How about this ?
validate do |applicant|
errors.add_to_base("Things must check out!") unless applicant.check_things
end
def before_save
applicant.non_represented_field = 123456789
end
before_save will only be called if your validations pass, so
non_represented_field will only be assigned to valid records.
