Question

Im probably missing something painfully obvious here. Im trying to join multiple tables together in Cake, but Im only getting the fields from the first table. Consider the following code..

$joins = array();
$joins[] =  array(
            'table' => 'products', 
            'alias' => 'Product', 
            'type' => 'LEFT',
            'conditions' => array(
                'Device.id = Product.device_id'
            )
    );

$joins[] =  array(
            'table' => 'pricepoints', 
            'alias' => 'Pricepoints', 
            'type' => 'LEFT',
            'conditions' => array(
                'Pricepoints.product_id = Product.id'
            )
    ); 
$all_products = $this->Device->find('all', array("joins" => $joins); 

And this returns the following SQL

SELECT `Device`.`id`, `Device`.`manufacturer_id`, `Device`.`name`, `Device`.`type_id`, `Manufacturer`.`id`, `Manufacturer`.`name` FROM `devices` AS `Device` LEFT JOIN products AS `Product` ON (`Device`.`id` = `Product`.`device_id`) LEFT JOIN pricepoints AS `Pricepoints` ON (`Pricepoints`.`product_id` = `Product`.`id`) LEFT JOIN `manufacturers` AS `Manufacturer` ON (`Device`.`manufacturer_id` = `Manufacturer`.`id`) 

ie. it only returns the fields from the parent Model ie. Device. How do I get it to select ALL fields from the join? Im presuming its to do with the way I have my Model relationships set up, but I think I have these set up correctly.

Anyone any advice?

Answer 1

you can specify the fields in the find query:

$all_products = $this->Device->find('all', array("fields" => array('Device.*','Product.*','Pricepoints.*')
                                                 "joins" => $joins
); 

Hope this helps
