transaction error

My action create:

 public function actionCreate() {

      

        $model = new User('create');


        if (isset($_POST['User'])) {

            $model->attributes = $_POST['User'];

            

            $transaction = $model->dbConnection->beginTransaction();...

      

why the attributes are null and i get this error on beginTransaction

Fatal error: Call to a member function beginTransaction() on a non-object

If i change :

$model = new User('create'); 

to

$model = new User; 

i dont get the error.

I had to specify the (‘create’) for the rule:

array('pass','required','on'=>'create'),

to work

This is the way you should do your transactions:

if(isset($_POST['User']))

{

	$connection=Yii::app()->getDb();

	$transaction=$connection->beginTransaction();

	$model=new User('create');


	try

	{

		$model->attributes=$_POST['user'];

		if(!$model->save())

			throw new Exception(CHtml::errorSummary($model));

		$transaction->commit();

	}

	catch(Exception $e)

	{

		$transaction->rollBack();

		$error=$e->getMessage();

	}	

}

Thank you very much.One thing.what does this code?:

$error=$e->getMessage();

Take a look here http://php.net/manual/en/language.exceptions.php

Basically it catches the error thrown in the try{} portion of the code[throw new Exception(CHtml::errorSummary($model));]

yes i understand the catch of the exception. What i dont understand is where the $error variable is shown

Oh come on now

after the try/catch block you can check if(!empty($error)) and use the $error variable in the view to show the error to the user.

Smth along these lines:

//controller


public function actionSomething(){


$error=null;

if(isset($_POST['User']))

{

        $connection=Yii::app()->getDb();

        $transaction=$connection->beginTransaction();

        $model=new User('create');


        try

        {

                $model->attributes=$_POST['user'];

                if(!$model->save())

                        throw new Exception(CHtml::errorSummary($model));

                $transaction->commit();

        }

        catch(Exception $e)

        {

                $transaction->rollBack();

                $error=$e->getMessage();

        }       

}

$this->render('your-view',array('error'=>$error));

}




//view

<?php if(!empty($error)): echo $error; endif; ?>

ah ok.Thanks

Now i have this error on catch when validates:

Property "UserController.pass" is not defined.

public function actionCreate() {

       


        $model = new User('create');


        if (isset($_POST['User'])) {

            $connection = Yii::app()->getDb();

            $transaction = $connection->beginTransaction();

            


            try {

                $model->attributes = $_POST['User'];

                 $palavra = $model->pass;

                if ($model->validate()) {...<

You’re doing $this->pass instead of $model->pass somewhere in your controller code, that’s the problem.

yes that’s what i thought too but i cant find,here’s my entire action create:

 public function actionCreate() {

        Yii::import('ext.yii-mail.YiiMailMessage');


        $model=new User;


        if (isset($_POST['User'])) {

            $connection = Yii::app()->getDb();

            $transaction = $connection->beginTransaction();

            $model = new User('create');


            try {

                $model->attributes = $_POST['User'];

                 $palavra = $model->pass;

                if ($model->validate()) {

                    $model->save();

                    $message = new YiiMailMessage;




                    $message->setBody('<h1>StyleStore</h1>Efectuou o registo com sucesso no style store,já pode fazer login.<br><br>

                    Utilizador: ' . $model->username . '<br>Password: ' . $palavra . '<br><br>Obrigado pelo seu registo.<br><br>Cumprimentos.', 'text/html');

                    $message->setTo($model->email);

                    $message->subject = 'Registo de Utilizador';

                    $message->from = Yii::app()->params['adminEmail'];

                    Yii::app()->mail->send($message);

                    $message2 = new YiiMailMessage;

                    $message2->subject = 'Registo de Utilizador';

                    $message2->setBody('<h1>StyleStore</h1>Foi registado um novo utilizador com o nome ' . $model->nome, 'text/html');

                    $message2->setTo(Yii::app()->params['adminEmail']);

                    $message2->from = Yii::app()->params['adminEmail'];

                    Yii::app()->mail->send($message2);

                    Yii::app()->user->setFlash('success', Yii::t('app', 'Data saved! An email was sent to confirm the credentials'));

                    $transaction->commit();





                    if (Yii::app()->user->checkAccess('Admin'))

                        $this->redirect(array('view', 'id' => $model->iduser));

                    else

                        $this->redirect(Yii::app()->homeUrl);

                }

            } catch (Exception $e) {

                $transaction->rollBack();

                $error = $e->getMessage();

                Yii::app()->user->setFlash('error', Yii::t('app', $e->message));

                $this->redirect('create');

            }

        }


        $this->render('create', array(

            'model' => $model,

        ));

    }

what about the view ? have you checked there ?

Anyway, the yii debugger should highlight the error for you, so track the stack of messages and see where it dies.

Strange .I just get this if i use the netbeans-xdebug.If i run without debugging all gets fine.
