Hi Nanyang,
 u r correct, my mistake....model name is FoodDept but the string i want to
pass is "food_dept". The reason is that there are different dept under a
model Dept and FoodDept is an inherited model from it.. now for my app, i
need to send different dept to a method for processing and hence i was
trying to send  the string name.
