【问题描述】：

我在 Django 中遇到错误。我看到了很多类似的问题，但无法找到有效的解决方案。我认为错误在于导入用户模型。我无法找到解决方案。基本上，它似乎无法获取 User 模型。请帮忙。

谢谢。

【问题讨论】：

请张贴您的investor/__init__.py 文件的内容。
@AshishNitinPatil 它只包含from . import urls，在urls.py的主要urls.py中需要作为include()。
但是为什么一定要把它包含在__init__.py 中呢？为什么不在必要时显式导入urls？
@AshishNitinPatil 因为它给出了这个错误，否则File "E:\Python\TheRandomSite\TheRandomSite\urls.py", line 28, in <module> url(r'^investor/', include(investor.urls)), AttributeError: 'module' object has no attribute 'urls'

【解决方案1】：

试试这个

将investor/__init__.py设为空，然后

include('investor.urls')

哦！我不知道你可以使用字符串。谢谢。
