Subject: Finding an element in an array of hashes

Hi,

I have an array of Facebooker::User objects

so friends.class = Array
and friends[1].class = Facebooker::User

Facebooker::User objects which are basically hashes.

each friend has a unique facebook_id so
friends[1].facebook.id.class = Integer

I'd like to find the array member with a particular facebook_id.

friends.find_by_id(12345) should return the corresponding
Facebooker::User object

What's the cleanest way to do this?
Do I have to iterate over the array members or is there a method in Ruby
that does this?

Thanks

Alex
