我正在使用自定义用户模型,使用AbstractUser进行扩展.这是我的models.py:

    # -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.contrib.auth.forms import UserCreationForm

from django import forms

# Create your models here.
class User(AbstractUser):
    pass

class SignUpForm(UserCreationForm):
    first_name = forms.CharField(max_length=30, required=False, help_text='Optional.')
    last_name = forms.CharField(max_length=30, required=False, help_text='Optional.')
    email = forms.EmailField(max_length=254, help_text='Required. Inform a valid email address.')

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2', )
enter code here

因此,当我尝试运行开发服务器或迁移数据库时,它会返回以下错误:

Traceback (most recent call last):
  File "./manage.py", …
