\yii\db\ActiveRecord
我已经用我自己的班级覆盖了现有的。我覆盖的方法是beforeSave()
. 我已阅读有关用法的文档。但是我发现它在检查记录是否是新记录时被调用了两次。
这是我的代码:
class ActiveRecord extends \yii\db\ActiveRecord{
public $count = 0;
public function beforeSave($insert) {
print($this->count++); //i try to investigate it deeper using this "count" property
if(parent::beforeSave($insert)){
if($this->isNewRecord){
print("123"); //this printed out
if($this->hasAttribute('user_create')){
$this->user_create = \Yii::$app->user->identity->id;
}
if($this->hasAttribute('time_create')){
$this->time_create = new \yii\db\Expression('now()');
}
}
else{
print("456"); //and this is also
if($this->hasAttribute('user_upd')){
$this->user_upd = \Yii::$app->user->identity->id;
}
if($this->hasAttribute('time_upd')){
$this->time_upd = new \yii\db\Expression('now()');
}
}
return true;
}else{
return false;
}
}
}
当我保存新记录时的代码输出如下
01231456
