Phalcon php orm can't relate tables -

i'm trying setup 3 tables relationship in phalcon, doesn't seem work. plese tell me doing wrong? here erd of these tables: (erd diagram) here code models , controller

authors.php (model)  <?php     class authors extends \phalcon\mvc\model {  /** *  * @var integer */ public $id;  /** * * @var string */ public $name;  /** * * @var string */ public $lastname;  /** * initialize method model. */ public function initialize() {   $this->setsource('authors');   $this->hasmany('id', 'authorbook', 'authorid'); }  /** * independent column mapping. */ public function columnmap() {   return array(       'id' => 'id',        'name' => 'name',        'lastname' => 'lastname'   ); } 

books.php(model)

<?php     class books extends \phalcon\mvc\model {   /**   *   * @var integer   */  public $id;   /**   *   * @var string   */  public $name;   /**   *   * @var string   */  public $yearpublished;   /**  *  * @var string  */  public $picture;  /**  * initialize method model.  */ public function initialize() {     $this->setsource('books');     $this->hasmany('id', 'authorbook', 'bookid'); }  /**  * independent column mapping.  */  public function columnmap()  {      return array(         'id' => 'id',          'name' => 'name',          'yearpublished' => 'yearpublished',          'picture' => 'picture'     );  }   }  } 

authorbook.php (model):

<?php  class authorbook extends \phalcon\mvc\model  {   /**    *   * @var integer   */  public $id;   /**   *   * @var integer  */ public $authorid;  /**  *  * @var integer  */ public $bookid;  /** * initialize method model. */ public function initialize() {   $this->setsource('authorbook');   $this->belongsto('authorid', 'authors', 'id');   $this->belongsto('bookid', 'books', 'id'); }   /**  *   independent column mapping.  */ public function columnmap() { return array(     'id' => 'id',      'authorid' => 'authorid',      'bookid' => 'bookid' ); }  } 

admincontroller.php

public function indexaction() {     $this->view->disablelevel(view::level_main_layout);     $this->view->setvar('books', books::find()->toarray()); }  } 

so question how can access author of book? because when print out books array in view thing :

array ( [0] => array (     [id] => 1     [name] => javascript: parts     [yearpublished] => 2014-04-18     [picture] => javascript-the-good-parts.jpg ) ... 

you should use hasmanytomany n-n relationship authors , books models, (if i'm not wrong, author has many books , books has many authors)

so models should this: authors:

public function initialize(){   $this->setsource('authors');   $this->hasmanytomany('id', 'authorbook', 'authorid', 'bookid', 'books', 'id', array( 'alias' => 'books' )); } 

same books model, have use hasmanytomany function:

public function initialize(){       $this->setsource('books');       $this->hasmanytomany('id', 'authorbook', 'bookid', 'authorid', 'author', 'id', array(     'alias' => 'authors'     ));     } 

the authorbook model relations correct.

now can author(s) of book simple call alias have defined in relations:

$book = books::findfirst(); $bookauthor = $book->authors->toarray() 

that's it.
