Rails，编写模块。存储设置在哪里？

Question

我有模特行为。

我想像这样包括：

class Building < ActiveRecord::Base
    has_many :blocks
    include Staticizable
    check_children :blocks #here name of children model to check
    ...
end

行为看起来像：

module Staticizable
    extend ActiveSupport::Concern
    module ClassMethods
        def check_children child
            self.child_model = child #where is to store model name to check?
        end
    end

    def was_staticized
        (DateTime.now - self.staticized_date.to_datetime).to_i
    end

    def staticized?
        if @child_model.present?
            ap self.send(@child_model)
        else
            if staticize_period > was_staticized
                true
            else
                false
            end
        end
    end

    def staticized
        self.staticized_date = DateTime.now
        save
    end
end

所以我需要知道在哪里可以存储型号名称以检查 children。做这样的事情的正确方法是什么？

终于找到答案了，不确定是不是最好的方法，如果不是，请告诉我：

module Staticizable
    extend ActiveSupport::Concern

    included do
        class << self;
            attr_accessor :has_child_custom
        end
    end

    module ClassMethods
        def check_children child
            self.has_child_custom = child
        end
    end

    def was_staticized
        unless staticized_date
            return false
        end
        (DateTime.now - self.staticized_date.to_datetime).to_i
    end

    def staticized?
        if self.class.has_child_custom.present?
            self.send(self.class.has_child_custom).each do |child|
                unless child.staticized?
                    return false
                end
            end
        else
            if self.staticize_period > was_staticized
                true
            else
                false
            end
        end

    end

    def staticized
        self.staticized_date = DateTime.now
        save
    end

end

我还在 /config/initializers 中使用

创建了一个文件

ActiveRecord::Base.send :include, Staticizable

并在模型中设置：

class Building < ActiveRecord::Base
    check_children :blocks
    ...
end

Rails，编写模块。存储设置在哪里？

Rails, writing module. Where is to store setting?
