我在尝试解决User Registration with error: no such table: auth_user后收到错误
通过关注Manager isn't available; User has been swapped for 'pet.Person'
我仍然无法使用我的自定义用户注册表注册用户，而且我已经被困了将近2周。我很抱歉，如果我问一个非常基本的问题，但我只是想不通为什么我仍然无法注册我的用户。我的注册页面不会验证。

在views.py中删除
from django.contrib.auth.forms import UserCreationForm
并在下面使用CustomUserCreationForm代替UserCreationForm。
