Validating and saving a MAC address using only one format

Hi people,

I''m developing my first rails app, and I''m having a little
issue with
model validations:

=require_gem ''netaddr''

(...) (AR model definition)

protected
	def validate
		@eui = NetAddr::EUI.create(mac).address(:Delimiter=>'':'')
		#@eui.address(:Delimiter=> ''.'')
		rescue NetAddr::ValidationError
			errors.add(mac, "Incorrect MAC address format")
	end
=
My idea is to ensure at the model level, that a MAC address is
properly filtered and saved using the following format:

0000.1111.2222

... and automatically convert the following netaddr-supported formats
to the above one:

00:00:11:11:22:22
00-00-11-11-22-22
(...)

Now when I try to add a MAC using any format, it saves
''000011112222''
on the DB and I cannot figure why it''s happening by looking at netaddr
code.

NetAddr uses gsub!(/[\.\:\-]/, '''') all around to remove
formating
chars, but ".address(:Delimiter =>''.'') " should
put ''.''-format back to
the MAC string, shouldn''t it ?

Thanks in advance.

Re: Validating and saving a MAC address using only one format

When tried standalone (outside rails), it works like a charm :_/ What
i''m doing wrong with exception management ?

irb(main):001:0> require_gem ''netaddr''
=> true
irb(main):002:0>
NetAddr::EUI.create(''00:00:11:11:22:22'').address(:Delimiter=>''.'')
=> "0000.1111.2222"
irb(main):003:0>
NetAddr::EUI.create(''00:00:11:11:22:22'').address(:Delimiter=>''-'')
=> "00-00-11-11-22-22"
irb(main):004:0>
NetAddr::EUI.create(''00:00:11:11:22:22'').address(:Delimiter=>'':'')
=> "00:00:11:11:22:22"
irb(main):005:0>

Re: Validating and saving a MAC address using only one format

Also tried with ActiveRecord callbacks used in the model:

def after_validation
	self.mac =
NetAddr::EUI.create(mac).address(:Delimiter=>''.'')
	rescue NetAddr::ValidationError
		errors.add(mac,"Incorrect MAC address format")
end

But the ValidationError never raises :-/ Any bet ?

Thanks
