Django create custom UserCreationForm

Question

I enabled the user auth module in Django, however when I use UserCreationForm it only asks for username and the two password/password confirmation fields. I also want email and fullname fields, all set as required fields.

I've done this:

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

class RegisterForm(UserCreationForm):
    email = forms.EmailField(label = "Email")
    fullname = forms.CharField(label = "Full name")

    class Meta:
        model = User
        fields = ("username", "fullname", "email", )

Now the form shows the new fields but it doesn't save them to the database.

How can I fix this?

Answer 1

There is no such field called fullname in the User model.

If you wish to store the name using the original model then you have to store it separately as a first name and last name.

Edit: If you want just one field in the form and still use the original User model use the following:

You can do something like this:

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

class RegisterForm(UserCreationForm):
    email = forms.EmailField(label = "Email")
    fullname = forms.CharField(label = "First name")

    class Meta:
        model = User
        fields = ("username", "fullname", "email", )

Now you have to do what manji has said and override the save method, however since the User model does not have a fullname field it should look like this:

def save(self, commit=True):
        user = super(RegisterForm, self).save(commit=False)
        first_name, last_name = self.cleaned_data["fullname"].split()
        user.first_name = first_name
        user.last_name = last_name
        user.email = self.cleaned_data["email"]
        if commit:
            user.save()
        return user

Note: You should add a clean method for the fullname field that will ensure that the fullname entered contains only two parts, the first name and last name, and that it has otherwise valid characters.
