php - Codeigniter Restful API not working -


i have codeigniter setup installed restful api thing. created api-folder in application->controller->api , after created api looks this:

<?php  require(apppath.'libraries/rest_controller.php');  class allartists extends rest_controller{  function artists_get() {     if(!$this->get('artist_id'))     {         $this->response(null, 400);     }      $artists = $this->artist_model->get( $this->get('artist_id') );      if($artists)     {         $this->response($artists, 200);     }     else     {         $this->response(array('error' => 'couldn\'t find artists!'), 404);     } }  ?>

in application->models-folder have file artist_model.php looks this:

<?php  class artist_model extends ci_model {    function get_all_artists(){     $this->db->select('*');     $this->db->from('artists');     return $this->db->get();    } }  ?>

so, when type http://localhost/myprojects/ci/index.php/api/allartists/artists/ 400 - bad request-error... when type http://localhost/myprojects/ci/index.php/api/allartists/artists/artist_id/100 php error undefined property: allartists::$artist_model - going on here?

you need load model. add constructor allartists , load it.

class allartists extends rest_controller{     function __construct(){         parent::__construct();         $this->load->model('artist_model');     }      // ... }

p.s. model needs have 1st letter in class name capitalized (see: http://ellislab.com/codeigniter/user-guide/general/models.html):

class artist_model extends ci_model{     // ... }

update: looking $this->get('artist_id'). never set not sending $_get['artist_id'] value (?artist_id=100 in url). need $artist_id way in controller.

function artists_get($artist_id=false) {     if($artist_id === false)     {         $this->response(null, 400);     }      $artists = $this->artist_model->get( $artist_id );      if($artists)     {         $this->response($artists, 200);     }     else     {         $this->response(array('error' => 'couldn\'t find artists!'), 404);     } }

then go to:

http://localhost/myprojects/ci/index.php/api/allartists/artists/100

or, keeping current code, change url to:

http://localhost/myprojects/ci/index.php/api/allartists/artists?artist_id=100
