i have three models A,B,C. A belongs to B,B belongs to C.How to get C’s attribute in A’s gridview?

in the item list:


array(

   'label'=>'Attribute of C',

   'value'=>'$item->B0->C0->attributeName'

)

This works if you have the relation B0 in A and C0 in B that returns the B and C models respectively.
