Python Django cms URL

我是django cms的新手，我费了一点劲才把它安装到我的电脑上。现在我已经在里面创建了一个页面。现在，当我查看该页面时，url是

http://localhost:8000/first/?preview

我试图使用url访问该页面

http://localhost:8000/first/

但它没有显示任何东西。 我还在覆盖url中更新了url，但未成功：( 有什么东西我遗漏了吗

编辑1-- 这就是错误所在

> Page not found (404)
Request Method:     GET
Request URL:     http://localhost:8000/first/

看起来你的urls.py可能不正确。我看不到你的项目包被导入到哪里。我假设cms是应用程序的名称，而不是这里的项目。看起来你可能根本没有定义urlpatterns变量，但我不确定，因为格式有点奇怪。如果你的项目名为mypr项目URL.py应该如下所示

from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
  url(r'^admin/', include(admin.site.urls)),
  url(r'^', include('myproject.cms.urls')),
)

问题中发布的URL.py是正确的。预览的问题是，它允许登录的管理员查看未发布的页面。要在不预览的情况下查看页面，您必须将其发布。

在django 2.4.2中，对页面进行更改后，只需单击“发布草稿”按钮。这将使页面公开，并可从url

http://localhost:8000/first/

你能发布你的URL.py、views.py，以及调试打开时可能出现的实际错误输出吗？有人能帮我吗？我试过了，我的项目名是myproject。但没有成功。当我把它改成“myproject”时。它现在甚至没有显示django cms主页。您的cms应用程序中是否有另一个映射“first/”的url.py到views.py中定义的实际视图？不，但我认为问题现在解决了。我没有选中页面编辑部分的“发布”复选框。我现在选中了它，它现在工作正常。啊，很酷，很高兴听到。我仍然认为URL.py看起来不太好，但这可能是因为格式导致我错过了一些内容。如果它工作正常，请g、 然后继续。谢谢，伙计，最后一个问题。如何学习django cms。我想建立一个应用程序，它将有一个管理面板，管理员将上传产品到不同的类别。如何继续使用django cms的应用程序？
