Best way to do register a user in Django

Question

I'm trying to implement User Registration for my Django app. The book I read mentions UserCreationForm but I need more than just name, password, and email address. I could implement my own user object and use ModelForm I think, but then I lose out on some of the django conveniences for authentication. Finally, I read something about UserProfiles which supplement Users I guess, so I think I need some combination of all of these things. Here's what I have so far.

View - this is simple enough. All I want to do here is create my form and save the user

def main(request):
    rform1 = forms.RegisterForm1()
    rform2 = forms.RegisterForm2()
    return render_to_response("authentication/index.html", {'form1': rform1, 'form2':rform2})

def register(request):
    if request.method == 'POST':
        rform1 = forms.RegisterForm1(request.POST)
        rform2 = forms.RegisterForm2(request.POST)
        if rform1.is_valid() and rform2.is_valid():
            new_user = rform1.save()
            return HttpResponseRedirect("/register-success/")
    return render_to_response("authentication/index.html", {'form1': rform1,'form2':rform2})

Form - this is my form for creating a user. Or the start of it at least

class RegisterForm1(forms.ModelForm):
    class Meta:
        model = User

class RegisterForm2(forms.ModelForm):
    class Meta:
        model = UserProfile

Model - this is my UserProfile that I want to supplement User with.

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    phonenumber = PhoneNumberField()

Is it clear what I'm trying to do? Am I on the right track

Answer 1

Make two model forms, one for the User model and one for the UserProfile model.

class UserForm(django.forms.ModelForm):
    class Meta:
        model = User  

class UserProfileForm(django.forms.ModelForm):
    class Meta:
        model = UserProfile
        exclude = ['user']

Give them prefixes and display them together in the same HTML form element. In the view, check that both are valid before you save the User and then the UserProfile.

def register(request):
    if request.method == 'POST':
        uf = UserForm(request.POST, prefix='user')
        upf = UserProfileForm(request.POST, prefix='userprofile')
        if uf.is_valid() and upf.is_valid():
            user = uf.save()
            userprofile = upf.save(commit=False)
            userprofile.user = user
            userprofile.save()
            return django.http.HttpResponseRedirect(…something…)
    else:
        uf = UserForm(prefix='user')
        upf = UserProfileForm(prefix='userprofile')
    return django.shortcuts.render_to_response('register.html', 
                                               dict(userform=uf,
                                                    userprofileform=upf),
                                               context_instance=django.template.RequestContext(request))

In register.html:

<form method="POST" action="">
    {% csrf_token %}
    {{userform}}
    {{userprofileform}}
    <input type="submit">
</form>

Your best bet is to use James Bennett's django-registration and django-profiles apps - they take care of a lot of this sort of thing for you.
