Answer 1

In indexaction function, change the dataprovider code as below.

$dataProvider = new CActiveDataProvider('User','criteria'=>array(
   'with'=>array(
       'address'
    ),
    'together'=>true,
));

You can get the data from address table using $data->address->address_table_field_name in your view file.

Here address is relation name defined in your user model file.

Answer 2

try using

$model= User::model()->with('address')->findAll();

Note:- address in with('address') is the relation Name.

Eg:- To get User records try this

foreach($model as $record)
{
echo $record->id . $record->name;
}

To get address records try this

foreach($model as $record)
    {
    foreach($record->address as $myaddress)
{
echo $myaddress->id . $myaddress->userId . $myaddress->address;
}
    }

Answer 3

You don't need to use CActiveDataProvider, rather use the model directly.

Give it a try

foreach( User::model()->findAll() as $user ) {
   $address = $user->address;
   foreach( $address as $a ) {

   }
}
