如何解决 python django urls.py 中的递归错误

Question

我对 django 还是很陌生，并且在 https://github.com/mkaykisiz/DjangoS3Browser/ 的一个项目上工作，在添加 "url(r'^' + settings.S3_BROWSER_SETTINGS + '/', include('djangoS3Browser .s3_browser.urls'))," 到 url.py 的行

项目结构： 我有 s3_browser 目录下的视图，因此导入了相同的你能纠正我吗？下面是我的项目结构：

└───djangoS3Browser

    └───manage.py

    ├───s3_browser

    │   └───__pycache__

        └─── operations.py

                                └─── settings.py

                                └─── urls.py

                                └─── views.py

                                └─── wsgi.py

              ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

您正在导入错误的设置和视图文件。只需修改您的代码，如下所示：

from django.conf import settings
from django.conf.urls import url, include
from django.conf.urls.static import static

from your_app import views
import sys

urlpatterns = [
                  url(r'^get_folder_items/(.+)/(.+)/$', views.get_folder_items, name='get_folder_items'),
                  url(r'^upload/$', views.upload, name='upload'),
                  url(r'^create_folder/$', views.create_folder, name='create_folder'),
                  url(r'^download/$', views.download, name='download'),
                  url(r'^rename_file/$', views.rename_file, name='rename_file'),
                  url(r'^paste_file/$', views.paste_file, name='paste_file'),
                  url(r'^move_file/$', views.move_file, name='move_file'),
                  url(r'^delete_file/$', views.delete_file, name='delete_file'),
                  url(r'^' + settings.S3_BROWSER_SETTINGS + '/', include('djangoS3Browser.s3_browser.urls')),
              ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

编辑：您需要通过 pip 安装 djangoS3Browser 并将其添加到您的现有项目中，而不是复制到您的工作区。就像在他们的 github 仓库中一样：

只需将应用程序添加到 Django 项目中，添加一些设置，您就可以浏览云容器和隐含的子目录，以及查看/下载对象。

所以你需要在 django 中使用django-admin startproject mysite 命令创建一个项目，然后将 djangoS3Browser 作为应用程序导入。
