如何使用UserProfile中的字段扩展UserCreationForm [英] How to extend UserCreationForm with fields from UserProfile

问题描述

我发现这个 post 关于如何使用额外的字段（如电子邮件）扩展UserCreationForm。但是，电子邮件字段已经在预先建立的用户模型中定义了。

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.

我创建了一个额外的模型（称为UserProfile），它可以延续Django的预先构建的User类。如何使用UserProfile中定义的这些字段出现在我的UserCreationForm中？

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?

推荐答案

根据您的 UserProfile 模型（不幸的是，使用 ModelForm 避免重复自己并不容易），然后创建并保存新的code> UserProfile 实例在覆盖的 save（）函数中。改编自您链接到的帖子：

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
