我试图创建一个博客的标题和描述的形式和照片创建内联在admin admin StackedInline。到目前为止，一切都工作正常，包括带有帖子列表的list.html页面，但是detail.html页面将所有帖子返回到一个页面上。如何解决?这个页面包含评论，我在网上没有找到任何类似的。我希望detail.html页面只返回属于list.html中主标题的帖子

我认为错误是travel = views.py中的travel .objects.all()我该如何解决这个问题?
我通过改变来解决这个问题;
travel = Travel.objects.all()
travel = Travel.objects.all().filter(pk=id)
