I have 3 models Product having product_family_id as foreign key to ProductFamily and ProductFamily have customer_id as foreign key to Customer. Putting recursive to 2 in Product model allow me to get Customer name from Customer for a product. But its too slow as data is vast

Tried Using Bind model as below. Didn't worked for me. Using Cakephp framework.

$this->Product->bindModel(array(
'belongsTo' => array(
               'ProductFamily' => array(
                   'foreignKey' => false,
                   'conditions' => 
                        array('Product.product_family_id = ProductFamily.id')
                   ),
               'Customer' => array(
                   'foreignKey' => false,
                   'conditions' => 
                        array('ProductFamily.customer_id = Customer.id')
                   )
               )
           )); 

Answer 1

Use Containable

The Containable behaviour will help you get exactly the data you want without the overhead of recursive 2

set it in your AppModel to make it apply to all models at once and read up on the docs on how to use it

class AppModel extends Model {

    public $actsAs = array('Containable');
    public $recursive = -1;
}

For some interfaces in your application, you may not need that much information from the model. One thing the ContainableBehavior does is help you cut down on what find() returns.

It is possbible to only set this on the models where you would use it and set recursive to -1 right before your find (in wich you would use 'contain') but it is in my eyes a best practise to do this for all models

Answer 2

Like Alex mentioned in his response, you can use the containable behavior. His idea is to use the Containable behavior for the whole AppModel, i.e it affects all the Models. And if you have already used recursions at other places of the code, you will have to adjust the models to contain in each part of them.

But if you only want to limit data for this model. You can do

$this->Product->Behaviors->attach('Containable');
$this->Product->contain(array(
    'ProductFamily' => array('Fields you need from product family'), 
    'Customer' => array('Fields from customer')
);

If you need all fields from ProductFamily and Customer, you can do

$this->Product->contain(array('ProductFamily', 'Customer'));
