Yii调试SQL的常用方法,yii调试sql
Yii调试SQL主要有以下方法:
一、系统自带调试:
首先index.php开启调试模式:
// remove the following lines when in production mode defined('YII_DEBUG') or define('YII_DEBUG',true); // specify how many levels of call stack should be shown in each log message defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3); //app use time //defined('YII_BEGIN_TIME') or define('YII_BEGIN_TIME',microtime(true));
main.php页面:
'errorHandler'=>array( // use 'site/error' action to display errors 'errorAction'=>'site/error', ), 'log'=>array( 'class'=>'CLogRouter', 'routes'=>array( array( 'class'=>'CFileLogRoute', 'levels'=>'error, warning', ), // 下面显示页面日志 array( 'class'=>'CWebLogRoute', 'levels'=>'trace', //级别为trace 'categories'=>'system.db.*' //只显示关于数据库信息,包括数据库连接,数据库执行语句 ), ), ),
YII_TRACE_LEVEL的数字越大,信息越清楚
二、使用调试工具调试:
yii-debug-toolbar把包解压后 放到extensions里边 然后在配置文件main.php中最后加上
'log'=>array( 'class'=>'CLogRouter', 'routes'=>array( array( 'class'=>'ext.yii-debug-toolbar.YiiDebugToolbarRoute', 'ipFilters'=>array('127.0.0.1','192.168.1.215'), ), ), ),
没有出现的话加上在'components'下的db里加上两个属性,
'enableProfiling'=>true, 'enableParamLogging'=>true,
然后如果有其他调试工具的插件的话,可能会出现冲突导致sql语句不出来,把那段代码注掉即可。
除了cactivedataprovider,你还可以使用CArrayDataProvider
我给你写个例子:
controller中:
$rawdata = Yii::app()->db->createCommand('select * from {{post}} where idqueryAll();
$data = new CArrayDataProvider($rawdata, array(
'id' => 'user',
'sort' => array(
'attributes' => array(
'id', 'title', 'content'
),
),
'pagination' => array(
'pageSize' => 10,
),
));
$this->render('gridview_array', array('dataProvider' => $data));
然后view中:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'somegrid',
'dataProvider'=>$dataProvider,
'columns'=>array(
'id',
'title',
'content',
),
));
这样就ok 了~
就是一个一个实验了, 看看哪个结果返回的是你要的。这种自解释的语言没有什么所谓的调试方法。一条命令就搞定的,你认为怎么算是调试呢
