Rails console Association error

I have tried to use the rails console to run the following: Teamplayer.includes(:live_player)

It tells me: Association named 'live_player' was not found on Teamplayer; perhaps you misspelled it?

so the tables are named live_players and teamplayers respectively. There is also another table called teams but that will only make sense in the models below:

Liveplayer:

class LivePlayer < ActiveRecord::Base has_many :teamplayers has_many :fteams, :through => :teamplayers end

Fteam:

class Fteam < ActiveRecord::Base belongs_to :liveplayer end Teamplayer:

class Teamplayer < ActiveRecord::Base belongs_to :live_player belongs_to :fteam end

so what is problem with this. I have been at this for days
