# To play with routes in the rails console from rails 3.1, use the following:
include Rails.application.routes.url_helpers
default_url_options[:host] = 'localhost:3000' # or whatever
# Now, can freely play with routes.
>> url_for User.first
=> "http://localhost:3000/users/7"
>> url_for [Pod.first, :tasks]
=> "http://localhost:3000/pods/8/tasks"
