Find where id is not in array of ids

问题:

To find id whose value is equal to the id of an array of ids:

$this->YourModel->find('all', array(
    'conditions' => array(
        "YourModel.id" => array(1, 2, 3, 4)
    )
));

How I can do the opposite, find elements where the ids are different than an array of ids?

回答1:

This should work:

$this->YourModel->find('all', array(
    'conditions' => array(
        "NOT" => array( "YourModel.id" => array(1, 2, 3, 4) )
    )
));
