I know the solutions is simple and might have something to do with the Containable behavior but I can't get it working. Without all the tries
This is the case. I'd like to display the Event details of an Event (eg. a conference). Each event takes place in a EventVenue and each EventVenue is located in a Country.
So in the Country Model the following is present:
public $hasMany = array(
'EventVenue' => array(
'className' => 'EventVenue',
'foreignKey' => 'country_id'
))
In the EventVenue model a BelongsTo association is made
public $belongsTo = array(
'Country' => array(
'className' => 'Country',
'foreignKey' => 'country_id'
))
And in the Event model a hasOne association is made
public $hasOne = array(
'EventVenue' => array(
'className' => 'EventVenue',
'foreignKey' => 'event_id',
))
What I want is to display the country name on the page that is renderd in the EventsController. I do get all the Event and EventVenue data but the associated Country for the venue is not retrieved.
The data is retrieved in the following way
$item = $this->Event->findBySlug($slug);
How can I also get the country name (eg. Netherlands) retrieved from the database? I tried something like this but that did not work:
$item = $this->Event->findBySlug($slug,array(
'contain' => array(
'Event' => array(
'EventVenue' => array(
'Country'
)
)
)
)
Try this:
$item = $this->Event->findBySlug($slug,array(
'contain' => array(
'EventVenue' => array(
'Country'
)
)
);
Update
Turns out findBy does not support Containable. You could use this to get the desired result:
$item = $this->Event->find('first',array(
'conditions' => array(
'Event.slug' => $slug
),
'contain' => array(
'EventVenue' => array(
'Country'
)
)
);
Oh and make sure you have this in the model: public $actsAs = array('Containable');
try this method:
$this->Event->recusive = 2;
$item = $this->Event->findBySlug($slug);
You need to set the recursive to 2 before you make the find, something like this
$this->Event->recursive = 2;
with this, you'll get the Event, the EventVenue and the Country on one shot
Hope it helps

I have a model Ranking which holds a contact_id and belongsTo Model Contact.
Model Contact has a costumer_id and belongsTo Model Costumer.
And hasMany Rankings.
There is also a Model Product which hasMany Ranking.
On a statistics page I select
$this->Product->recursive = 1;
$this->set('products', $this->Paginator->paginate())
;
and I get the array of
array(
'Product' => array(
'id' => '69',
),
'Ranking' => array(
(int) 0 => array(
'id' => '29',
'contact_id' => '9',
'product_id' => '69',
'ranking' => '9',
),
I would like to bind now the Contact and Costumer to the ranking based on the contact_id.
Is this manually possible via bindModel?
If yes, how can I do that?
I tried to set $this->Product->recursive = 1; to 2 and 3, but that select so many other things which I would need to clear with unbindModel... So I hope there is a smarter way of bind those model to get to the data...?
What you basically want to use is containable behavior. With this behavior you are able to filter and limit model find operations. You have the possibility to add this behavior on model level or at the controller to avoid side effects if the application has already grown to a complicated level.
Example from Cake-Book:
// Activate Containable Behavior on the fly in a controller
$this->User->Behaviors->load('Containable');
$this->User->contain();
$this->User->find('all', array(
'contain' => array(
'Profile',
'Account' => array(
'AccountSummary'
),
'Post' => array(
'PostAttachment' => array(
'fields' => array('id', 'name'),
'PostAttachmentHistory' => array(
'HistoryNotes' => array(
'fields' => array('id', 'note')
)
)
),
'Tag' => array(
'conditions' => array('Tag.name LIKE' => '%happy%')
)
)
)
));
Hope this gives you a push into the right direction.
using find it will get me the right data with this:
$this->set('products', $this->Product->find('all', array(
'contain' => array(
'Ranking' => array(
'Contact' => array(
'foreignKey' => 'contact_id',
'Customer' => array(
'foreignKey' => 'customer_id',
)
)
)
)
)));
When using the Paginator it looks like
$this->Paginator->settings['contain'] = array(
'Ranking' => array(
'Contact' => array(
'foreignKey' => 'contact_id',
'Customer' => array(
'foreignKey' => 'customer_id',
)
)
)
);
$this->Product->Behaviors->load('Containable');
$this->set('products', $this->Paginator->paginate());
Thanks so much!!
how to get name of (UserTransactionType.name) with Transaction.who_pay_fee_1,2,3 fields.
'user_transaction_type_id' works well but how to get the rest of fields work :(
//Transaction Model
public $belongsTo = array(
'UserTransactionType' => array(
'className' => 'UserTransactionType',
'foreignKey' => 'user_transaction_type_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
//UserTransactionType Model
public $hasMany = array(
'Transaction' => array(
'className' => 'Transaction',
'foreignKey' => 'user_transaction_type_id',
'dependent' => false,
))
This is the sample code for your controller:
$this->UserTransactionType->find('all',array(
'fields' => array('name'),
'contain' => array('Transaction')
)
);
If Models are associated you can specify in 'contain' which of them you want to get in the result.
If you want to have only some fields of related Model, you can determine them after 'Transaction' in 'contain' just like in the regular find() query:
'contain' => array('Transaction' => array('fields' => array('field_1',
'field_2') ))
But in your case, you don't need to specify fields, because by default you get all fields.
So no matter if you define or not fields "who_pay_fee_1,2,3" because if you use 'contain' by default you will get foreing_key - user_transaction_type_id.
I hope it's helpful
For people they like CakePhp :)
in Controller ->
get the list of 'UserTransactionType'
in View ->
after looping trough all the transactions; in Transaction Status column simply load the 'UserTransactionType'array and assign the number of array to $userTransactionTypes.
$userTransactionTypes[$transaction['Who_pay_fee_1']];
To be honest it was straight forward but needed a bit concentration :)
I have 3 models (User, Message and Tag) with the following relations:
User hasMany Message
Message belongsto User
Message HABTM Tag
Tag HABTM Message
If a User is logged in he might want to see all Message tagged with something.
$messages = $this->Message->find('all', array(
'conditions' => array("Message.user_id" => $this->uid),
'contain' => array(
'Tag' => array(
'conditions' => array(
'Tag.id' => $activetag['Tag']['id']
)
)
));
However, this find will return ALL messages of that user. (Containable behaviour is included in both models)
Containable on child (tag) does not perform filter on the parent (message), that's why all the messages are returned. The containable only place condition on the tag itself, in your case, messages not matching $activeTag would still get returned but with empty tag array attached, while messages matching would return with an array containing only one tag, the $activeTag, but all messages would get returned.
For your purpose CakepHP recommend using join function for filtering with HABTM, it joins hasOne or belongsTo for you automatically but when it comes to HABTM you may need to perform the join yourself if needed.
assuming tables are named conventionally:
$this->Message->recursive = -1;
$options['joins'] = array(
array('table' => 'messages_tags',
'alias' => 'MessageTag',
'type' => 'INNER',
'conditions' => array(
'Message.id = MessageTag.message_id',
)
) );
$options['conditions'] = array(
'MessageTag.tag_id' => $activetag['Tag']['id'],
'Message.user_id' => $this->uid );
$message = $this->Message->find('all', $options);
more info here:
http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html#joining-tables
In your Model Message add
**
* #see Model::$actsAs
*/
public $actsAs = array(
'Containable',
);
/**
* #see Model::$belongsTo
*/
public $belongsTo = array(
'Message' => array(
'className' => 'Message',
'foreignKey' => 'message_id',
),
'Tags' => array(
'className' => 'Tag',
'foreignKey' => 'tag_id',
),
);
in your controller :
// $tagsId = tags ids
$message = $this->MessageTag->find('all', array('conditions' => array('MessageTag.tag_id' => $tagsId),'contain' => array('Message')));
also is better follow cake naming convention, if you have tags(plural), message_tags(first singular second plural),messages(plural) tables you must have Tag,MessageTag,Message Models.
I am in the FilesController and I'm trying to get a file based on the condition that its order belongs to the current user.
FilesController
// Check the file exists and that it belongs to the user
$this->File->find('first', array(
'conditions' => array(
'File.id' => $id,
'Order.Customer.id' => $this->Auth->user('id')
),
'recursive' => 2
));
Cake SQL Error
Unknown column 'Order.Customer.id' in 'where clause'
I'm trying to get the SQL to left join orders onto files and then left join customers onto orders, but I can't figure out how to join the customers table, although I'm sure I've done this before. I've tried everything I can think of with the conditions, and using contains.
Here's my model relationships:
Customer Model
class Customer extends AppModel {
public $hasMany = array('Order');
}
Order Model
class Order extends AppModel {
public $belongsTo = array('Customer');
public $hasMany = array('File');
}
File Model
class File extends AppModel {
public $belongsTo = array('Order');
}
Try joining the tables using the 'joins' parameter. Sometimes 'contains' doesn't work and you need to fall back on this.
$this->File->find('first', array(
'conditions' => array(
'File.id' => $id,
'Order.Customer_id' => $this->Auth->user('id')
),
'joins' => array(
array(
'table' => 'orders',
'alias' => 'Order',
'type' => 'LEFT',
'conditions' => array('File.orders_id = Order.id')
),
array(
'table' => 'customers',
'alias' => 'Customer',
'type' => 'LEFT',
'conditions' => array('Customer.orders_id = Order.id')
)
)
));
You may want to use Containable (http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html) as it is the easiest solution. You can not use Order.Customer.id as Cake does not nest conditions like that. Manual joins would also work.
$this->loadModel('Customer');
$customer = $this->Customer->findById($this->Auth->user('id'), array(
'conditions' => array(
'File.id' => $id
),
'recursive' => 2
));
Orders will be accessible as:
pr($customer['Order']);
File will be accessible as:
pr($customer['File']);
I realised there is no need to actually join the customers table in this instance, because the orders table already has the customer_id.
$this->File->find('first', array(
'conditions' => array(
'File.id' => $id,
'Order.customer_id' => $this->Auth->user('id')
)
));
I'm trying to use on the fly associations to trim down the data I retrieve, but the model I'm using is associated to other models with a re-named field because I have 2 of the same models associated with it.
So, here's the model, say 'test', that has two 'user' fields, both related to the User model.
In the model:
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
),
'User_Watched' => array(
'className' => 'User',
'foreignKey' => 'user_id_watched'
)
);
When I retrieve data related to 'test', I want to only retrieve particular data linked to the 'User' and 'User_Watched' fields without any other nested information.
But when I do:
$this->User->unbindModel(array('hasMany' => array('something1', 'something2')), false);
then something1 and something2 data does not show up for the 'User' field of model 'test', but is still retrieved for the 'User_watched' field.
Can I not retrieve unwanted data for the 'User_watched' field?
Hope this makes sense... :)
KcYxA,
Containable behavior might help a lot in this case, as benjamin mentioned, your "find" queries would look like:
$this->User->find('first', array(
'conditions' => array('User.id' => $id),
'contain' => array('UserWatched')
));
In this case, you won't have to use unbindModel method. In this example, you'll get User and UserWatched data.
If you need only User data from "find", then tell Cake to "$this->User->contain();" so it won't go further then User model.
to use on the fly associations to trim
down the data I retrieve
Good idea.
'foreignKey' => 'user_id_watched'
should possibly be:
'foreignKey' => 'user_watched_id'.
Edit 1: At least this would make sense according to my current understanding. If user_id is a correct foreign key(FK), which cakephp uses to unbind the relations, but user_id_watched isn't, than your described behavior is explained.
Edit 2: The Containable behavior gives you another tool for controlling associated models.
Change $primaryKey in fly, run controller
Sample:
// Models
//....
class PreProductoDescripcion extends AppModel {
/**
* Primary key field
*
* #var string
*/
public $primaryKey = 'id_producto_descripcion';
//....
//....
}
class SenasaPedidosDetalles extends AppModel {
/**
* Display field
*
* #var string
*/
public $displayField = 'cod_tango';
public $belongsTo = array(
'SenasaPedidos' => array(
'className' => 'SenasaPedidos',
'foreignKey' => 'senasa_pedidos_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'PreProductoDescripcion' => array(
'className' => 'PreProductoDescripcion',
'foreignKey' => 'cod_tango',
//'conditions' => array('SenasaPedidosDetalles.cod_tango' => 'PreProductoDescripcion.codigo'),
'fields' => '',
'order' => ''
)
);
//....
#
// Controller Fly
//...
$this->SenasaPedidos->Behaviors->load('Containable');
$this->SenasaPedidos->SenasaPedidosDetalles->PreProductoDescripcion->primaryKey = 'codigo';
$datos = $this->SenasaPedidos->find(
