Rails：自定義驗證消息

Question

我正在嘗試制作一個簡單的自定義驗證消息。 我正在使用的驗證編譯並運行正常，但我沒有看到消息有任何變化：

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

我收到的消息仍然是Rating is not included in the list

我需要驗證rating是否存在，並且是0-5之間的decimal

Answer 1

好吧，我解決了。 這是有效的驗證：

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

我添加了這個

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