Rails：自定义验证消息

Question

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：

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

我收到的消息还是Rating is not included in the list

我需要验证rating 是否存在并且是0-5 之间的decimal

Answer 1

好的，我解决了。这是有效的验证：

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

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