothing fancy, just import your registration backend, and form, and redirect accounts/register/ to your backend.
#urls.py
from regbackend import StudentBackend
from form import UserRegistrationForm
urlpatterns = patterns('',
url(r'^accounts/register/$',
StudentBackend.as_view(form_class = UserRegistrationForm),
name='registration_register'),
(r'^accounts/', include('registration.backends.default.urls')),
#more url configs
)
Following code is from form.py:

Models used in this example:

class Course(models.Model):
code = models.CharField(max_length=6)
teacher = models.CharField(max_length=30)

def save(self,*args,**kwargs):
self.updated_local = datetime.now()
super(Profile, self).save(*args,**kwargs)

python manage.py syncdb
