使用Djang中的Formset更新和删除多个图像

Question

我是Django新手，所以请原谅我代码中的任何愚蠢错误。我用FBV做了一个多个图像的帖子。它工作得非常好，它的工作是在一篇文章中添加多个图像。现在我正在编辑文章，但是我在编辑文章时遇到了问题，我得到了下面的错误。在

AttributeError at /gangsters/edit/Scarface-the-story-of-Al-Capone/
'tuple' object has no attribute '_committed'
Request Method: POST
Request URL:    http://127.0.0.1:8000/gangsters/edit/Scarface-the-story-of-Al-Capone
Django Version: 1.11
Exception Type: AttributeError
Exception Value:    
'tuple' object has no attribute '_committed' 

简单介绍一下我的模型，假设我正在尝试制作一个web应用程序，允许用户写来自世界各地和不同时间段的歹徒（更像post模型）。有两种型号。歹徒和黑帮成员。歹徒有黑帮的外号钥匙

我的模型如下

^{pr2}$

以下是我的黑帮编辑视图.py

^{3}$

如果问题太长，我很抱歉。同样，我的gangster_edit视图不工作，并给出AttributeError错误。错误详细信息粘贴在上面。如果你一直读到这里，非常感谢你帮我解决这个问题
