Can I use validates_presence_of somehow if I want to check that at least one of 2 fields is not empty?

I''m still new to Rails, but I think you need to add a
''validate'' method
to your controller and perform the check in there instead.
Off the top of my head, something like:
protected
def validate
errors.add("Either tweedledum or tweedledee need to be entered.")
unless tweedledum != nil or tweedledee != nil
end
I can''t see a way of using validates_presence_of for this.
Regards,
Chris.

And is it possible to embed this ''validate'' method into the model; say, into the before_save filter or something like that? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I think Chris meant to tell you to add the validate method to the model. This will then be called in the normal validation routine.

Hi ! 2006/9/7, Max Muermann <ruby@muermann.org>:> If you have a method called "validate" on your model, this is used > automatically by the valid? method. No need to do anything else.The only problem with that is if you have subclasses that override the validate method. Unless the subclass calls the superclass method, your validations won't work as expected. class Order < AR::Base def validate # this will never be called end end class RushOrder < Order def validate self.errors.add(:status, 'invalid') if self.status.blank? end end If you do this instead: class Order < AR::Base before_validation :check_base_order def check_base_order # this will always be called end end class RushOrder < Order before_validation :check_rush_order def check_rush_order # this will ALSO always be called end end Hope that helps ! -- François Beausoleil http://blog.teksol.info/ http://piston.rubyforge.org/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Yes, I meant model, but wrote controller. Also it should be @tweedledum etc. The ''unless'' is a continuation of the ''errors.add'' line, but it''s come out with bad formatting.
