i have 2 models, Group and User related by MANY-MANY
in Group.php ‘members’ => array(self::MANY_MANY, ‘User’, ‘int_user_group(group_id,user_id)’),
in update action of groupcontroller, code generated by CRUD have $this->render(‘update’,array( ‘model’=>$model,
and $model is returned by loadModel($id), so in _form.php partial view how can i access related group model using $model?
I tried $model->members->findAll() but this gives fetal error Call to a member function findAll() on a non-object in /home/nib/lab/ssaconnect/protected/views/group/_form.php on line 48

Relational Active Record - Performing Relational Query
// Instead of loading only one Group model with loadModel() => load group model with related User models
$model = Group::model()-with('members')->findByPk($id);
$users= $model->members; // array of User models
You have to do manual the saving of the related user data or use an extension like cadvancedarbehavior.
But I think doing an update of the User with the related groups would be the way to go instead of updating groups.
Well i am agree with reply of kokomo.And regarding a updation of relation model in Yii.Still there is no inbuilt solution for that.Since i have already post a threadregarding it.
That is why you need to write down your own method into a model class and call it according to your appropriate business logic.
