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?

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.
