CI and Phil Strugeons REST API

[eluser]moos3[/eluser]
Phil,
I have the example working. now trying to figure out the how the controller knows how to route stuff. I have created the following funciton in it but when I call /api/pastes/lists/format/xml it giving me a 404 below is my code.

Code:

<?php



require(APPPATH.'/libraries/REST_Controller.php');



class Api extends REST_Controller {



    function get_lists(){

        $this->load->model('languages');

        $data = $this->pastes->getLists();



        if($data){

            $this->response($data,200);

        }else{

            $this->response(NULL, 404);

        }

    }



    function paste_get(){

        if(!$this->get('id')){

            $this->response(NULL, 404);

        }



        $this->load->model('languages');

        $check = $this->pastes->checkPaste('id');

        if($check){

            $data = $this->pastes->getPaste('id',true);

        }else{

            $this->response(NULL, 404);

        }

        if($data){

            $this->response($data,200);

        }else{

            $this->response(NULL, 404);

        }

    }



}



?>

any help would be great, I have never done rest before so I'm trying to figure out this.
