#dbkey(suffix = nil, _ignored = nil) ⇒ Object

+suffix+ is the value to be used at the end of the db key (e.g. customer:customer_id:scores would have scores as the suffix and customer_id would have been the identifier in that case).

identifier is the value that distinguishes this object from others. Whether this is a Horreum or DataType object, the value is taken from the identifier method).
