在类中包含模块并执行代码

这是我以前上过的一门课

class Something
    # Defines the validates class methods, which is called upon instantiation
    include Module

    validates :name
    validates :date

end

我现在有几个对象使用相同的功能,更糟的是,有几个对象定义了类似的东西,如:

class Anotherthing
    # Defines the validates class methods,  which is called upon instantiation
    include Module

    validates :age

end

我想“重用”这些类的内容,因此我将它们转换为模块:

module Something
    # Defines the validates class methods  which is called upon instantiation
    include Module

    validates :name
    validates :date

end

module Anotherthing
    # Defines the validates class methods which is called upon instantiation
    include Module

    validates :age

end

现在我可以创建一个类

class ADualClass
   include Something
   include Anotherthing
end

我的问题是,当我创建一个ADualClass对象时,不会调用validates方法…似乎“验证:事物”从未被调用过。为什么会这样?我该怎么强制?
