Reading RAILS forces you to learn

or rather reading open source code in general

You Don't know
What you Don't KNow

# rails/actionpack/lib/action_dispatch/testing/integration.rb

%w(get post patch put head delete cookies assigns
   xml_http_request xhr get_via_redirect post_via_redirect).each do |method|
  define_method(method) do |*args|
    # reset the html_document variable, except for cookies/assigns calls
    unless method == 'cookies' || method == 'assigns'
      @html_document = nil
      reset_template_assertion
    end

    integration_session.__send__(method, *args).tap do
      copy_session_variables!
    end
  end
end

Rails is such a large code base, How can I possibly contribute anything
