Question

我想将主页上的帖子列表添加到另一个子页面。（主页到子页面称为“ programowanie”）

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帖子列表（我可以使用管理面板添加，删除帖子）。问题是，当我尝试将模板从具有发布列表的起始页面复制到其他子页面（称为：www.example.com/programowanie）时，它不起作用（我从主页上看到了一个模板，但没有发布列表）我认为问题出在模板{blog / post / list.html}中，循环{％为帖子％}
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部分以仅在“ programowanie”子页面中发布帖子。

这是我的文件： blog / views.py

感谢您的帮助！（我在想这第三天）

Answer 1

问题出在视图中。

Django模板必须由一个视图呈现，从该视图可以获取要在模板中呈现的数据。在视图中使用哪个url和使用哪个模板都没有关系。这意味着您可以拥有指向同一模板的不同网址（www.example.com/blog/或www.example.com/programming/），并且它们都呈现相同的模板。

如果我没看错，您所要做的就是更改此内容：

url(r'^$', views.post_list, name='post_list'),
url(r'^programowanie/$', views.programowanie, name='programowanie'),

对此：

url(r'^$', views.post_list, name='post_list'),
url(r'^programowanie/$', views.post_list, name='programowanie'),

您可以访问Django官方网站，以获取有关以下内容的更多信息：https://docs.djangoproject.com/en/2.0/intro/tutorial03/
