textfield with related model attribute

I want a textfield within my form to show a field of a related table.

I have tables as follows

tbl_family with field called family_name

tbl_people which is related via family_id to tbl_family

<?php echo $form->textField($model,'family_id',array('size'=>60,'maxlength'=>100, 'disabled'=>true,'style'=>'width: 130px;')); ?>

the code above will display the family_id of the People model in the box. How do I get it to display the family_name instead of family_id?


If I presume family as relational attribute of people

I hope we can achieve it by the following way.

<?php echo $form->textField($model,'family_id',array('value'=>$model->family->family_name)); ?>
