What did we just do?
- We created a model named User.
- In the model, we used the method
has_secure_password. This method adds functionality to save passwords securely.
- In order to save passwords securely,
has_secure_password uses an algorithm called bcrypt. To use bcrypt, we added the
bcrypt gem to the Gemfile.
Now that the User model is set up, let's continue by adding columns to the migration files.
