Answer 1

You should change the 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
