Django - Ajax registration

I am trying to allow registration (using this django-registration register view) to one of my applications from a modal dialog.

Since this form is in a modal box, I'd like to get an json reponse on success (instead of the default redirection)

How can I use this view (django-registration register) to manage the registration and send back a json response on success ?

I know how to make ajax/json responses, the question is how to use the django-registration view without the redirection behavior or wrap it into an other view to manage the response.

Solution

First you need to change the urls.py to wrap the existing view with another functionality. To do that you have to create a new backend package in backends folder and change urls.py there while keeping everything else intact, or you could just go ahead and modify the existing urls.py in the backend package.

I have not tested this, but it should work.

Point url to the new view:

# urls.py
url(r'^register/$', register_wrap,
    {'backend': 'registration.backends.default.DefaultBackend'},
    name='registration_register'),

# your new view that wraps the existing one
def register_wrap(request, *args, **kwargs):

    # call the standard view here
    response = register(request, *args, **kwargs)

    # check if response is a redirect
    if response.status_code == 302:
        # this was redirection, send json response instead
    else:
        # just return as it is
        return response

If you are going to need this for more views you can just create a decorator using this.
