如何解决提出的错误：没有名为'django.contrib.customuser'的模块 [英] How to solve error raised : No module named 'django.contrib.customuser'

问题描述

我是Django的新手，试图为我的项目创建一个自定义用户。当我运行服务器时，它引发了没有名为'django.contrib.customuser'的模块，有时候管理器不可用; auth.User已被替换为Mysite.CustomUser。即使我更改了我的设置：django.contrib.auth到django.contrib.custommuser。请有人帮我解决这个问题。这是我的代码

I am new to Django, trying to create a custom user for my project. When I am running the server, it raises No module named 'django.contrib.customuser' and sometimes, Manager isn't available; auth.User has been swapped for Mysite.CustomUser. Even i changed my settings: django.contrib.auth to django.contrib.custommuser. Please someone help me solving this. Here's my code

from datetime import datetime
from django.db import models
from django.contrib.auth.models import User, BaseUserManager, AbstractUser,   AbstractBaseUser

from django.utils.translation import ugettext_lazy as _

             is_staff=is_staff, is_active=False, last_login=now, date_joined=now, **extra_fields)

推荐答案

删除 django.contrib.customuser 和 django.contrib .auth 从您的 INSTALLED_APPS 。 customuser 应用程序在 django.contrib 包中，而 auth 可以省略（以避免潜在的名称排除）。

Remove django.contrib.customuser and django.contrib.auth from your INSTALLED_APPS. There is no customuser application under django.contrib package, and auth can be omitted (to avoid potential name colission).

此外，我建议您重新阅读 Django文档验证定制。大多数更改是可选的，并且您的代码应通过重新使用基类来简化，除非您的方法有所不同。
该文档还提到，为了交换用户模型，您需要将设置更新为 AUTH_USER_MODEL ='customuser.CustomUser'。

Furthermore, I suggest you re-read the Django docs on auth customization. Most of the changes are optional, and your code should be simplified by re-using the base classes, unless your methods vary of course. The docs also mentions that for swapping User models, you are required to update settings to AUTH_USER_MODEL = 'customuser.CustomUser'.
