python - Django无法通过管理员下载文件

我正在使用Django 1.10.5版建立安装了以下应用程序的网站：


django.contrib.admin
django.contrib.auth
django.contrib.contenttypes
django.contrib.sessions
django.contrib.messages
django.contrib.staticfiles
bootstrap3
myapp
储物


在models.py中，我定义了以下类：

class SourceData(models.Model):
    File = models.FileField(blank=True, null=True, upload_to='Upload')

在网站上，我尝试通过admin上传文件，成功。但是，如果我单击上载的文件，则会出现页面未找到404错误。

任何帮助或想法赞赏。
提前致谢！

最佳答案

可能您需要将此行添加到urls.py文件中（导入所需的库）

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_URL)
