加载 Django 服务器时出现省略号问题

Question

大家好我的问题是： 当我尝试进入我的管理面板时，出现此错误，

ps：我做了一个服装用户的注册系统

   File "C:\Users\Madara\Miniconda3\envs\myEv\lib\site-packages\django\utils\module_loading.py", line 13, in import_string
    module_path, class_name = dotted_path.rsplit('.', 1)
AttributeError: 'ellipsis' object has no attribute 'rsplit'`

` 这是什么意思？

Answer 1

看起来您的

AUTHENTICATION_BACKENDS

设置 [Django-doc] 包含省略号 (

...

)。确实：

AUTHENTICATION_BACKENDS = (

    # Needed to login by username in Django admin, regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',

    # `allauth` specific authentication methods, such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend',
    ...  # <- an ellipsis
)

您应该删除它，以便

AUTHENTICATION_BACKENDS

是：

AUTHENTICATION_BACKENDS = (

    # Needed to login by username in Django admin, regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',

    # `allauth` specific authentication methods, such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend'
)

可能您使用的教程中作者想说您可以添加额外的后端，因此为 reader 指定了省略号以添加更多后端，但 Python 解释器当然会将其读取为

Elipsis

对象，并且 Django 系统不明白你想表达什么。
