Answer 1

Try using contain like this:
$webPayments = $this->Website->find('all', array(
'fields' => array(
'Website.id',
),
'contain' => array(
'Payment' => array(
'fields' => array(
'Payment.id',
'Payment.website_id',
'Payment.created',
'Payment.user_id'
),
'conditions' => array(
'Payment.website_id <>' => '0',
'Payment.is_get_invoice' => '0'
),
'order' => array(
'Payment.id DESC',
'group' => array(
'Payment.website_id'
)
)
)
)
));

Answer 2

Are your models declared properly for the association? You should have
class Payment extends AppModel {
var $name = 'Payment';
public $actAs = array('Containable');
public $belongsTo = array (
'Website' => array(
'className' => 'Website',
'foreignKey' => 'website_id'
)
)
[...]
}
class Website extends AppModel {
var $name 'Website';
public $actAs = array('Containable');
public $hasMany = array(
'Payment' => array(
'className'=>'Payment',
'order' => 'Payment.id DESC'
)
)
[...]
}
I find that declaring things as low as possible in the model really works better than trying to do it on the fly with a query.. If the association is properly declared in the model itself you shouldn't have to dork with binding/unbinding like that..

Answer 3

The hasMany association does not support the group by key.
In this particular case, what you are trying to achieve by the incorrect use of group is to return just one result. Note that the same functionality can be accomplished by using the limit key, which is supported.
The code would be the following:
$this->Website->unBindModel(array('hasMany' => array('User')));
$this->Website->bindModel(array(
'hasMany' => array(
'Payment' => array(
'className' => 'Payment',
'foreignKey' => 'website_id',
'fields' => array(
'Payment.id',
'Payment.website_id',
'Payment.created',
'Payment.user_id',
'Payment.is_get_invoice'
) ,
'conditions' => array(
'Payment.website_id <>' => '0',
'Payment.is_get_invoice' => '0'
),
'order' => array(
'Payment.id DESC'
),
'limit' => 1
)
)
)
)
);
