Python Django身份验证\u后端导入错误

在settings.py中导入自定义后端的正确方法是什么？我当前在settings.py中有以下内容：

AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth')

"""Django settings for apployment project.

其中，apployment_site是应用程序，auth是文件名，CustomAuth是类名

在我看来，在运行以下代码后，我得到：

ImportError:a看起来不像模块路径

：

from django.contrib.auth import authenticate
from apployment_site import *
authenticate(username="username", password="password")

以下是我的完整设置.py：

AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth')

我认为您实际上不需要将其导入到

视图中。根据，当您调用
authenticate（）
时，Django将检查您的所有身份验证后端

因此，只需确保在
settings.py
中具有所需的所有身份验证后端
 确保它是一个元组：

AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth',)

注意右边末尾的逗号，但是Django似乎不喜欢我在settings.py中引用自定义后端的方式。你知道它的正确语法是什么吗？“apps.apployment\u site.auth.CustomAuth”和“apployment\u site.auth.CustomAuth”都不工作您的目录结构是什么？您的CustomAuth位于哪里？另外，为什么您的视图代码中有来自apployment\u站点导入的
*
？这不是抛出错误的原因吗？不，这只是导入我的模型。当我定义身份验证时，错误在my settings.py中。目前，auth是在my apployment_站点应用程序中定义的文件，主类称为CustomAuth。这就是为什么我假设AUTHENTICATION\u BACKENDS=（'apps.apployment\u site.auth.CustomAuth'）是引用此内容的正确方法。您可以发布整个
settings.py
文件吗？奇怪的是，上面说的“a”看起来不像模块路径。当然，我编辑了我的原始帖子来包含它。谢谢你的帮助！这是正确的，谢谢！我还必须删除“应用程序”。正确的行是AUTHENTICATION\u BACKENDS=（'apployment\u site.auth.CustomAuth'，）我有同样的问题，但AUTHENTICATION\u BACKENDS=（'apployment\u site.auth.CustomAuth'，）对我不起作用。上面写着ImportError：没有名为apployment_site的模块。auth@Nitheesh，您的自定义应用程序的名称实际上是
apployment\u站点
，还是有所不同？您的python模块
custom\u app\u name.auth.py
是否包含
CutomAuth
类？
