Java 使用Play Framework 2使用动态创建的表单输入更新数据库

我有一个候选人模型和一堆其他模型，如学校、学位、技能、工作岗位等，它们与候选人模型有一对多的关系

我能够创建一个create表单（创建新候选表单的表单），该表单可以使用javascript/jquery动态创建表单字段。用户可以通过单击“添加其他按钮”添加更多输入字段。表单提交给控制器，所有数据都完美地添加到数据库中

这个问题在编辑表单中起作用。编辑表单与创建表单几乎相同，只是它在数据库的表单字段中预先填充了数据。当我将此表单提交到控制器中的更新函数时，它会错误地执行更新。当我返回到编辑表单查看它是否正常工作时，有一些带有空白值的随机输入字段，但数据确实得到了编辑

我对游戏框架相当陌生，可能做错了什么。我使用Codeigniter在PHP中做了类似的事情，效果很好。可能是因为Codeigniter不使用Ebean或JPA

下面是我写的一些代码，所以我的问题更容易理解。我只打算包括候选人模型和学校模型，因为其他模型与学校模型相似。此外，我还包含了生成动态表单字段的js代码

任何帮助都将不胜感激
