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

问题描述

我试图做一个简单的自定义验证消息。验证我使用的编译和运行正常，但我没有看到在邮件中的任何变化：

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：评级：包括=＆GT; {：在=＆GT; 0..5}：presence =＆GT; {：消息=＆GT; 必须在0-5}

我得到的消息仍是评级不包括在名单

我需要验证评级是present和之间十进制 > 0-5

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

推荐答案

好吧，我解决了这个问题。这是工作的验证：

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" }

和我说这

验证：评级：numericality =＆GT; {：消息=＆GT; 应该是一个数字}
