来自不同子页面上的管理面板的帖子
Posts from admin panel on different subpages
我想将 post 列表从主页添加到另一个子页面。 （主页到名为 "programowanie" 的子页面）
例如：
我有一个网站 wwww.example.com。在这个网站上，我有一个从管理面板生成的 post 列表（我可以使用管理面板添加、删除 posts）。
问题是，当我尝试将带有 post 列表的起始页面的模板复制到其他子页面（称为：www.example.com/programowanie）时，它不起作用（我从主页面看到一个模板页面但没有 post 列表）
我认为问题出在 templates/blog/post/list.html in loop {% for post in posts %}
如果我解决了这个问题，我想在管理面板中添加不同的重叠以仅在 "programowanie" 子页面中发布 posts。
这是我的文件：

感谢您的帮助！！ （我在想这第三天）
你的问题出在视图上。
Django 模板必须由视图呈现，您可以从视图中获取要在模板中呈现的数据。您要使用哪个 url 以及您在视图中使用哪个模板都没有关系。这意味着你可以有不同的 urls 指向同一个模板（www.example.com/blog/ 或 www.example.com/programming/）并且两者都渲染相同的模板。
如果我没看错，你只需要改变这个：
url(r'^$', views.post_list, name='post_list'),
url(r'^programowanie/$', views.programowanie, name='programowanie'),
为此：
url(r'^$', views.post_list, name='post_list'),
url(r'^programowanie/$', views.post_list, name='programowanie'),
您可以参考 Django 官方网站以获得更多相关信息：https://docs.djangoproject.com/en/2.0/intro/tutorial03/
