In our case, type in the following command in the terminal.Īs you can see, the following files were all instantly created by this command! Rails g resource (singular form of your model name) The command syntax that you have to use in this step is – #in terminal bundle install STEP 3: Create model, controller, database migration table and route via rails g resource command. The next step is to install bundle in the terminal. In the file explorer, scroll down and open Gemfile. Resource ‘*’, headers: :any, methods: end end insert_before 0, Rack::Cors do allow do origins ‘*’ # in config>initializers>cors.rb # lines 8-16 On line 10, change the code (origins ‘’) to (origins ‘*’) as shown below. Un-comment lines 8-16(NOTE: The corresponding code is pasted below for your reference, though line numbers may change.) Let’s enable CORS, So that others can access our data.Įxpand the following directories in your newly built Rails API’s file explorer to access the cors.rb file. Rails automatically disables CORS to prevent unauthorized access to your API. STEP 2: Enable CORS (Cross Origin Resource Sharing)ĬORS enables third parties to use your API. Go to the menu_api directory and open the API by typing the following into your terminal.Ĭode. The above command will create a new Rails API named menu_api. #in your terminal rails new menu_api –api To test our API, we will use a free tool called Postman.Ĭreate a directory for your new API, go to that directory and type the following command into the terminal. Fire up your server & postman to test API functionality.Create routes for index, show, create, update, and destroy actions.Define index, show, create, update, and destroy actions.Specify attributes and datatypes of menu item.Create model, controller, database migration table and route via rails g resource command.Enable CORS(Cross Origin Resource Sharing).We will follow the 8 Steps to create and test API functionality. The goal is to create an API of menu items available at a favourite fast food restaurant.

The Benefits of Ruby on Rails API Development for Users The Benefits of Ruby on Rails API Development for Developers In the weather example, the mobile app is the client and the bureau’s weather database is the server. Applications that transmit requests and responses are referred to as clients and servers, respectively. Related Post: 5 Best API Integration Tools Developers Need to KnowĪPIs are typically defined in terms of client and server. Your phone’s weather app “talks” to this system via APIs to provide you with daily weather updates. What is API?ĪPIs are mechanisms that let two software components communicate with one another using a set of definitions and protocols.įor instance, the software system of the weather bureau contains daily weather information. In this guide, we will discuss APIs and their benefits and also discuss one Ruby on Rails API tutorial. With just basic knowledge you can build a Ruby on Rails API. On top of that, Ruby on Rails Gems enable developers to create functionality without having to write code.ĭid you think that building a Ruby on Rails API is tough? Most of the services you use on a regular basis use some third-party API to enhance their functionality. There are adapters for almost all databases available, so you don’t need to worry about anything else.Įventually, you will need to use Ruby on Rails API if you want to add more functionality to your services. Ruby on Rails framework provides a wide range of tools right out of the box, allowing you to build complete applications very quickly.
