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. :slight_smile:

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. :slight_smile:
