Yii：如何从另一个控制器动作中调用控制器动作？

问题描述：

When I delete a 'type' i set isActive = 0;

Every 'type' 'has many' 'causal'

So when disabling a type i want disable every causal

in type controller i'm trying this

$model = $this->loadModel($id);
$model->isActive = 0;

foreach ($model->causalsObj as $key => $causal ) {
   $causal = CausalController::delete($causal->id);
}

$model->save();

This doesn't work (PHP error during ajax call)

当我删除'type'时，我设置isActive = 0; p>

每个“类型”都有很多“因果关系” p>

因此，当禁用某种类型时，我希望禁用类型中的每一个因果 p>

strong>控制器我正在尝试这个 p>

$ model = $ this-＆gt; loadModel（$ id）; $ model-＆gt; isActive = 0; \ nforeach（$ model-＆gt; causalsObj as $ key =＆gt; $ causal）{ $ causal = CausalController :: delete（$ causal-＆gt; id）; } $ model-＆gt; save（）; code> pre> 这不起作用（在ajax调用期间出现PHP错误） p> div>

That should go into the model, not the controller, I'd use afterSave. so in the CasualType:

public function afterSave(){
   if(!$this->isActive){
       Casual::model()->deleteAll('type_id = '.$this->id);
   }

   return parent::afterSave();
}

If you don't actually mean 'delete' but deactivate you can still do this in one single query using CActiveRecord::updateAll:

public function afterSave(){
   if(!$this->isActive){
       Casual::model()->updateAll(array('isActive' => 0), 'type_id = '.$this->id);
   }

   return parent::afterSave();
}

Instantiating a controller in another controller does not make sense, controllers are there to handle user requests, not to hold your business logic

答

Looks like the problem is in your foreach loop, if you already have a relation set up you should be able to access it with $model->causal. If that doesn't work, check your relations are working correctly

$model = $this->loadModel($id);
$model->isActive = 0;
foreach ($model->causal as $item){
   $item->delete();
}
$model->save();

答

Do you have the following at the top of your code?

Yii::import('application.models.CausalController');

This should make it possible.

Also using SuVeRa's way to delete the items would be nicer:

foreach ($model->causalsObj as $key => $causal ) {
   $causal->delete(); 
}

Or you can create a function in CausalController which deletes all causal's for a given id.
