talking REST with json payload... first curl and then activeresource

gistfile1.txt

#Please excuse the naming of things, this is a on the fly contrived example

curl -i -H "Content-Type: application/json" -H "Accept: application/json"  
-X POST -d '{"a_request":{"thing_ids":[1,2,3,4]}}' http://localhost:3000/a_requests


produces....

Started POST "/a_requests" for 127.0.0.1 at 2011-06-16 11:53:21 -0400
  Processing by ARequests#create as JSON
  Parameters: {"a_request"=>{"thing_ids"=>[1, 2, 3, 4]}}
.....

and now the encapsulation with ActiveResource:

class ARequest < ActiveResource::Base

  self.site = "http://localhost:3000"

end

ARequest.create :thing_ids => [1,2,3,4]
