不支持按文件名导入 Django

Question

我是 django 新手，我正在尝试按照Need a minimal Django file upload example 说明创建文件上传页面。但是，我不断收到“不支持导入文件”错误。

这里似乎发生了实际错误：

C:\Users\AppData\Local\Continuum\Anaconda\lib\importlib\__init__.py in import_module
            __import__(name) ...

完整回溯：

Answer 1

这是你的错误发生的地方：

url(r'^$', 'http://127.0.0.1:8000/home/', name='home'),

正如评论者所建议的，这应该是：

from .views import view_name
url(r'^$', view_name, name='home'),
