引导模式中的Django Form POST问题

Question

我搜索这个问题已经好几天了。。。不幸的是，我找不到答案

我有一个视图（建筑物），我想添加/编辑具有模态的建筑物。使用当前代码，我可以添加新建筑。但是，由于我无法传递现有建筑的id（pk），因此无法更新它

我有两个视图：一个用于表格，另一个用于表单。我注意到，当我发布时，我的Building视图发布，而不是newBuilding视图

我试图在newBuilding视图中从kwargs获取pk，但在post方法中无法获取

唯一剩下的就是更新

让我分享我的代码

提前谢谢

我尝试在FormView上更新kwargs（因为我可以在那里编辑建筑id），但我无法访问POSThttps://imgur.com/G7UcmLo上的kwargs
