Home Page

Right now, visiting the application root (/) will display our rather useless welcome#index view. Let's edit WelcomeController to do something a little more sensible.

We'll add the before_action to redirect unauthenticated users to the login page. We'll send logged in users to new_note_path.

app/controllers/welcome_controller.rb

class WelcomeController < ApplicationController
  before_action :authorize_user
  def index
    redirect_to new_note_path
  end
end

$ git add .
$ git commit -m "Redirect root url depending on logged in status."

We no longer need the welcome#index view template.

$ git rm app/views/welcome/index.html.erb
$ git commit -m "Remove welcome/index view."
