Question

我试图在我的views.py中使用CreateView泛型类，并且它所引用的模型具有用户属性（来自django的内置User类）作为外键。

models.py

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.urls import reverse

class UserProfile(models.Model):
    user = models.ForeignKey(User,on_delete=models.CASCADE)
    description = models.CharField(max_length=100, default='')
    city = models.CharField(max_length=100,default='')
    website = models.URLField(default='')
    phone = models.IntegerField(default=0)

    def get_absolute_url(self):
        return reverse('profile', kwargs={'pk': self.pk})

views.py

from accounts.models import UserProfile
from django.views.generic.edit import CreateView

class RegisterUserView(CreateView):
    model =  UserProfile
    fields=['username','first_name','last_name','email','password1','password2']

urls.py

path('register/',RegisterUserView.as_view() , name='register')

给出了错误：

FieldError at /accounts/register/

Unknown field(s) (last_name, password1, username, email, password2, first_name) specified for UserProfile

我的问题是：CreateView可以从用户属性获取数据并创建一个Modelform，还是我必须创建一个自定义ModelForm？

Answer 1

您必须创建User的实例，然后将此实例附加到UserProfile user字段。

由于未为UserProfile定义这些字段（last_name，password1，用户名，电子邮件，password2，first_name）而导致错误

而且BTW django的User类没有password1和password2属性

Django：在具有Foreignkey属性的模型中使用CreateView
