How i can use model in other model?

Load the CI instance into a variable, and load/access other models through it, like this:

Code:

<?php
class Posts extends Model {

  var $CI;

  function Posts() {
    parent::Model();
    // Assign CI instance to variable so it is available to all functions in this model
    $this->CI =& get_instance();
  }


  function getPostOrderId($id) {
    $result = dibi::fetchAll('SELECT * FROM posts JOIN users ON posts.user_id=users.user_id where POST_ID =%i',$id);
        
    // Load comments model from CI instance
    $this->CI->load->model('comments');
    // Call function in the comments model using the CI instance
    $comments = $this->CI->comments->getCommentsForPost($id);

    var_dump($comments);
    return $result;        
    }

}
?>
