Are you trying to use uuid values? If not then there should be no
need for anything. Post the full error and trace if you do not think
you are using uuid values. First though search your source code for
‘uuid’.

If you are using uuid values show us the code that uses it and tell us
which version of rails you are using.

There is no native support for uuid in rails as far as I know. I
believe there are gems available to provide this, though I have not
used them, google should help you find them. If you picked up this
code from an example or tutorial have a look at it and see if it makes
a recommendation.

Do you really need uuids though?

By the way, if you need to use rails 2.3 you should at least use the
latest 2.3.x (11 I think) as there were some security fixes. If you
are writing a new app then best to use 3.1

On Rails 3 you could use:

in Gemfile:

gem ‘uuidtools’

in the code:

UUIDTools::UUID.random_create.to_s

I am not sure how well this would work in Rails 2.3.x

HTH,

If you don’t really need a real uuid, you could just gen something
similar yourself using ActiveSupport::SecureRandom.hex:

…
def gen_uuid_ish
s = ActiveSupport::SecureRandom.hex(16)
[ s[0…7], s[8…11], s[12…15], s[16…19], s[20…-1] ].join(’-’)
end
…

which will produce strings like “3ec1a6a0-017a-8fb4-0c26-56858ddc3886”
