Rails:自定义验证消息 [英] Rails: Custom validation message

问题描述

我正在尝试制作一个简单的自定义验证消息.我正在使用的验证编译并运行良好，但我没有看到消息中有任何变化:

I'm trying to make a simple custom validation message. The validation I'm using compiles and runs fine, but I don't see any change in the message:

验证 :rating, :inclusion =>{ :in =>0..5 }, :presence =>{:消息=>" 必须在 0-5 之间" }

我得到的消息仍然是评分未包含在列表中

我需要验证 rating 是否存在并且是 0-5

I need to validate that rating is present and is a decimal between 0-5

推荐答案

好的，我解决了.这是有效的验证:

Alright, I solved it. This is the validation that works:

validates :rating, :inclusion => { :in => 0..5, :message => " should be between 0 to 5" }
validates :rating, :presence => { :message => " cannot be blank" }

我添加了这个

验证 :rating, :numericality =>{:消息=>"应该是一个数字" }
