How to extend UserCreationForm with fields from UserProfile

问题

I found this post on how to extend the UserCreationForm with extra fields such as "email." However, the email field is already defined in the pre-built user model.

I created an extra model (called UserProfile) that futher extends Django's pre-built User class. How do I get these fields I defined in UserProfile to appear in my UserCreationForm?

回答1:

Add fields as appropriate for your UserProfile model (it's not too easy to use a ModelForm to avoid Repeating Yourself, unfortunately), then create and save a new UserProfile instance in the over-ridden save() function. Adapted from the post you linked to:

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


class UserCreateForm(UserCreationForm):
    job_title = forms.CharField(max_length=100, required=True)
    age = forms.IntegerField(required=True)

    class Meta:
        model = User

    def save(self, commit=True):
        if not commit:
            raise NotImplementedError("Can't create User and UserProfile without database save")
        user = super(UserCreateForm, self).save(commit=True)
        user_profile = UserProfile(user=user, job_title=self.cleaned_data['job_title'], 
            age=self.cleaned_data['age'])
        user_profile.save()
        return user, user_profile
