Hello, 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. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hello Fred,
Thanks for a quickie. But did''nt quite get it. Is it something like
this?
validates_presence_of :abc_column, :on => :update, :if => some_method ..
and then this method should be defined somewhere.
def some_method
if particular_param_is_present
return true
end
return false
end
Fred, am i doing correct here.
I have tried it this way, but this validation is still coming in all
pages. I mean other pages also where i am updating.
