Rails 3 UJS干客户端+服务器端表单验证 [英] Rails 3 UJS dry Client + Server Side form validation

问题描述

使用jQuery进行表单验证就像将类名添加到字段一样容易.使用rails进行表单验证就像将条件放入控制器(和/或模型)一样容易.

Form validation with jQuery is as easy as adding a classname to a field. Form validation with rails is as easy as putting a condition in to your controller (and/or model).

我认为应该有一种方法可以编写一次验证，并将验证应用于客户端和服务器端.我一直是我自己编写JavaScript的爱好者，但是如果使用rails3不引人注目，那么UJS如果可以做到这一点，可能就很值得了.

I figure there should be a way to write the validations once and have them applied both client and server side. I've always been a fan of writing my own javascript, but with rails3 unobtrusivity UJS might be well worthwhile here if it can accomplish this.

谢谢！
