How to add extra fields to django registration form?

Question

I have a registration form which generates in view. Now I need to add some fields from other model. How should I change view to add fields from another model?

Here is my view code:

def register(request):
    """ User registration """
    if auth.get_user(request).username:
        return redirect('/')

    context = {}
    context.update(csrf(request))
    context['form'] = UserCreationForm()
    if request.POST:
        newuser_form = UserCreationForm(request.POST)
        if newuser_form.is_valid():
            newuser_form.save()
            newuser = auth.authenticate(username=newuser_form.cleaned_data['username'],
                                    password=newuser_form.cleaned_data['password2'])
        auth.login(request, newuser)
        return redirect('/')
        else:
            context['form'] = newuser_form

    return render(request, 'user_auth/user_auth_register.html', context)

Something like this should help you:

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class UserCreateForm(UserCreationForm):
    extra_field = forms.CharField(required=True)

    class Meta:
        model = User
        fields = ("username", "extra_field", "password1", "password2")

    def save(self, commit=True):
        user = super(UserCreateForm, self).save(commit=False)
        user.extra_field = self.cleaned_data["extra_field"]
        if commit:
            user.save()
        return user

Basically, extending UserCreationForm and adding an extra field. Also, save it in the save() method.

Hope it helps.
