Has_many :through question

I am trying to create an association table using the “:through” option
in “has_many” but not having success. I have created the necessary
migrations of the association tables and run rake db:migrate

I have the following model:

class Group < ActiveRecord::Base
has_many :users, :through => :group_user
has_many :invites, :through => :group_invite, :class_name => “User”
belongs_to :owner, :class_name => “User”
end

class GroupUser < ActiveRecord::Base
belongs_to :group
belongs_to :user
end

Loading development environment (Rails 2.3.8)

g = Group.find(1)
=> #<Group id: 1, name: “My Group”, owner_id: 1, created_at: “2010-08-19
02:30:10”, updated_at: "
2010-08-19 02:30:10">

g.users << User.find(2)

association :group_user
