Question

I’d like to increment the value of a column in cakePHP.
Is there a way to have cakePHP write this?

UPDATE `gigs` SET `visits` = visits+1 WHERE `gigs`.`id` = 1

I tried this:

function addVisit($id){
    $this->id = $id;
    $this->saveField('visits', 'visits+1');
}

but cakePHP adds quotes around visits+1.

UPDATE `gigs` SET `visits` = 'visits+1' WHERE `gigs`.`id` = 1

I tried double quotes, results the same.

Answer 1

$this->updateAll(array(), array('Model.field + 1'))

or

$this->updateAll(null, array('Model.field + 1'))

one of them should work, saveField does not allow sql fragments, updateAll does
