you should change code in user model to
class user < activerecord::base has_many :user_friendships has_many :friends, -> { where(user_friendships: { state: "accepted"}) }, through: :user_friendships has_many :pending_user_friendships, -> { where(state: "pending") }, class_name: 'userfriendship', foreign_key: :user_id has_many :pending_friends, through: :pending_user_friendships, source: :friend end
