Hi,
i was looking around in the docs, and even though it seems there would
be a clean way to do this, i couldn''t find it.
i was hoping to take an array of objects, and create a new array of
objects, with different id''s.
like:
user_list = [user1, user2, user3, user4, user5]
and then do something in the vicinity of:
new_user_list = user_list.collect {|user| User.create(user.attributes)}
so that the only differance between the user_list and the new_user_list
is the id of each user. for somewhat reason, this isn''t working, as
i''m
sure there is also a cleaner way to do this.
is there?
thanks ahead of time,
harp
