Ruby On Rails Course And Certification

What is Ruby on Rails?

Ruby on Rails is a web application development framework that presents Ruby developers with a time-saving method for writing web applications. Rails are one of the many web application frameworks in the world of web development and app programming. These frameworks are basically a collection of code libraries that give both app and web developers a readymade solution for carrying out time-consuming, and repetitive tasks like developing menus, tables, or forms on a website.

Ruby on Rails, is a server-side web application development framework that was developed in Ruby under the MIT License. Rails is an MVC (model–view–controller) framework, that provides developers with the default structures for a web service, a database, and web pages. It supports and facilitates the use of web standards such as XML or JSON for data transfer, HTML, CSS and JavaScript for designing the user interface. In addition to the MVC paradigm, Ruby on Rails fully supports the use of other well-known software engineering paradigms and patterns in a Rails application, and this includes several don't repeat yourself (DRY) rules, conventions over configuration (CoC), and the active record pattern.

Not only does the Ruby on Rails web framework take down the time that is spent on re-coding repetitive tasks, but by using Rails framework, Ruby developers keep their overall work cleaner, develop their apps to be less prone to bugs, and make it easier to troubleshoot when problems do occur. At the same time, Rails supports an overall method of best practices for Ruby on Rails developers that takes away the need to leave behind instructions and rationale for your coding decisions (by using configuration files) in the code that you write instead, Rails developers work from the shared common ground of Rails conventions.

What is Rails?

1. An extremely productive web-application framework.

2. Written in Ruby by David Heinemeier Hansson.

3. You could develop a web application at least ten times faster with Rails than you could with a typical Java framework.

4. An open-source Ruby framework for developing database-backed web applications.

5. Configure your code with Database Schema.

6. No compilation phase required.

Features of Ruby on Rails

There are many features of Ruby on Rails, below are some of them:

1. Symbol Garbage Collector: Transferring symbols opens up the possibility of several attacks in your software system. The symbol garbage collector collects and receives the symbols which help to prevent your system from several attacks.

2. Module #prepend: The module prepend allows ruby developers to include a module in front of the class that it was prepended.

3. Keyword Arguments: Ruby on Rails supports keyword arguments which help to reduce the memory consumption of your Rails application.

4. Turbolinks: In some cases, a web page reloads very slow because it is loading a full page from the server. Turbolinks 3 in Rails lets you reload only the content of the body, it doesn't reload the full page.

5. Action Cable: The Action Cable is a web framework that is used to extend Rails applications through Websockets to add some application functionality. It smoothly integrates WebSockets into the rest of the Ruby on Rails application. It allows you to easily add some real-time features into your Rails application.

Benefits of studying Ruby On Rails

There are many benefits of Ruby on Rails, and some of them are:

1. Development with Ruby on Rails is time-efficient.

2. Ruby on Rails is very consistent.

3. Ruby on Rails provides great quality and it promotes bug-free development.

5. Applications that are developed on Rails are highly scalable.

6. Rails applications are very secure.

6. Learning Ruby on Rails provides Job Opportunity and Career Advancement.

7. Learning Ruby on Rails Entrepreneurship Opportunity and Consultancy.

Strengths of Ruby on Rails

Ruby on Rails is made up of features that make you get your work done faster and efficiently, with tons of the following features functioning on one other.

1. Metaprogramming

In cases where other ruby frameworks make use of extendible code creation from the ground up, the Rail framework makes use of metaprogramming programs to create and programs. Ruby on Rails is one of the best choices for metaprogramming, and Ruby on Rails makes use of this feature very well. Ruby on Rails also makes use of code generation but depends much more on Metaprogramming for all the heavy work.

2. Active Record

Rails initiate the Active Record framework, which stores objects into the DB. The Rails version of the Active Record found the columns in a database schema and automatically joins them to your domain objects using metaprogramming.

3. Convention over configuration

The majority of the web development frameworks for .NET or Java make sure you to write long lines and pages of configuration code. If you adhere to the suggested naming techniques, Ruby on Rails doesn't need all those configurations.

4. Scaffolding

Engineers often create temporary code in the initial stages of development in other to help get an application up fast and visualized how the major components work in accordance. Ruby on Rails do this automatically, It creates most of the scaffolding you'll need.

5. Built-in testing

Ruby on Rails generates very simple automated tests that you can then rewrite or extend. Ruby on Rails also generates supporting code that is called harnesses and fixtures that makes writing test cases easier to write and execute. Ruby can then help execute all of your written automated tests with the use of the rake utility.

6. Three environments

Ruby on Rails provides a programmer with three default environments: development, testing, and production. Each of these environments acts slightly differently, therefore making your entire software development cycle seamless and easier. For example, Ruby onRails generates a new copy of the Test database for each test that is run.
