# Padrino provides advanced routing definition support to make routes and

# aliases and easy access to url paths. The benefits of this is that instead
# of having to hard-code route urls into every area of your application, now
# we can just define the urls in a single spot and then attach an alias
# which can be used to refer to the url throughout the application.

# Method for organize in a better way our routes.
#
# @param [Array] args
# Controller arguments.
#
# @yield []
# The given block will be used to define the routes within the
# Controller.
#
# @example
# controller :admin do
# get :index do; ...; end
# get :show, :with => :id do; ...; end
# end
#
# url(:admin_index) # => "/admin"
# url(:admin_show, :id => 1) # "/admin/show/1"
#
# @example Using named routes follow the sinatra way:
# controller "/admin" do
# get "/index" do; ...; end
# get "/show/:id" do; ...; end
# end
#
# @example Supply +:provides+ to all controller routes:
# controller :provides => [:html, :xml, :json] do
# get :index do; "respond to html, xml and json"; end
# post :index do; "respond to html, xml and json"; end
# get :foo do; "respond to html, xml and json"; end
# end
#
# @example Specify parent resources in padrino with the +:parent+ option on the controller:
# controllers :product, :parent => :user do
# get :index do
# # url is generated as "/user/#{params[:user_id]}/product"
# # url_for(:product, :index, :user_id => 5) => "/user/5/product"
# end
# get :show, :with => :id do
# # url is generated as "/user/#{params[:user_id]}/product/show/#{params[:id]}"
# # url_for(:product, :show, :user_id => 5, :id => 10) => "/user/5/product/show/10"
# end
# end
#
# @example Specify conditions to run for all routes:
# controller :conditions => {:protect => true} do
# def self.protect(protected)
# condition do
# halt 403, "No secrets for you!" unless params[:key] == "s3cr3t"
# end if protected
# end
#
# # This route will only return "secret stuff" if the user goes to
# # `/private?key=s3cr3t`.
# get("/private") { "secret stuff" }
#
# # And this one, too!
# get("/also-private") { "secret stuff" }
#
# # But you can override the conditions for each route as needed.
# # This route will be publicly accessible without providing the
# # secret key.
# get :index, :protect => false do
# "Welcome!"
# end
# end
#
# @example Supply default values:
# controller :lang => :de do
# get :index, :map => "/:lang" do; "params[:lang] == :de"; end
# end
#
# In a controller before and after filters are scoped and didn't affect other controllers or main app.
# In a controller layout are scoped and didn't affect others controllers and main app.

# controller :posts do
# layout :post
# before { foo }
# after { bar }
