We’re adding email and password_digest columns here, which are the basic columns required to register or authenticate a user. Run rake db:migrate to run the migration.
GENERATE RAILS MASTER KEY CODE
Add the following code to this file, which will add the columns we need: create_table :users do |t| This command will create a migration file under db/migrate called XXX createusers, where XXX is the current date. The application will authenticae users, so let’s create a User model. We’ll begin by building a model for our app. NOTE: This Tutorial is aimed for API-based authentication. Today we’re going to explore building our own custom JWT-based authentication system from scratch. devise tokenauth is a library that does what Devise does, but with tokens instead of sessions. For example, Devise doesn’t work very well with API-based systems, which is why we have the devise tokenauth gem. However, often times we don’t need many of the parts it provides. For Rails, we have a number of authentication systems, the prominent one being Devise.ĭevise is an authentication engine that runs as part of our application and does all the heavy lifting when it comes to authentication. These libraries take away much of the groundwork required to setup an authentication system, providing “magic” with what’s happening behind the scenes. There are innumerable libraries and frameworks that provide various options to perform authentication one way or another. Authentication is one of the vital parts of any web application.
