Hello, I have problem with custom validator which should check such situation: I have two fields text_field ''object'', ''others'' and text_field ''object'', ''others_area'' I "raise" error if others is nil but others_area is filled up also when others is not nil but others_area isn''t numeric If both fields are nil it''s ok i allow such situation. How can I do that in one correlated validator?

Use custom validation in your model of ''object''. Use something like this: class Bla < ActiveRecord::Base def validate if others.nil? and others_area.not_numeric? then errors.add("nasty thing", "happenned") end end end --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

you need to write your own validation with validates_each
something like:
validates_each :others, :others_area, :on => :create, do |record, attr,
value|
unless others then #check for nil
... # do your validation here
# and add error to record if necessary:
record.errors.add :others, ''your message''
end
end
end

Is it possible to embed one validator into another?
