更新表单验证同一页面上的其他表单而不是她自己（Flask）
Update form validates the other form on same page instead of herself (Flask)
我是 Flask 的新手，正在使用它创建我的第一个项目。我试图在同一页面上获取一些表格：上面用于创建会议的表格和 bootstrap 模态（更新、删除）中的其他 2 个表格，用于 table 中的每一行。创建表单和删除表单工作正常，但问题是当我使用更新表单时。我想在表单中包含 object 中的值，以便轻松更新它们。我不知道为什么，但是当我尝试更新会议并点击提交（“保存更改”）时，表单会使用更新表单中的值提交“create_form”。有趣的是，我得到了创建用户的另一个页面（相同的方法 - 3 种形式（2 种带有模态）和 .validate_on_submit 在同一路线），并且一切正常（更新形式不提交创建表格）。我认为 .validate_on_submit() 足以区分这两种形式的用法，但现在我很困惑。我应该分离代码，并为更新和删除创建新的路由，还是还有其他事情要做？
这是代码。
