With CakePHP, How to select records based on conditions on related tables
Another noob question - using v1.2.1.8004 of CakePHP, I think...
I have 3 tables, broker (B), quote_site (QS) and broker_quo开发者_C百科te_site (BQS) that links them together.
B has many BQS (it belongs to B) QS has many BQS (it belongs to QS)
I am trying to retrieve quote sites, that are linked to a specific broker, but CakePHP is not doing the joins to the tables behind the scenes.
Here is my query:
$quote_sites = $this->QuoteSite->find('all', array(
'conditions' => array(
'Broker.company_id' => $company_id,
'BrokerQuoteSite.is_active' => true
),
'contain' => array(
'BrokerQuoteSite' => array(
'Broker'
)
)
));
Here are the related models:
<?php
class QuoteSite extends AppModel
{
var $name = 'QuoteSite';
//$validate set in __construct for multi-language support
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $hasMany = array(
'BrokerQuoteSite' => array(
'className' => 'BrokerQuoteSite',
'foreignKey' => 'quote_site_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
?>
Broker:
<?php
class Broker extends AppModel
{
var $name = 'Broker';
//$validate set in __construct for multi-language support
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $hasMany = array(
'BrokerQuoteSite' => array(
'className' => 'BrokerQuoteSite',
'foreignKey' => 'broker_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
?>
And the last one:
<?php
class BrokerQuoteSite extends AppModel
{
var $name = 'BrokerQuoteSite';
//$validate set in __construct for multi-language support
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
'Broker' => array(
'className' => 'Broker',
'foreignKey' => 'broker_id',
'conditions' => '',
'fields' => '',
'order' => '',
) ,
'QuoteSite' => array(
'className' => 'QuoteSite',
'foreignKey' => 'quote_site_id',
'conditions' => '',
'fields' => '',
'order' => '',
)
);
}
?>
Thanks in advance for any tips/tricks.
Chris why don't you define Broker as a HABTM relationship then a simple find will retrive the desired results?
class Broker extends AppModel {
var $name = 'Broker';
var $hasAndBelongsToMany = array(
'QuoteSite' =>
array(
'className' => 'QuoteSite',
'joinTable' => 'broker_quote_sites',
'foreignKey' => 'broker_id',
'associationForeignKey' => 'quote_site_id'
)
);
}

Nice question and what I thought is to make it two steps
$this->Broke = ClassRegistry::init("Broke");
$brokeids = $this->Broke->find("list",array("conditions"=>array('Broker.company_id' => $company_id))); //get all B ids
$this->QuoteSite->Behaviors->attach('Containable'); //use containable behavior
$quote_sites = $this->QuoteSite->find('all',array(
'contain'=>array(
'BrokerQuoteSite'=>array(
'conditions'=>array(
"BrokerQuoteSite.broke_id"=>$brokeids,
"BrokerQuoteSite.is_active" => true
)
)
)
)
);
The code is NOT tested yet,maybe some syntax mistakes out there.Hope it helps.
update
$this->Broke = ClassRegistry::init("Broke");
$this->Broke->recursive=2;
$brokes = $this->Broke->find("all",array("conditions"=>array("Broke.company_id"=>$comany_id)));
the QS information you need shall be found if you view the result with debug($brokes);
.What you need to do is extracting them from the array.
Cheers.
