Question

我对问题的验证有疑问有班级 /app/models/group.rb

class Group < AbstractModel
  include Localized::Title

  ...

end

/app/models/concerns/localized/title.rb

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

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

...

end

当我尝试在模型中使用验证时，它起作用，但不关心。请帮帮我，我做错了什么？

P.S。 AbstractModel＆lt;的ActiveRecord :: Base的， rails 4.2，ruby 2.2.0p0

Answer 1

它包含'不包含'。试试这样：

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
