Django 2.0，URL 路由导致最大递归 check_method

Question

我是 Django 的新手，我在将 Django "app" 添加到创建的 Django "project" 时遇到了问题。我正在使用 Docker 和 Docker-Compose，当我尝试使用添加的 "documents" 应用构建和启动我的实例时，它会抛出最大递归错误。

如果我从项目中删除文档应用程序，则不会出现此问题，因此显然我的应用程序配置有误。

有人看到我在将默认 URL ('') 设置为文档中的索引视图时做错了什么吗？

如果您使用 Django 2.0，您应该阅读此文档：https://docs.djangoproject.com/en/2.0/ref/urls/，此版本中的 url 配置已更改。但是，如果你真的想在 Django 2.0 中使用正则表达式，你可以更改：

from django.conf.urls import url

至；

from django.urls import re_path

你的例子；

from django.conf.urls import url

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', Index.as_view())
    # url(r'$^', documents.views.index, name='index')
]

至；

from django.urls import re_path

urlpatterns = [
    re_path(r'^admin/', admin.site.urls),
    re_path(r'^$', Index.as_view()),
]
