Unknown Action for Followers on UsersController - Rails Tutorial

I'm trying to implement a Follower system similar to Twitter in my app. I'm implementing the Follower system explained in Michael Hartl's Rails Tutorial:

http://ruby.railstutorial.org/chapters/following-users

I have noticed an issue after completing the example:

Going to /users/(id)/following or /users/(id)/followers displays the following error messages:

Unknown action

The action 'following' could not be found for UsersController

or 

Unknown action

The action 'followers' could not be found for UsersController

What puzzles me about these errors is that I did define these actions in the UsersController:

def following
    @title = "Following"
    @user = User.find(params[:id])
    @users = @user.followed_users.paginate(page: params[:page])
    render 'show_follow'
  end

  def followers
    @title = "Followers"
    @user = User.find(params[:id])
    @users = @user.followers.paginate(page: params[:page])
    render 'show_follow'
  end

Here is my routes.rb file just in case the issue lies there:

AppName::Application.routes.draw do

  #get "users/index"

  #get "users/show"



authenticated :user do
    root :to => 'home#index'
  end
  root :to => "home#index"
  devise_for :users
  resources :users do
    member do
      get :following, :followers
    end
  end
  resources :works
  resources :relationships, only: [:create, :destroy]
end

Additional information: I'm using Devise to handle user authentication.

FIXED:

The issue was the placement of the following and followed actions in the Users Controller.

resources :users do
  member do
 get  :following 
 get  :followers
    end

 end

the above routes work, and provide following_user_path and followers_user_path routes respectively

In your config/routes.rb, the member actions must be one per line:

resources :users do
  member do
    get :following
    get :followers
  end
end
