使用Rails一次进行服务器和客户端验证

Question

The goal

Creating model's validation once and use it both for the model and for the view.

The problem

I don't know the way.

The scenario

I'm creating an application in Ruby on Rails and I want to indicate that User's e-mail always will require at least 6 characteres to vaildate it, and I want to use that rule for client-side and server-side.

What I actually need

A light. A start. I just have the user in the database and the model in Rails.

How to?

Answer 1

There is a gem client_side_validations which is no longer being maintained but appears to do what you want. ( github link )

Answer 2

Its better to use rails4_client_side_validations. It supports rails 4 also. rails4_client_side_validations
