Ensure you have defined default url options in your environments files. Here is an example of default_url_options appropriate for a development environment in config/environments/development.rb: config.action_mailer.default_url_options ={host: 'localhost', port: 3000 } In production, :host should be set to the actual host of your application. 2. Ensure you have defined root_url to *something* in your config/routes.rb. For example: root to: "home#index" 3. Ensure you have flash messages in app/views/layouts/application.html.erb. For example: <p class="notice"><%= notice %></p> <p class="alert"><%= alert %></p> 4. You can copy Devise views (for customization) to your app by running: rails g devise:views =============================================================================== ∴ vi config/environments/development.rb ∴ vi app/views/layouts/application.html.erb ∴ rails g devise:views ∴ rails generate devise User ∴ cat app/models/user.rb ∴ cat db/migrate/20180131170346_devise_create_users.rb ∴ rails db:migrate << restart server as recomended >> ∴ vi app/controllers/application_controller.rb before_action :authenticate_user! << add affter forgery line .. >>
