Question

I am new to ruby on rails and trying to build an internal site to manage
several ruby scripts. What I am trying to accomplish; create web page
where an user clicks on a link (Execute Analyzer) to execute ruby script
(runs in the background – FitAnalyzer.rb). I am having trouble
understanding how to route this without redirecting to another web page.
I basically need help how to add the correct format to routes.rb.

analyzer.html.erb

<%= link_to "![Execute][1] Analyzer", :controller =>
'fit_anlayzer_controller', :method => 'execute_analyzer'%>

fit_analyzer_controller.rb

class FitAnalyzerController < ApplicationController
  def analyzer
  end

  def execute_analyzer
    # Delayed::Job.enqueue(AnalyzerJob.new(params[:id]), 3)
    # command = 'ruby ~/ruby_scripts/fit_analyzer/FitAnalyzer.rb'
    @execute_command = system 'ruby
/Users/gsypolt/rubyqa_project/ruby_scripts/fit_analyzer/FitAnalyzer.rb'
    flash[:notice] = "Executing FitNesse Analyzer"
  end
end

When accessing mylocalhost/fit_analyzer/analyzer receiving
this message below

No route matches {:controller=>"fit_anlayzer_controller",
:method=>"execute_analyzer", :popup=>true}

I have been learning ruby on rails from lyndia.com and book (rails 3
way)

You need to add a route

# config/routes.rb
match "fit_analyzer/analyzer" => 'fit_analyzer#execute_analyzer'

The fit_analyzer#execute_analyzer corresponds to controller#action

Then you need to call it using ajax. To do that add a :remote => true to your link_to
