Cakephp 2.x multiple relationship - php

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',
)
);
}
