Overriding validate directly isn't recommended. Try:

validate_on_create do |record|   record.errors.add("", "Either home email or work email need to be entered.") if record.home_email.blank? || record.work_email.blank? end

validates_presence_of :home_email, :work_email, :message => "Either home email or work email need to be entered."

That would trigger an error unless both are provided. I think Seth wants an error only if none are given.

validate_on_create do |record|   record.errors.add("", "Either home email or work email need to be entered.") if record.home_email.blank? || record.work_email.blank? end

Sorry change the "||" in the if statement to "&&"

validate_on_create do |record|   record.errors.add("Home or work email", "need to be entered.") if record.home_email.blank? && record.work_email.blank? end

should work then. Your original 'unless' expression was saying they both needed to be provided.
