Problem with active resource(500 internal server error)

Hi,

I have a rails server running. I wanted to connect to this using
activeresource.

Executing this code
Class Buildclient < ActiveResource::Base
  self.site = "http://localhost:3000/builds"
end

builds = Buildclient.find(:all)
puts builds (## printed nil)

On the rails server terminal i see

Started GET "/builds/buildclients.json" for 127.0.0.1 at Fri Jun 15
10:34:05 -0700 2012
Processing by BuildsController#show as JSON
  Parameters: {"id"=>"buildclients"}
  build Load (0.2ms) SELECT `builds`.* FROM `builds` WHERE
`builds`.`id` = 0 LIMIT 1
Completed 500 Internal Server Error in 1ms

ActiveRecord::RecordNotFound (Couldn't find Build with id=buildclients):
  app/controllers/builds_controller.rb:17:in `show'

Why did the parameters id=>buildclients go? And why did i get an 500
internal server error.

Your request doesn't match your app's routing. Look at the output
of `rake routes` and compare to how you're making the request.

Maybe re-reading <http://guides.rubyonrails.org/routing.html> will
help clarify...
