I am saving/updating same object on different pages with some
validations. On first page, I save my object and on 2nd, 3rd, 4th pages
i update the same object. So at first page i am using
validates_inclusion_of :in =>  etc, and in second page(updating), i am
using validates_presence_of :abc, :on => [:update]. But while i update
on 3rd page also, i need some validations but i can not find out which
function should i use.
If i use validates_presence_of .. then this validations is reflecting on
save page, And if i use validates_presence_of :on => [:update] then that
is reflecting on update page. so i am in a bit of dilemma that what
should i use.
Thanks in advance.
