I'm having some trouble with CakePHP's models.
I have three tables - CC_PLAYLIST, CC_PLAYLISTCONTENTS, and CC_FILES.
I'd like to get a list of all playlists, with all of their contents, and then the relevant file information for each piece of playlist content.
I.E
Playlist 1
-- Playlist Content 1
---- File Info
-- Playlist Content 2
---- File Info
-- Playlist Content 3
---- File Info
Playlist 2
-- Playlist Content 123
---- File Info
In my controller I have:
$playlistcontent = $this->AirtimePlaylist->find('all') however that seems to turn up a flat array with all playlistcontents, all files, and empty playlist arrays.
AirtimeFile.php
class AirtimeFile extends AppModel {
public $useTable = 'cc_files';
public $actsAs = array('Containable');
public $hasMany = array('AirtimeFileAttribute' => array(
'className' => 'AirtimeFileAttribute',
'foreignKey' => 'track_id'
));
}
AirtimePlaylist.php
class AirtimePlaylist extends AppModel {
public $useTable = 'cc_playlist';
public $actsAs = array('Containable');
public $hasMany = array('AirtimePlaylistContent' => array(
'className' => 'AirtimePlaylistContent',
'foreignKey' => 'playlist_id'
));
}
AirtimePlaylistContent.php
class AirtimePlaylistContent extends AppModel {
public $useTable = 'cc_playlistcontents';
public $actsAs = array('Containable');
public $hasOne = array('AirtimePlaylist' => array(
'className' => 'AirtimePlaylist',
'foreignKey' => 'id'
),'AirtimeFile' => array(
'className' => 'AirtimeFile',
'foreignKey' => 'id'
));
}
In your controller you need to use contain
$model = $this->AirtimePlaylist->find('all',
array(
'contain' => array('AirtimePlaylistContent' => array('AirtimeFile') )
)
);

I'm having a very strange issue. I'm working with XAMPP on my local computer, and everything works perfect. But when I upload it to my server, suddenly ContainableBehavior stops recognizing associations.
Cake's version: 2.5.6
Here's XAMPP's phpinfo(): http://pastebin.com/DeZWMh42
And here's my server's phpinfo(): http://pastebin.com/rtZ0kTAM
Both locations have the exact same files and databases.
This is the error(s) I'm getting:
Warning (512): Model "Certificado" is not associated with model
"Usuario" [CORE/Cake/Model/Behavior/ContainableBehavior.php, line 342]
Warning (512): Model "Certificado" is not associated with model
"Alumno" [CORE/Cake/Model/Behavior/ContainableBehavior.php, line 342]
Warning (512): Model "Certificado" is not associated with model
"Usuario" [CORE/Cake/Model/Behavior/ContainableBehavior.php, line 342]
Warning (512): Model "Certificado" is not associated with model
"Alumno" [CORE/Cake/Model/Behavior/ContainableBehavior.php, line 342]
Basically, an Impresion belongs to an Usuario and to a Certificado, the latter also belongs to an Usuario (may be a different one) and to an Alumno. Obviously I cut out all the irrelevant parts (let me know if you need more.)
This is where I'm using ContainableBehavior (Impresion's Controller):
(I'm getting the error on /impresions/index)
class ImpresionsController extends AppController {
public $components = array('Paginator');
public $uses = array('Usuario', 'Alumno', 'Certificado', 'Impresion');
public function index(){
$this->paginate = array(
'limit' => 10,
'order' => array('fecha_creacion' => 'desc'),
'contain'=>array(
'Usuario',
'Certificado' => array(
'Usuario',
'Alumno'
)
),
);
$results = $this->paginate('Impresion');
$this->set('impresiones',$results);
}
}
And in the view I just use a foreach($impresiones).
Impresion's Model:
class Impresion extends AppModel {
public $actsAs = array('Containable');
public $belongsTo = array(
'Certificado' => array(
'className' => 'certificado',
'foreignKey' => 'certificado_id',
),
'Usuario' => array(
'className' => 'Usuario',
'foreignKey' => 'usuario_id',
'fields' => array('nombre','codigo')
),
);
}
Usuario's Model:
class Usuario extends AppModel {
public $hasMany = array('Certificado','Impresion');
public $actsAs = array('Containable');
}
Certificado's Model:
class Certificado extends AppModel {
public $actsAs = array('Containable');
public $belongsTo = array(
'Usuario' => array(
'className' => 'Usuario',
'foreignKey' => 'usuario_id',
),
'Alumno' => array(
'className' => 'Alumno',
'foreignKey' => 'alumno_id',
)
);
public $hasMany = 'Impresion';
}
Alumno's Model:
class Alumno extends AppModel {
public $actsAs = array('Containable');
public $hasMany = 'Certificado';
}
Local query: http://pastebin.com/B5MRp3FS
Server's query: http://pastebin.com/J2H4U6Ge
I'm completely lost here. Why does it work perfectly fine on my computer, but breaks on the server? Everything else works, it's just ContainableBehavior that's having problems.
I can't believe it.
Disregard everything.
This:
'className' => 'certificado',
Should've been this:
'className' => 'Certificado',
Sorry for wasting your time, I'm an idiot

Updated Question
I am trying to Join Multiple tables in CakePHP and retrieve their data.
I have created my Model but not getting relevant result.
Below is my Table Structure.
Fields needed :
Equipment Name
Equipment Description
Equipment Type name according to Equipment id
Equipment Type Sizes names according to Type id
Sizes Stock.
Model:Equipment.php
class Equipment extends AppModel {
public $useTable = 'equipments';
var $name = 'Equipment';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentSize',
'foreignKey' => 'equipment_id'
)
);
}
Model:EquipmentSizes .php
class EquipmentSizes extends AppModel {
public $useTable = 'equipment_sizes';
var $name = 'EquipmentSizes';
public $cacheQueries = false;
public $belongsTo = array(
'Equipment' => array(
'className' => 'Equipment',
'foreignKey' => 'equipment_id',
'fields' => array('id', 'sizes')
)
);
}
Model:EquipmentType.php
class EquipmentType extends AppModel {
public $useTable = 'equipment_types';
var $name = 'EquipmentType';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentTypesSize',
'foreignKey' => 'equipment_type_id'
)
);
}
Model:EquipmentTypesSizes.php
class EquipmentTypesSizes extends AppModel {
public $useTable = 'equipment_types_sizes';
var $name = 'EquipmentTypesSizes';
public $cacheQueries = false;
public $belongsTo = array(
'EquipmentType' => array(
'className' => 'EquipmentType',
'foreignKey' => 'equipment_type_id',
'fields' => array('id', 'sizes')
)
);
}
You have forgotten the foreign keys on some of your models (Equipment.php, EquipmentType.php) that have hasToMany relationship. Correct your models first then try to query an equipment and you can see there the associated models of Equipment. You can then base your conditions to that.
Updated - Equipment.php
class Equipment extends AppModel {
public $useTable = 'equipments';
var $name = 'Equipment';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentSize',
'foreignKey' => 'equipment_id'
),
'EquipmentType' => array(
'className' => 'EquipmentType',
'foreignKey' => 'equipment_id'
)
);
}
EquipmentSizes.php is correct.
Updated - EquipmentType.php
class EquipmentType extends AppModel {
public $useTable = 'equipment_types';
var $name = 'EquipmentType';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentTypesSize',
'foreignKey' => 'equipment_type_id'
)
);
public $belongsTo = array(
'Equipment' => array(
'className' => 'Equipment',
'foreignKey' => 'equipment_id'
)
);
}
EquipmentTypesSizes.php is correct.
Sorry if the Title misses what i'm aiming at, but had no clue how to name this. Here's my Quest:
I have a single Cart, holding multiple Items (1:n) which are belonging to prices (1:1).
The Relations between Items and Prices are working as well:
class Item extends AppModel {
public $hasOne = 'Price';
}
class Price extends AppModel {
public $belongsTo = array(
'Item' => array(
'className' => 'Item',
'foreignKey' => 'id'
)
);
}
But now i make a select (find) of a cart and want those items included, which is also working as well:
class CartItem extends AppModel {
public $useTable = 'cart_items';
public $belongsTo = array('Item', 'Address');
}
But what i really need is to get those prices of each item, which is not working ($result in afterFind()-Callback in Item-Model does not include the assigned prices & afterFind()-Callback in Price-Model is not called when finding a cart)..
what am i missing here?
/EDIT: Recent Changes:
class AppModel extends Model {
var $actsAs = array('Containable');
}
class CartsController extends AppController {
public function getCart() {
$cart = ClassRegistry::init('CartItem')->find('all', array(
'contain' => array(
'Item' => array(
'Price'
),
'Address'
),
'conditions' => array(
'id_cart' => $cart['Cart']['id']
)
));
}
The above changes cause that i'll get a Price into a found Item but only into the last one thats found.
You haven't shown your actual find(), but I suspect you're not setting an appropriate 'recursive' param or are not using 'contain'.
I prefer using the containable behaviour enabled from AppModel:
var $actsAs = array('Containable');
Then you can do something like:
$cartItem = $this->CartItem->find(
'first',
array(
'contain' => array(
'Item' => array(
'Price'
),
'Address'
),
'conditions' => array('CartItem.id' => 123)
)
);
My Category Model:
class Category extends AppModel {
public $displayField = 'name';
// public $actsAs = array('Containable');
public $hasAndBelongsToMany = array(
'Post' => array(
'className' => 'Post',
'joinTable' => 'categories_postss',
'foreignKey' => 'category_id',
'associationForeignKey' => 'post_id',
'unique' => 'keepExisting'
)
);
}
$params['contain'] = array('Post' => array(
'limit'=> 3));
pr($this->Category->find('first',$params)); exit;
It is fetching all Posts, irrespective of limit.
What I want to do:
I have this page where I ma listing all the categories and latest 5 posts related to it.
I want to limit the associated model to only 5 rows.
Any ideas?
Containable behavior is not in use
The most likely reason for this problem is that the containable behavior is not being used at all.
Compare, for the below code example:
$results = $this->Category->find('first', array(
'contain' => array(
'Post' => array(
'limit' => 3
)
)
));
Without containable behavior, it'll generate the following queries:
SELECT ... FROM `crud`.`categories` AS `Category` WHERE 1 = 1 LIMIT
SELECT ... FROM `crud`.`posts` AS `Post`
JOIN `crud`.`categories_posts` AS `CategoriesPost` ON (...)
With containable behavior, it'll generate the following queries:
SELECT ... FROM `crud`.`categories` AS `Category` WHERE 1 = 1 LIMIT
SELECT ... FROM `crud`.`posts` AS `Post`
JOIN `crud`.`categories_posts` AS `CategoriesPost` ON (...) LIMIT 3
Given this (and the code in the question) check that the AppModel has the containable behavior in $actsAs:
<?php
// app/Model/AppModel.php
class AppModel extends Model {
public $actsAs = array('Containable');
}
Limit always required?
Alternatively, or possibly in addition, you may prefer to put a limit in the association definition - To do so just define the 'limit' key:
class Category extends AppModel {
public $hasAndBelongsToMany = array(
'Post' => array(
'limit' => 100, // default to a high but usable number of results
)
);
}
the hasAndBelongsToMany relationship seems unnecessary to me. I think you only need Category hasMany Post and Post belongsTo Category relationships. Add category_id to the posts table. Make both models actAs containable.
Post Model
class Post extends AppModel {
public $actsAs = array('Containable');
var $belongsTo = array(
'Category' => array(
'className' => 'Category',
'foreignKey' => 'category_id'
),
// ... more relationships
);
Category Model
class Category extends AppModel {
public $actsAs = array('Containable');
var $hasMany = array(
'Post' => array(
'className' => 'Post',
'foreignKey' => 'category_id'
),
// ... more relationships
);
Categories Controller
class CategoriesController extends AppController {
public $paginate = array(
'Category' => array(
'contain' => array(
'Post' => array(
'limit' => 3
), // end Post
) // end Category contain
) // end Category pagination
); // end pagination
public function index() {
// for paginated results
$this->set('categories', $this->paginate());
// for find results
$this->Category->contain(array(
'Post' => array(
'limit' => 3
)
));
$this->set('categories', $this->Category->find('all'));
}
I'm using an existing database (I can't change it and its table names are not like cake conventions want it), and I'd like to do some left joins but can't do it properly :/
I've already defined my tables, giving them primary keys and the relations in the models.
Here is my problem :
Table Wysipage can have 0 to n wysipage_content, and 0 to n wysipage_menu.
an element from wysipage_content corresponds to 1 and only 1 Wysipage.
an element from wysipage_menu corresponds to 0 or 1 Wysipage.
I'd like to make a request who would give me a list of all the elements from Wysipages, with their eventuals contents and menus, all that in a single table, and by only one request.
Here are my tables definitions (I'm avoiding you the entire schema, just be aware there is a wp_id and a wp_name column) :
class Wysipage extends AppModel {
var $actsAs = array('Containable');
public $useTable = 'wysipage';
public $primaryKey = 'wp_id';
public $displayField = 'wp_name';
var $hasMany = array(
'un' => array(
'Wysipage_contenu' => array(
'className' => 'Wysipage_contenu',
'foreignKey' => 'wpc_wp_id',
)),
'deux' => array(
'Wysipage_menu' => array(
'className' => 'Wysipage_menu',
'foreignKey' => 'wpm_wp_id',
))
);
class Wysipage_contenu extends AppModel {
var $actsAs = array('Containable');
public $useTable = 'wysipage_contenu';
public $primaryKey = 'wpc_id';
public $displayField = 'wpc_h1';
public $belongsTo = array(
'Wysipage' => array(
'className' => 'Wysipage',
'foreignKey' => 'wp_id'
)
);
class Wysipage_menu extends AppModel {
var $actsAs = array('Containable');
public $useTable = 'wysipage_menu';
public $primaryKey = 'wm_id';
public $displayField = 'wm_lien';
public $belongsTo = array(
'Wysipage' => array(
'className' => 'Wysipage',
'foreignKey' => 'wm_wp_id'
)
);
And here is my code to try request (but failed) :
$this->loadModel('Wysipage_contenu');
$this->loadModel('Wysipage_menu');
$this->Wysipage->contain();
$mes_wysipages = $this->Wysipage->find('all', array('joins' => array(
array(
'table' => 'wysipage_contenu',
'alias' => 'wpc',
'type' => 'LEFT',
'conditions'=> array('wpc.wpc_wp_id = Wysipage.wp_id')
),
array(
'table' => 'wysipage_menu',
'alias' => 'wpm',
'type' => 'LEFT',
'conditions'=> array('wpm.wm_wp_id = Wysipage.wp_id')
)
)));
$this->set('wysipages', $mes_wysipages);
$this->render();
What have I done wrong? Is the problem in my model declarations? Or do I use a wrong request type? :(
The request I'd like to make is simply :
SELECT wp_id, wp_name, wpc_id, wpc_name
FROM wysipage
LEFT JOIN wysipage_contenu ON wysipage.wp_id = wysipage_contenu.wpc_wp_id
Just this :(
I'm not even sure I want a LEFT join or a RIGHT join, but anyway the problem remains the same, this code gives me bad answers with multiple occurrences of the same lines :/
Thanks :/
PS : Sorry for my bad English, it's not my native language.
You can not join content and menu tables on wp_id in same query because they both have many-to-one relationship to wp_id, and there by for each row from content there are all rows from menu with same wp_id in result of such join. You need to do 2 queries: one for content and one for menu. Or if list columns you needed identical for both tables you can union both results from this two queries.
