Localhost is the default web address when you are developing locally on a web server. It can be used to access webpages that are stored on the same computer as the web server. However, when you are ready to take your application live, you will need to change the address from localhost to a domain name. In this tutorial, we will show you how to change the address from localhost to a domain name in Rails.
What is Localhost?
Localhost is the default domain name used when developing a web application locally. This means that the web application is stored on the same computer as the web server and can be accessed from the same computer. Localhost is the most common way of developing web applications because it is quick and easy to set up.
When you are developing with localhost, all of the requests for the web application will be directed to the local web server. This means that the web application can be tested without having to deploy it to a live web server.
Why Change the Address from Localhost?
Once you have finished developing the web application, you will need to deploy it to a live web server. This means that you need to change the address from localhost to a domain name. This will allow the web application to be accessed from anywhere in the world.
When you are ready to deploy your application, you will need to purchase a domain name and point it to your web server. This is the process of changing the address from localhost to a domain name.
How to Change the Address from Localhost in Rails
The first step is to purchase a domain name and point it to your web server. You can do this by logging into your web hosting provider’s control panel and setting up a domain name. Once you have done this, you can then start to change the address from localhost to your domain name.
The next step is to open the Rails application in your text editor or IDE. You will then need to locate the config/environments/production.rb file and modify the following line:
config.action_controller.default_url_options = {host: 'localhost'}
You will need to change this line to the following:
config.action_controller.default_url_options = {host: 'your-domain-name.com'}
This will change the address from localhost to your domain name. The next step is to open the config/routes.rb file and change the following line:
root to: 'home#index'
You will need to change this line to the following:
root to: 'home#index', host: 'your-domain-name.com'
This will ensure that all requests are directed to your domain name. The final step is to restart your web server. This will ensure that the changes you have made take effect.
