How to Set Up a New Rails Application with User Signup and Email Confirmation

Are you looking for a quick way to set up a new Ruby on Rails application with user signup and email confirmation? Look no further! With this guide, you'll be able to create a fully functional rails app in no time.

To get started, simply run the following command: `rails new rails4-with-user-signup -d postgresql`. This will create a brand new Rails 4 application using PostgreSQL as your database.

Once the application is created, navigate to the root directory of your project and open the `config/environments/development.rb` file. Add the following lines to the bottom of the file: `config.action_mailer.default_url_options = ...`. This will allow you to send emails in development mode.

Next, follow the instructions on the Devise wiki page for adding :confirmable to your Users model. This will enable email confirmation for new users.

Finally, commit your changes and run the following command: `rails generate devise:install`. This will install the necessary files and configure your Rails application for user signup and authentication.

If you're using OS X with PostgreSQL, you may encounter an error when running the command above. To fix this, simply adjust the `config/database.yml` file to point to the correct socket location.

That's it! You've now successfully set up a new Rails application with user signup and email confirmation. You can test your app by navigating to `localhost:3000/users/sign_up` and filling out the sign-up form.
