Ruby on rails rails—有关验证的问题

我在验证方面有问题 有课
/app/models/group.rb

class Group < AbstractModel
  include Localized::Title

  ...

end

当我尝试在模型中使用验证时，它是有效的，但不需要担心。 请帮帮我，我做错了什么

p.S.AbstractModelrails 4.2、ruby 2.2.0p0

它是“包含”而不是“包含”。试着这样做：

module Localized::Title
  extend ActiveSupport::Concern
  include ActiveModel::Validations

  included do 
    validates :title_ua, length: {minimum: 3, maximum: 200}, uniqueness: true
    validates :title_ru, length: {minimum: 3, maximum: 200}, uniqueness: true
  end

...

end

module Localized::Title
  extend ActiveSupport::Concern
  include ActiveModel::Validations

  included do 
    validates :title_ua, length: {minimum: 3, maximum: 200}, uniqueness: true
    validates :title_ru, length: {minimum: 3, maximum: 200}, uniqueness: true
  end

...

end
