Python Django objects.all（）不显示任何内容

大家好！ 我只是开始一种django编程的方式，所以有时候真的会感到困惑

我试图显示数据库中的所有对象，但打开页面时，它只是空的

有添加的内容，我以前尝试过ListView，它对我有效。但是现在我需要像网格一样分解对象，这个方法有一个问题

非常感谢您的帮助

顺便说一句，如何显示你的对象，比如网格，而不是列表，使用引导等等

谢谢大家!

您正在迭代模板中名为

的所有帖子。但是您的视图不会发送任何名为
all_post
；它只发送
帖子
。您需要使用一致的名称。
ohhh。。。这是ListView的一个变量，我太不注意了，谢谢你的朋友！顺便问一下，你知道如何实现我的对象在网格中的样子吗？我不知道网格是什么意思，但如果你想的话，你可以在HTML中使用表标记。我的意思是，我需要在一行中动态显示几个对象。目前，在我的模板中，它们是按顺序一个接一个地列出的。您可能应该问一个新问题，并举例说明所需的输出。
