php - Symfony 1.4 preUpdate method never firing

Question

I've got the following model class:

class ContractDetails extends BaseContractDetails {

    public function updateContractDetailsByConId($conId, $key, $value) {
        $q = Doctrine_Query::create()
              ->update('ContractDetails');
        if ($value === null) {
            $q->set($key, 'NULL');
        } else {
            $q->set($key, '?', $value);
        }

        $q->where('cd_con_id = ?', $conId)
                ->execute();

        return $q;
    }
    public function preUpdate($values) {
        $test = "test";
    }
 }

What I want is to run some code before the "updateContractDetailsByConId" method row is updated. From my investigations I should be able to use the built in hooks i.e. preUpdate But the preUpdate method is never running.

Any ideas why not?

当您从 DQL 查询更新时，您需要挂钩到 DQL 回调。有关更多信息，请参阅此处的文档。

在您的代码中，您需要更新preUpdatefor

public function preDqlUpdate($values) {
   $test = "test";
}

不要忘记，如文档中所述，您需要隐式打开 DQL 回调。在您的 ProjectConfiguration.class.php 文件中，添加：

public function configureDoctrine(Doctrine_Manager $manager)
{
   $manager->setAttribute(Doctrine::ATTR_USE_DQL_CALLBACKS, true);
}
