Hi Lenka,

Could you please copy/paste in your app/views/application.html.erb and app/models/application.rb code?

Thanks!

I think maybe you meant app/controllers/application_controller.rb for the second one. There is no “app/models/application.rb”…

@lenkie Good job formatting your code - just remember to put the backticks (`) on their own line before and after the code :slight_smile:

And you’re correct about the file, thanks for pointing that out. Try adding this line to line 2 of application_controller.rb:

helper_method :current_user
5

OK thanks. That helped bring up the login screen but when I log in, it says “Not found”…

@lenkie Could you post a screenshot?

Also, if I could see your config/routes.rb, I think that’s where the problem is :slight_smile:

7 
Rails.application.routes.draw do
  root 'albums#index'
  get 'albums' => 'albums#index'
  get 'albums/new' => 'albums#new'
  get 'albums/:id' => 'albums#show', as: :album
  post 'albums' => 'albums#create'
  
  get 'signup'  => 'users#new' 
  resources :users
  
  get '/login' => 'sessions#new'
  post 'login' => 'sessions#create'
  
  delete 'logout' => 'sessions#destroy'
 
end

@lenkie Hm, so far, all of your code looks fine :sweat:

If refreshing your browser doesn’t change anything, could you post your sessions_controller.rb code?

9 
class SessionsController < ApplicationController
  def new
  end
  
  def create
  @user = User.find_by_email(params[:session][:email])
  if @user && @user.authenticate(params[:session][:password])
    session[:user_id] = @user.id
    redirect_to '/'
  else
    redirect_to 'login'
  end 
end
  
  def destroy
    session[:user_id] = nil
    redirect_to '/'
  end
  
end

@lenkie I’m not finding any problems in your code, so I’m not sure what’s wrong :confused:

You did create an account in the previous exercise (I think exercise 4), right? I don’t think not having an account would cause an error, but I’m not sure what else the problem could be.

11

OK, I had already created an account but I went back and did it again, just to see if anything changed, and it did. So then I was able to sign in in step 11. Thanks. I guess there’s some bug in the program or something. Anyway, moving on :slight_smile:
