ensure $model->link worked in debug mode?

Yii 2.0 General Discussions

Hi Guys!

I understand that the errorHandler will catch errors like the below one with disabled debug mode…

But when you are in development environment with debug enabled,

how to ensure that - for example - $model->link() worked??

Lets say for example you have following code:




// $master is empty by purpose in this example 

// because I want to generate an error for understanding my question

$master = new Master; 


$slave = new Slave;


// some code to fill all attributes for slave except FK for example:

$slave->attributes = Yii::$app->request->post('Slave'); 


// now I link slave to master with 

$slave->link('master', $master);

But how can I verify / catch excpection?

That it was successfully linked when in debug mode?

And how can I react when it was not linked?

For example I want something like:




if($slave->link('master', $master)){

  Yii::$app->session->setFlash('success','This slave has now a master! YEEY!');

}

else{

  Yii::$app->session->setFlash('error', 'This slave could not be saved.');

}


// redirect or whatever

Since “link” does not return true / false I can’t use IF.

And try - catch block only works with general php exception like:




try{

  $slave->link('master', $master); 

  Yii::$app->session->setFlash('success','This slave has now a master! YEEY!');

}

catch(\Exception $e){

  Yii::$app->session->setFlash('error', "$e");

}


// more code

But if I use "general exception" the errorHandler will not lead to site/error when debug is disabled.

What is the best way?

How you guys are doing this?

Best Regards
