Geek asks and answers

How does a satellite work?

This question relates to ligaments, rubigems, and how it determines which method I call. It's quite a long time, so please bear with me.

According to my understanding, Bundler is a dependency management tool for managing ruby ​​gemstones. He sets all the gems and their dependencies listed in Gemfile.

The question I want to ask can be best illustrated with an example. so here -> In my rails application, I do this in my controller: -

module SurveyorControllerCustomMethods
  def create
    super
  end
end
class SurveyorController < ApplicationController
   include Surveyor::SurveyorControllerMethods
end

Here I do two things:

  • Turn on SurveyorControllerMethodsfrom Surveyor camcorder.
  • Since I used super here, it would call a method createfrom SurveyorControllerMethodsthat works fine, but I do not understand this.

and the gem is set to

$ bundle show surveyor
/home/gaurish/.rvm/gems/ruby-1.9.3-p194/gems/surveyor-0.22.0

ruby ​​$LOAD_PATH. :
