从gem调用方法后,如何从dependencies.rb调用方法?

标签: ruby-on-rails debugging activesupport

为了了解更多有关Ransack(Gem)如何工作的信息,我开始调试它,这会带我进入控制台:

   28:   def index
   29:     debugger
=> 30:     @search = ControlCenter.ransack(params[:q])

我想要更深入,所以我输入

(byebug) step

给了我这个输出:

[197, 206] in /Users/xx/.rvm/gems/ruby-2.3.0@xxx/gems/activesupport-5.0.0.1/lib/active_support/dependencies.rb

   201:       def const_missing(const_name)
=> 202:         from_mod = anonymous? ? guess_for_anonymous(const_name) : self
   203:         Dependencies.load_missing_constant(from_mod, const_name)
   204:       end

查看搜索方法:

def ransack(params = {}, options = {})
  Search.new(self, params, options)
end

我无法理解这里发生了什么。两者之间没有电话吗?我如何以ActiveSupport :: Dependencies结束?我没有跟step的每次通话都没有?
