Login after creating a user with formwizard-django

Question

I would like to login after the creation of users. But i'm using formwizard and I've got an error "global name 'request' is not defined" when i try.

Here is my view.py

class ProfilWizard(SessionWizardView):
template_name = "gestionProfil/profil-step1.html"
def done(self, form_list, **kwargs):
    form_data = process_form_data(form_list)
        return render_to_response('gestionProfil/profil.html', {'form_data': form_data})

def process_form_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    username = form_data[0]['username']
    password = form_data[0]['password']
    email = form_data[0]['email']
    user = User.objects.create_user(username, email, password)
    user.first_name = form_data[1]['firstName']
    user.last_name = form_data[1]['lastName']
    user.save()

user = authenticate(username = username, password = password)
if user:
    login(request, user)
return form_data

So how should i do to login after the creation of users?

Edit : After making the edit suggested by user777466 my views.py is now:

class ProfilWizard(SessionWizardView):
template_name = "gestionProfil/profil-step1.html"
def done(self, form_list, **kwargs):
    (form_data,user) = process_form_data(form_list)
    user.backend = 'django.contrib.auth.backends.ModelBackend'
    if user:
        login(self.request, user)
        #return HttpResponse(form_data[0]['password'])
        return render_to_response('gestionProfil/profil.html', {'form_data': form_data})

def process_form_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    username = form_data[0]['username']
    password = form_data[0]['password']
    email = form_data[0]['email']
    user = User.objects.create_user(username, email, password)
    user.first_name = form_data[1]['firstName']
    user.last_name = form_data[1]['lastName']
    user.save()

    return (form_data,user)

The output during and after the form are :

[13/Nov/2013 08:39:12] "GET /gestionProfil/createNew/ HTTP/1.1" 200 4639

[13/Nov/2013 08:39:22] "POST /gestionProfil/createNew/ HTTP/1.1" 200 5085

Edit 2: I've remove my database and made a new syncdb, now the authentication is working.

Answer 1

Your request is not passed through the process_form_data method.

Solution 1 - log the user in the process_form_data method:

form_data = process_form_data(self.request, form_list)
def process_form_data(request, form_list)
  ...

Solution 2 - log the user in the done method:

class ProfilWizard(SessionWizardView):
  template_name = "gestionProfil/profil-step1.html"
  def done(self, form_list, **kwargs):
      form_data = process_form_data(form_list)
      user = authenticate(username = form_data[0]['username'], password = form_data[0]['password'])
      if user:
         login(self.request, user)
        return render_to_response('gestionProfil/profil.html', {'form_data': form_data})

  def process_form_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    username = form_data[0]['username']
    password = form_data[0]['password']
    email = form_data[0]['email']
    user = User.objects.create_user(username, email, password)
    user.first_name = form_data[1]['firstName']
    user.last_name = form_data[1]['lastName']
    user.save()
    return form_data

Recently, I had the authenticate() not working on a project because of the password field. In that case, make a simple :

user.backend = 'django.contrib.auth.backends.ModelBackend'
login(request, user)

So you should have something like:

class ProfilWizard(SessionWizardView):
  template_name = "gestionProfil/profil-step1.html"
  def done(self, form_list, **kwargs):
      form_data = process_form_data(self.request, form_list)         
      return render_to_response('gestionProfil/profil.html', {'form_data': form_data})

  def process_form_data(self, request, form_list):
    form_data = [form.cleaned_data for form in form_list]
    username = form_data[0]['username']
    password = form_data[0]['password']
    email = form_data[0]['email']
    user = User.objects.create_user(username, email, password)
    user.first_name = form_data[1]['firstName']
    user.last_name = form_data[1]['lastName']
    user.save()
    user.backend = 'django.contrib.auth.backends.ModelBackend'
    login(request, user)
    return form_data
