python - django删除用户表

Question

我是 Django 新手，正在创建我的第一个应用程序。我创建了一个用户模型，但不明白有一个内置的。我已经删除了用户表。

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

from django.db import models from django.contrib.auth.models import User


# Create your models here.


# class User(models.Model):
#     firstname = models.CharField(max_length=250)
#     lastname = models.CharField(max_length=250)
#     email = models.CharField(max_length=250)
#     password = models.CharField(max_length=250)
#     newsletter = models.BooleanField(default=0)
#     accountlevel = models.BigIntegerField(default=1)
#     reportsCreated = models.BigIntegerField(default=0)
#
#     def __str__(self):
#         return self.firstname +" "+ self.lastname +" - "+self.email



class Account(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    reports = models.IntegerField(default=3)
    accounttype = models.CharField(default='Free')
    monthlycost = models.FloatField(default=0.0)

    def __str__(self):
        return self.user.username + " - " + self.accounttype

admin.py # -- 编码:utf-8 -- 从 future 导入unicode_literals 从 .models 导入用户 从.models导入报告

from django.contrib import admin

# Register your models here.

admin.site.register(User)
admin.site.register(Report)

我现在需要将帐户和报告表中的外键添加到内置用户模型中。

当我运行时:

python manage.py makemigrations

我收到以下错误

django.contrib.admin.sites.AlreadyRegistered: The model User is already registered

Answer 1

从应用的 admin.py 中取消注册模型。

删除下面的行

admin.site.register(User) 

然后makemigrations和migrate。
