python - 我正在合并多个表单，并在 django 的注册表单中获取 ValueError/，同时链接到另一个表单数据库

问题描述

[这是使用 print 来检查的更新代码][1]我得到了ValueErrorat /Register。错误是：

The view Capp.views.Insertrecord didn't return an HttpResponse object. It returned None instead.

我正在合并各种html形式。即使检查了变量，它到处都是一样的。我在models.py此处附上了 [ ] 图片以供参考。所有表格都可以正常工作，但是在单击注册表单的提交按钮后，发生了此错误。 视图.py
