当debug设置为0时，如何获得执行查询的列表？
我在AppController中有以下功能：
// log INSERT, UPDATE, DELETE queries
private function __logQueries(){
$db = &ConnectionManager::getDataSource('default');
$query_logs = $db->getLog();
if( isset($query_logs['log']) && !empty($query_logs['log']) ){
$this->loadModel('SqlLog');
foreach($query_logs['log'] as $log_q){
$query = $log_q['query'];
if( stristr($query, 'INSERT ') || stristr($query, 'UPDATE ') || stristr($query, 'DELETE ') ){
$q_data = array(
'query' => $query,
'page' => $this->Misc->getCurrentPageURL(), // get the current page
'referrer' => trim(env('HTTP_REFERER')) == '' ? '' : env('HTTP_REFERER'),
'ip' => env('REMOTE_ADDR'),
'browser' => env('HTTP_USER_AGENT'),
'user_id' => SessionComponent::check('Auth.User') ? SessionComponent::read('Auth.User.id') : 0,
'username' => SessionComponent::check('Auth.User') ? addslashes(SessionComponent::read('Auth.User.username')) : '',
);
$this->SqlLog->create();
$this->SqlLog->save($q_data);
}
}
} // end if query occured
}
public function beforeRedirect(){
$this->__logQueries();
}
public function afterFilter(){
$this->__logQueries();
}
当debug设置为2时，会记录insert，update和delete查询，但是当debug设置为0时如何记录这些查询？
答案 0 :(得分：0)
是否记录查询取决于DboSource::$fullDebug属性，它是在DboSource构造函数中设置的，默认情况下true是debug > 1 true }}
所以你要做的就是用debug覆盖这个属性的值，这样就可以确保在这一点上记录查询，无论App::uses('ConnectionManager', 'Model');
ConnectionManager::getDataSource('default')->fullDebug = true;
设置如何。
