Rails validation presence of all attributes in a group or none

I am trying to validate the presence of banking data of a customer
( bank name, bank address, bank branch, …)

If one of these fields is not blank then all other fields should be
filled…
Is there a smart way to validate it … i.e validate presence of a
group of attributes …

thanks fyfb

in your model

validate :all_or_none_address_fields

def child_and_team_code_exists
address_fields = [address1, address2, address3, town, county,
postcode] # these are all the attributes of the model you want all or
none of
errors.add_to_base(“All of the address fields need a value if any
of them are entered”) if
address_fields.any? && !address_fields.all?
end
