Question

I am trying to learn how to use a hyperlink in a view to access a custom controller method. I have the following code in my Controller, and I would like to access this with a link_to command in a View. I’m guessing there is something I need to do in the routes file to make the launch_build_file method work? What code should I list in the View to trigger the launch_build_file method?

class ReportsController < ApplicationController

  def index
  end

  def launch_build_file
    Process.spawn("ruby #{Rails.root}/lib/build.rb")
  end

end

In your routes file suppose you have reports resource,if not then you can use named routes

resources :reports do

 collection do
  get :launch_build_file
 end


end
#or
match '/reports/launch_build_file' => "reports#launch_build_file", :as => 'launch_build_file'

#If it's collection route 
link_to launch_build_file_reports_path
#or 
link_to launch_build_file_path
