Urgent + Validations

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.

The :if options to the various validations allows you to specify your own logic as to which validations should run given the state of the object.

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.
