Hi

In the classic hasmanythrough example:

class Group < ActiveRecord::Base
        has_many :memberships
        has_many :users, :through => :memberships
end

class User < ActiveRecord::Base
        has_many :memberships
        has_many :groups, :through => :memberships
end

group1 = Group.new(.....)
group1.users = [User.find_by_id(2)]
group1.save!

it throws the exception: "users=" is one undefined method. So how can
i save the relationship in hasmanythrough?
