Hi,
thanks
but I have instance like this
@restaurant= Restaurant.find(:all)
now for each i have to add one more column
@restaurant.each_with_index do |c,index|
@restaurant[index]['diffinmiles'] =22
end
but this is not work
so that i have to not change in view file and i can direct access like
db values ?
any idea ?
