Validating numericality based on related attribute value?
I have a price attribute in my model which I need to validate as a
positive number if the attribute price_terms.requires_value is equal to
''Y'', otherwise price can be blank or zero. Price_terms is a select list
which my model table belongs_to.
How do I do this? - I tried doing this:
validates_numericality_of :price, :if =>
self.price_term.requires_value.upcase == ''Y''...
