如何在cakephp 2中获取字段的枚举值

how to get enum values of a field in cakephp 2

In 1.3 i could have got it easily with _schema array

// get column type
$type = $this->Model->getColumnType('field');

// extract values in single quotes separated by comma
preg_match_all("/'(.*?)'/", $type, $enums);

// enums
var_dump($enums[1]);
