Question

我希望能在这个问题上寻求一些帮助。我还在学习Django（和Python）并遇到这个我无法找到答案的特殊问题。我创建了一个名为“新闻”的新应用程序，并为应用程序设置了模型。使用Admin界面我创建了一些数据。在我的“Pages”应用程序中，我正在尝试导入News_Article类并获取错误No module News.models。

我很难看到这里出了什么问题。

非常感谢任何协助。

Answer 1

切换

from News.models import News_Article

到

from Bolton_GC.News.models import News_Article

Answer 2

只是详细说明@TheLifeOfSteve的答案，所有import语句都始终与manage.py文件相关。

如果manage.py文件位于Bolton_GC / Bolton_GC路径，那么正确的import语句就是：

from News.models import News_Article

但是在当前的目录结构中，以下是史蒂夫指出的正确答案。

from Bolton_GC.News.models import News_Article

Answer 3

也有同样的问题，但对我而言，这是一次名称冲突。我已将我的应用命名为路径中的另一个模块。我重构了应用名称，就解决了问题。

Answer 4

导入和注册模型有更新！！请尝试从 .models 导入 News_Article

Answer 5

试试从 .models 导入 News_Article

Django：无法从另一个App导入模型
