validate mac address field

Hi to all,

i'd like to insert a validation inside my model about a mac address field. I've used this sintax but it's not working.

validates_format_of :mac_address, :with => /^((?:[-a-f0-9])+(?:[-a-f0-9])+(?:[-a-f0-9])+(?:[-a-f0-9])+(?:[-a-f0-9])+(?:[-a-f0-9]))$/i,                                           :on => :create,                                           :on => :update,                                           :message => "MAC ADDRESS incorrect"

this code it's not working, i'm looking for a solution but i can't find out the problem...

Any help will be great...

Thanks

Andre

Try with this regexp:

/^([0-9a-fA-F]{2}[:-]){5}[0-9a-fA-F]{2}$/i

irb(main):001:0> '00:09:6B:DF:FE:42' =~ /^([0-9a-fA-F]{2}[:-]){5}[0-9a-fA-F]{2}$/i => 0
