Rails - Mar 2007 - has_and_belongs_to_many -- has anyone made this easier yet?

Not that this isnt REALLY EASY already.. it is!!! I was just wondering if
someone had already waved their magic wand on this problem. :-)

I''ve got users and groups.. both has_and_belongs_to_many eachother. I
want
to be able to check for the users and groups by ID# or string to make the
coding easier. So in User, I have this:

  has_and_belongs_to_many :groups, :join_table => "users_groups" do
    def include?(group)
      if group.class == Fixnum
        group = Group.find group
      elsif group.class == String
        group = Group.find_by_name group
      end
      super
    end
  end

and in Group, I have this:

  has_and_belongs_to_many :users, :join_table => "users_groups" do
    def include?(user)
      if user.class == Fixnum
        user = User.find user
      elsif user.class == String
        user = User.find_by_name user
      end
      super
    end
  end  

... is there a way to do it better, more clearly, with less lines of code?

  Thanks,
    Tyler

Could you show some unit tests that reveal what this easier coding is 
supposed to look like?

Not a chance. What I was hoping to do was eliminate that "do" block
and have
some magic wand to replace it that recognizes that when I do something like:

user.groups << "Admin"

or

user.groups << 1

it will just do the right thing.

However, my pride and respect for ruby is brimming right now, so I will
share my modified acts_as_authenticated, which allows you to do:

require_group :Admin

(or any other group name) in a controller, and have login decisions based
upon that. :-)
