Sure -- just write the method :-) I would consider putting the blanks
in a constant.
class Whatever
BLANKS = [0, "0", "", " "]
def self.normalize_fields(*syms)
syms.each do |attr|
define_method("#{attr}=") do |value|
write_attribute(attr, BLANKS.include?(value) ? nil : value)
end
end
end
normalize_fields :address, :city, :country_id
end
