title: Django registration Type error at /accounts/register/ get_success_url() missing 1 required positional argument: 'user'
body: <p>Using the Django registration redux plugin to create a form page after a user has successfully registered for my app. However I keep receiving this error <code>TypeError at /accounts/register/
  get_success_url() missing 1 required positional argument: 'user'</code> after completing the registration. It should redirect to a page with a form shown in the method below</p>
  
  <pre><code>from registration.backends.simple.views import RegistrationView
  
  
  # my new reg view, subclassing RegistrationView from our plugin
  class MyRegistrationView(RegistrationView):
      def get_success_url(self, request, user):
          # the named URL that we want to redirect to after
          # successful registration
          return ('registration_create_word')
  </code></pre>
  
  <p>Here is the url path
  <code>path('accounts/create_word/', views.create_word, name='registration_create_word'),</code></p>
  
  <p>I have attempted changing the parameters to just <code>user</code> however i received the same error except it is missing <code>self</code>. 
  Not sure what I am missing. I found a similar question (<a href="https://stackoverflow.com/questions/17708787/how-to-redirect-users-to-a-specific-url-after-registration-in-django-registratio?noredirect=1&amp;lq=1">How to redirect users to a specific url after registration in django registration?</a>) however i still am receiving errors</p>
  
  <p>any help would be greatly appreciated. </p>
