Create a Rails API App

Published about 7 years ago

Command line for creating new app

Let's first create our API app. The --api makes our app only have the essential code and cuts out any unneeded code an API wouldn't need. The -T tells it not to install any test suite. The -d specifies which database should be used.

rails new app_name --api -T -d postgresql

Create the database.

rails db:create

Use a scaffold.

rails g scaffold NAME title:string description:string file_url:text image_url:text

Migrate it to the database.

rails db:migrate

Enable CORS gem in the gemfile and then uncomment the section in initializers/cors.rb
