Script dies when trying to use $model->save() - php

Question

I am trying to use $model->save() .. but i can't get the error messages like the documentation instead the error message appears with trace error then the script dies.
for example i am trying to use this code:
$user = new Users();
$user->name = "Name";
if(!$user->save()){
//do stuff if there is an error
}
the problem is that i always get the validation error like this and the script dies and never returns false to enter the if condition :
password is required
#0 ..../UsersController.php(106): Phalcon\Mvc\Model->save()
#1 [internal function]: ....\UsersController->createAction()
#2 [internal function]: Phalcon\Dispatcher->callActionMethod(Object(....\UsersController), 'createAction', Array)
#3 [internal function]: Phalcon\Dispatcher->_dispatch()
#4 [internal function]: Phalcon\Dispatcher->dispatch()
#5 ....\public\index.php(41): Phalcon\Mvc\Application->handle()
#6 {main}**

Answer 1

I Finally found the solution, I found that somewhere in the services.php
this line was enabled and that what caused the exception to be thrown
Phalcon\Mvc\Model::setup(['exceptionOnFailedSave' => true] and after turning it to false,i can easily add my conditions and check the errors message using this code.
if ($model->save() === false) {
$messages = $model->getMessages();
foreach ($messages as $message) {
echo $message, "\n";
}
}

you can send flash error using
$this->flash->error("too bad! the form had errors");
$this->flash->success("yes!, everything went very smoothly");
$this->flash->notice("this a very important information");
$this->flash->warning("best check yo self, you're not looking too good.");
