Rails：自定义验证消息

Question

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良好，但我没有看到邮件中的任何改变：

validates :rating, :inclusion => { :in => 0..5 }, :presence => { :message => " must be within 0-5" }

的消息我得到的仍然是Rating is not included in the list

我需要验证rating是目前和decimal之间0-5

Answer 1

好吧，我解决了它。这是工作的验证：

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

，我在这里加入此

validates :rating, :numericality => { :message => " should be a number" }
