Ruby on Rails also known as RAILS is an open-source server-side web application development framework that is written in Ruby, an object-oriented programming language similar to Perl and Python. It is considered one of the most popular Ruby libraries developed by David Heinemeier Hansson under the MIT license. Ruby on Rails uses Model-View-Controller (MVC) architectural pattern that separates a web application code into three interconnected parts:
The Model holds the data structure of the application
View represents the visual part of the application
The Controller contains the business logic of the application that connects the data to the View
Action pack, a manager of controller and view functions
Rapid Prototyping, using the Rails Ajax helpers
Active record, an object-relational mapping layer
Action Mailer, hooks into the Mail observer and interceptor methods
Rails has been used to develop many types of web applications that spans both the frontend and the backend. The View handles the front-end by generating the web pages seen on the browser, whereas, the model and controller handle the backend of the application.
It uses Metaprogramming techniques to write program codes
It allows the faster launch of web application
It helps in maintaining and avoiding problems with migration
Using Ruby on Rails makes the application faster and safer
It is cost-effective which will save you a lot of money
With the latest functionalities, it is easy to update the application
A project has heavy traffic
A long-term project which needs large transformation and updates
A project that requires a wide range of complex functionalities
Develop a minimum viable product (MVP) or short prototype
Ruby on Rails uses MVC architecture which contains three components- model, view, and controller. MVC is generally used for developing user interfaces that divide the data into these three interconnected components so that it can separate the internal representation of the information from the way it presents to and get from the user.
Metaprogramming is a technique by which you can write a code in such a way that writes code by itself dynamically during runtime. This means you can define classes and methods during runtime. Ruby on Rails supports MetaProgramming.
Rails uses the dynamism of Ruby language that utilizes a set of conventions to ease up the development process. It is a software design paradigm used by frameworks to decrease the number of decisions that a developer is required to make without losing flexibility and don’t repeat yourself (DRY) principles.
This feature allows the developers to define how the application database works. The framework automatically generates the required program code according to the given definition from the application database. The scaffolding technique creates interfaces automatically.
Rails provided skeleton test codes while developers are creating their controllers and models. By testing, you can ensure your code adheres to the desired functionality even after major code refactoring. Good testing reduces the number of bugs, improves the quality of the software, and makes our work easier in the long run.
Ruby on Rails provides active records which is a powerful library that allows the developer to design the database interactive queries.
