Rails：自定義驗證消息

Question

我試圖做一個簡單的自定義驗證消息。驗證我使用的編譯和運行良好，但我沒有看到郵件中的任何改變：

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

我需要驗證rating是目前和decimal之間0-5

Answer 1

好吧，我解決了它。這是工作的驗證：

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

，我在這裏加入此

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