I additionally had to make app/controllers/application_controller.rb look like the following to get the sign in to happen:
class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exceptionThen I had to make app/views/layouts/application.html.erb look like this:
before_filter :require_login
before_filter :check_if_devise
private
def check_if_devise if params[:controller].include? "devise/registrations" and params[:action].include? "create" end end
def require_login if not current_user and not params[:controller].include? "devise" redirect_to new_user_session_path end end
end

And at this point I finally get a login for the site that looks like this:
The commands that I used for this project.
Create the heroku project and copy the given command to check out the project locally.
git clone git@heroku.com:universalnewsaggregator.git -o heroku
rails new universalnewsaggregator
cd universalnewsaggregator
vi Gemfile

rake db:migrate
vi apps/views/layouts/application.html.erb
vi app/controllers/application_controller.rb
vi app/views/layouts/application.html.erb
rails generate scaffold news
vi config/routes.rb
