Update two models with one view not working in Yii? - php

Question

Can anybody help me resolve my issue? I'm able to do create new records but I can't modify or update my existing records.
Here is my source code:
public function actionCreate() {
$model = new Branchmaster;
$user = new Usermaster;
if(isset($_POST['Branchmaster'], $_POST['Usermaster'])) {
$model->attributes=$_POST['Branchmaster'];
$user->attributes=$_POST['Usermaster'];
$valid=$model->validate();
$valid=$user->validate() && $valid;
if($valid){
$model->save();
$chnuser->save();
$this->redirect(array('view','id'=>$model->Id));
}
}
$this->render('create',array(
'model'=>$model,
'user'=>$user,
));
}
public function actionUpdate($id) {
$model=$this->loadModel($id);
$user = Usermaster::model()->findByAttributes(array('branch_id'=>$model->Id));
if(isset($_POST['Branchmaster'], $_POST['Usermaster'])) {
$model->attributes=$_POST['Branchmaster'];
$user->attributes=$_POST['Usermaster'];
$valid=$model->validate();
$valid=$user->validate() && $valid;
if($valid){
$model->save();
$user->save();
$this->redirect(array('view','id'=>$model->Id));
}
}
$this->render('update',array(
'model'=>$model,
'user'=>$user,
));
}
I need help for this problem... Thanks in advance!

Answer 1

You have to check if id is exited than u have to do update...
use findByPk to load model...
than do process to same is above
here is sample code. you have to implement like these
$model->attributes=$_POST['Branchmaster'];
$user_post = $_POST['Usermaster'];
$id = $user_post['id'];
$user = ModelName::model()->findByPk($id);
$user->variable_name = $variable_value
$valid=$model->validate();
$valid=$user->validate() && $valid;
if($valid){
$model->save();
$user->save();
$this->redirect(array('view','id'=>$model->Id));
}
Thanks

Instead of find 'findByAttr' so that will be
// pls note tht $id must be a primary key of this particular model
$user = Usermaster::model()->findByPk($id);
// If the situation don't allow a primary key then we can go for query execution
$update = Yii::app()->db->createCommand()
->update('usermaster', array('field1'=>'value','field2'=>'value2'),
'branch_id=:id',array(':id'=>$branch_id));
