Restful Orders Routing example

orders.rb

##
## RESTful routes for an 'orders' resource
#
# Note: In order to use the 'other' HTTP verbs (put & delete) you need to enable the
# method_override feature of Sinatra.
#
# (in config/environment.rb)
# config do
#   set :method_override, true
#
# end
#
# Don't forget to include the hidden _method input on forms
# you want to use a non-get/post http verb. e.g.
#
# <form action="/orders/<%=@order.id%>" method="post">
#   <input type="hidden" name="_method" value="delete"/>
#
#   <input type="submit" value="Delete Order with id: <%=@order.id%>"/>
# </form>
