$ rails console
Loading development environment (Rails 3.0.6)
ruby-1.8.7-p334 :001 > r = Rails.application.routes

Gives you a handle of all the routes (config/routes.rb)

#Inspect a named route:

ruby-1.8.7-p334 :005 > r.recognize_path(app.destroy_user_session_path)

If you are build a saas, using VMs and management tools. You will find vagrant is useful for additional features.

But Virtual machines take too much time to load. Now there is a new trending called using docker. Docker is written in go, if you haven't heard of, you should probably go to check it out. In this article I am going to run a docker container in vagrant virtual machine

What is vagrant

Vagrant is a tool for building complete development environments. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases development/production parity, and makes the "works on my machine" excuse a relic of the past.
