Learn how the Ruby On Rails framework simplifies web application programming with the “model-view-controller” design paradigm and the Ruby programming language. Ruby On Rails (Rails) is an open-source framework and one of the most popular programming languages for web application programming.

Ruby on Rails organizations don't need to revamp each and every bit of code during the time spent web application advancement, in this manner decreasing the time spent on essential undertakings. The Ruby on Rails structure essentially streamlines the cycle of site and application working by taking basic dull undertakings off the engineers' shoulders, for example, the production of structures, tables, and menus. Designers don't need to assemble another site or web application without any preparation, as they can use out-of-the-case answers for redundant errands.

## Ruby on Rails MVC Framework

MVC is an example of the design of a product application. It divides an application into the some segments:

- Models for handling data and business logic
- Controllers for handling the user interface and application
- Views for handling graphical user interface objects and presentation

## Model

It keeps up the connection between the items and the information base and handles approval, affiliation, exchanges, and that's just the beginning. This subsystem is actualized in the ActiveRecord library, which gives an interface and authority between the tables in a social information base and the Ruby program code that controls information base records. Ruby strategy names are naturally produced from the field names of information base tables.

## View

It is an introduction of information in a specific configuration, set off by a regulator's choice to introduce the information. They are content-based format frameworks like JSP, ASP, PHP, and extremely simple to coordinate with AJAX innovation. This subsystem is executed in ActionView library, which is an Embedded Ruby (ERb) based framework for characterizing introduction layouts for information introduction. Each Web association with a Rails application brings about the showing of a view.

## Controller

The office inside the application that coordinates traffic, from one viewpoint, questioning the models for explicit information, and then again, putting together that information into a structure that fits the requirements of a given view. This subsystem is executed in ActionController, which is an information intermediary sitting among ActiveRecord and ActionView.

## Tips on how to build web app using ruby on rails 

## Use bundlers 

Bundler deals with the advancement of dependencies in the Ruby application. It does that by perusing the Gemfile, which is set in the application's root index. In this way, to have all running easily you require to introduce all the necessary pearls. You can produce the Gemfile with the ruby on rails new order. After you guarantee that you have all the default diamonds, run the group introduce order.

## Add users and authentication

First of all, install the Devise gem and generate the user model. Integrate it with all users bookmarks. The last, add an authentication check to the BookmarksController that is automatically created by the scaffold command.

## Use server matrix 

A good way to improve performance is to understand how much server load is needed by the Ruby on Rails development process. Telegraf can be used to collect metrics, and Grafana can be used to give alerts about anything going wrong.
