This course uses Rails 3.2. If you're using Rails 4 and above, the code shown in the videos will not work (it's outdated). attr_accessible is one of the differences. Rails 4 uses Strong Parameters instead for this purpose.

Sorry I am new to rails does that mean we can fix this with replacing attr_accesible with strong parameter? how? I was about to downgrade to 3.2.

It's better to downgrade to 3.2 and use old gems like Jason does. Trying to translate this app into Rails 4 is not so easy if you're new to Rails.

I just face into this problem maybe this could help !

Using Rails 4 the solution is to create a controller for user_friendships ( in the next video Jason create that controller, so you will need it anyway)

rails g controller UserFriendships`

And set the strong parameters :

class UserFriendshipsController < ApplicationController


  private
  def params_user_friendship
    params.require(:friendship).permit(:user, :friend, :user_id, :friend_id)
  end

end
