包含验证的自定义错误消息

Question

我正在使用包含验证

validates :field_type, :inclusion => %w(SA LA RB CB SB Date)

现在当验证被解雇时，我得到了"Field type is not included in the list"。这对我没有任何意义。所以，我希望有自己的自定义消息说"This value is not included in Field Type."任何人都可以在这里指导我吗？

Answer 1

我想你想要：

validates :field_type, :inclusion => { :in => %w(SA LA RB CB SB Date),
                                       :message => "The value: %{value} is not included in Field Type." }

请参阅this post.

Answer 2

尝试消息选项

validates :field_type, :inclusion => %w(SA LA RB CB SB Date), :message => "...."
