Cakephp 2.x multiple relationship

Question

i have some troubles with cakephp 2.x and the relationship of the models, i have 3 models, Post, User and Comment. I would like bind the Post with his User and Comment with his User.

In Post Model:

   $belongsTo = array('Comment','User'),
   $hasMany = array('CommentOfPost'=>array('className'=>'Comment'));

I have Post bind with User, and all comment from the post but i don't have users of the comments.

Edit :

Sql output

   1    SELECT `Post`.`id`, `Post`.`title`, `Post`.`content`, `Post`.`tags`, `Post`.`created`,  `Post`.`modified`, `Post`.`user_id`, `User`.`id`, `User`.`username`, `User`.`password`, `User`.`role`, `User`.`name`, `User`.`lastname`, `User`.`birthdate`, `User`.`email`, `User`.`created`, `User`.`modified` FROM `blog`.`posts` AS `Post` LEFT JOIN `blog`.`users` AS `User` ON (`Post`.`user_id` = `User`.`id`) WHERE `Post`.`id` = 16 LIMIT 1        1   1   0
   2    SELECT `CommentOfPost`.`id`, `CommentOfPost`.`post_id`, `CommentOfPost`.`user_id`, `CommentOfPost`.`content`, `CommentOfPost`.`created` FROM `blog`.`comments` AS `CommentOfPost` WHERE `CommentOfPost`.`post_id` = (16)

Edit : Comment Model

    public $belongsTo = array('User' => array('className' => 'User'));

Post Model

    public $belongsTo = array('Comment' => array('className' => 'Comment'));

Edit :

Thank for reply, i have the same result like before i have Post and his User and Post and his comments but not users of comments

Now my model Post

    $hasMany = array(
            'Comment' => array(
                'className' => 'Comment',
            )
        ),
        $belongsTo = array(
            'User' => array(
                'className' => 'User',
            )
        );

User model

   $hasMany = array('Comment' => array('className' => 'Comment'));

Comment Model

   $belongsTo = array('Users' => array('className' => 'User'), 'Posts' => array('clasName' => 'Post'));

I use paginate querying in my PostsController

    $this->Paginator->settings = $this->paginate;

    $data = $this->Paginator->paginate('Post');
    $this->set('posts', $data);

Edit :

My paginate params

    $paginate = array(
    'limit' => 10,
    'recursive' => 2,
    'order' => array(
        'Post.id' => 'desc'
    )
);

I try with and without recursive option

Ok it's done !

For resume i have :

   class User extends AppModel {
       public $hasMany = array('Comment' => array('className' => 'Comment'));
   }

   class Post extends AppModel 
   {
       $hasMany = array(
            'Comment' => array(
                'className' => 'Comment',
            )
        ),
        $belongsTo = array(
            'User' => array(
                'className' => 'User',
            )
        );
    }

    class Comment extends AppModel {
        public $belongsTo = array('User' => array('className' => 'User'), 'Post' => array('clasName' => 'Post'));

}

    PostsController extends AppController
    {
        ....

        $this->Post->recursive = 2;
        $post = $this->Post->findById($id);

        ...
    }

Thank for your help guys, you're awesome !

Answer 1

Post does not belongs to Comment . It has many comments .

http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html

Example from the cookbook:

class User extends AppModel {
    public $hasMany = array(
        'MyRecipe' => array(
            'className' => 'Recipe',
        )
    );
}

For your application:

class Post extends AppModel {
    public $hasMany = array(
        'Comment' => array(
            'className' => 'Comment',
        )
    );

    public $belongsTo = array(
        'User' => array(
            'className' => 'User',
        )
    );
}
