Change action in Yii system
I am working on a web application that allows users to video conferencing. Users are allowed to create video conferencing and I want them to be able to edit scheduled video conferencing too, but I am having problems with that. Please, help.
Edit button in index.php view
$html .= CHtml::ajaxLink('Edit',
Yii::app()->createAbsoluteUrl('videoConference/update/'.$vc->id),
array(
'type'=>'post',
'data' => array('id' =>$vc->id,'type'=>'update'),
),
array( "visible" => $ismoderator, 'role' => "button", "class" => "btn btn-info")
);
Video Conferencing Controller Action Update
/**
* Updates a particular model.
* If update is successful, the browser will be redirected to the 'view' page.
* @param integer $id the ID of the model to be updated
*/
public function actionUpdate($id)
{
$model = $this->loadModel($id);
if (isset($_POST['VideoConference'])) {
$model->attributes = $_POST['VideoConference'];
if ($model->save())
$this->redirect(array('view', 'id' => $model->id));
}
$this->render('edit', array(
'model' => $model,
));
}

After a little troubleshooting, I finally got it to work. In the view, I call the actionUpdate method like this:
$html .= CHtml::button('Edit', array('submit' => array('videoConference/update/'.$vc->id), "visible" => $ismoderator, 'role' => "button", "class" => "btn btn-info"));
On the controller just changed
$model->save() to $model->update()
and it works great.

The first step is to find where the problem is (frontend / backend). You need to call the action without ajax (only with url with param id). Try my version:
/**
* Updates a particular model.
* If update is successful, the browser will be redirected to the 'view' page.
* @param integer $id the ID of the model to be updated
*/
public function actionUpdate($id)
{
$model = $this->loadModel($id);
if ($model == null) {
throw new CHttpException(404, 'Model not exist.');
}
//if (isset($_POST['VideoConference'])) {
//$model->attributes = $_POST['VideoConference'];
$model->attributes = array('your_attr' => 'val', /* etc... */);
// or try to set 1 attribute $model->yourAttr = 'test';
if ($model->validate()) {
$model->update(); //better use update(), not save() for updating.
$this->redirect(array('view', 'id' => $model->id));
} else {
//check errors of validation
var_dump($model->getErrors());
die();
}
//}
$this->render('edit', array(
'model' => $model,
));
}
If everything works fine on the server side (line is updated), check the query parameters, console, tokens, etc. The problem will be in the interface.
