Rails Model Complex Associations -

i have user model , through table between user's called invite model.

i want users able invite others, invited , have association created.

my migration file looks this:

class createinvites < activerecord::migration   def change     create_table :invites |t|       t.integer :invited_id       t.integer :inviter_id       t.timestamps     end end 

in invite model have following:

class invite < activerecord::base       belongs_to :invited, :class_name => 'user'     belongs_to :inviter, :class_name => 'user' end 

i unsure how construct user model appropriate associations. want user belong 1 inviter , have many inviteds. how should update user model appropriately.

class user < activerecord::base   has_many :sent_invites, :class_name => "invite", :foreign_key => :inviter_id   has_many :inviteds, :through => :sent_invites    has_one :invite, :foreign_key => :invited_id   has_one :inviter, :through => :invite end 

sidebar, idea add indexes foreign keys so:

class createinvites < activerecord::migration   def change     create_table :invites |t|       t.references :invited       t.references :inviter       t.index :invited_id       t.index :inviter_id       t.timestamps     end   end end
