Now that you know what is Ruby on Rails, let’s explore how this web development framework came about:

Birth of Ruby on Rails

The story began in the early 2000s when a Danish programmer named David Heinemeier Hansson was working on a project for the project management tool Basecamp. Frustrated with the complexity and verbosity of existing web development frameworks, he created a more elegant and productive alternative.

Ruby’s Influence

Hansson chose the Ruby programming language as the foundation for this new framework due to its clean and intuitive syntax. Ruby’s creator, Yukihiro Matsumoto, had designed the language to prioritize developer happiness and productivity, making it an ideal match for Hansson’s vision.

Rails Emerges

In 2004, David Heinemeier Hansson released the first version of Ruby on Rails, also known as Rails or RoR. Rails introduced a groundbreaking concept: the Model-View-Controller (MVC) architecture, which made it easier to develop and maintain web applications. This architectural pattern allowed for a clear separation of concerns, simplifying code organization and enhancing collaboration among developers.

Rapid Adoption

Ruby on Rails quickly gained traction in the web development community. Its simplicity, convention over configuration approach, and elegant code structure attracted developers looking for a more enjoyable and productive development experience. Popular web applications like Twitter, Airbnb, and GitHub have been built on Ruby on Rails, further solidifying its reputation.

Key Characteristics of Ruby on Rails

Key Characteristics of Ruby on Rails

Below are a few key characteristics of Ruby on Rails that have contributed to its popularity in the web application framework community:

1. MVC Architecture

One of the most significant characteristics of Ruby on Rails is its adherence to the Model-View-Controller (MVC) architectural pattern. This separation of concerns allows developers to keep their application’s logic, presentation, and data management neatly organized.

The ‘Model’ represents the data and database interactions, the ‘View’ deals with the user interface and presentation, and the ‘Controller’ acts as the intermediary, handling user requests and managing the data flow between the Model and View. This clean separation makes code more maintainable and promotes scalability, a key advantage for complex web applications.

2. Active Record

Active Record is a prominent feature of Ruby on Rails that simplifies database operations. It provides an object-oriented interface to the database, allowing developers to work with database records using Ruby classes and methods. Developers can interact with data by defining models corresponding to database tables without manually writing complex SQL queries.

This abstraction simplifies database operations, reduces the risk of SQL injection, and enhances code readability. Active Record’s intuitive syntax streamlines database CRUD (Create, Read, Update, Delete) operations, making it a powerful tool for developers.

3. Convention over Configuration

Another distinguishing characteristic of Ruby on Rails is the principle of ‘Convention over Configuration’ (CoC). This philosophy streamlines development by providing sensible defaults and conventions that eliminate the need for extensive configuration.

Rails developers follow naming conventions for files, directories, and database tables, reducing the amount of code they need to write. CoC allows developers to focus on building unique features and functionality rather than spending time on repetitive configuration tasks. This approach boosts productivity and promotes consistency across Rails projects, making it easier for developers to collaborate and maintain code.

4. Simple Testing Tool

One of Ruby on Rails’s cornerstones is its built-in testing framework. Rails encourages Test-Driven Development (TDD) and provides developers with a simple and effective testing toolset. The framework’s integrated testing suite allows developers to write unit, functional, and integration tests easily.

This promotes code reliability and ensures that changes to the application don’t introduce unexpected bugs. The simplicity and robustness of Rails’ testing tools have contributed significantly to the framework’s popularity, as it empowers developers to create well-tested and dependable applications.

5. Automated Deployment

Deploying web applications can be complex and error-prone, but Ruby on Rails simplifies it considerably. Rails has many deployment options and tools that make the process smooth and automated. Popular tools like Capistrano allow for automated deployment scripts, making deploying applications to various hosting environments easy.

The Rails community has embraced containerization and orchestration technologies like Docker and Kubernetes, further streamlining deployment and scaling processes. With Rails, deploying and managing web applications becomes straightforward, saving developers valuable time and effort.

6. Simple Programming Language:

The Ruby programming language is at the core of Ruby on Rails. Ruby is celebrated for its simplicity and readability, making it an ideal choice for beginners and experienced developers. Ruby’s syntax is intuitive and elegant, emphasizing human-friendly code. This simplicity accelerates the development process and enhances collaboration among team members.

Ruby’s dynamic nature allows developers to express complex ideas with concise and natural language constructs. Rails developers can focus on solving business problems rather than wrestling with complex syntax, leading to more efficient and enjoyable development experiences.

Strengths of Ruby on Rails

Once you have understood what is Ruby on Rails, it is important to consider its strengths and weaknesses to determine whether it is a suitable web application framework for you:


One of the most notable strengths of Ruby, and by extension Ruby on Rails, is metaprogramming. Metaprogramming refers to writing code that writes other code, a powerful feature that Rails leverages extensively. This capability is intrinsic to Ruby, which Rails utilizes to simplify and automate many aspects of web application development.

It enables developers to write concise, expressive code that dynamically defines methods, classes, and modules. Metaprogramming in Rails boosts productivity and enhances the framework’s flexibility, allowing developers to create elegant, DRY (Don’t Repeat Yourself) code.

Active Record

Active Record, Rails’ Object-Relational Mapping (ORM) system, is another significant strength. Active Record simplifies the way developers interact with databases. It allows Ruby objects to be seamlessly mapped to database tables, abstracting complex SQL queries into simple, readable Ruby code.

This means developers can perform database operations without writing raw SQL, reducing the risk of SQL injection attacks. Active Record also supports a variety of database operations, including transactions, associations, validations, and migrations, making it a robust and secure tool for database management in web applications.

Convention of Configuration

Rails’ ‘Convention over Configuration’ philosophy sets it apart from other web frameworks. This principle means that Rails comes with a set of conventions that, when followed, reduce the need for configuring every aspect of the application.

It assumes sensible defaults for what it needs to function, allowing developers to focus on the unique aspects of their application rather than on boilerplate code. This approach significantly accelerates development, minimizing the decisions developers have to make, leading to faster project kickoffs and fewer bugs.


Scaffolding in Rails refers to the automatic generation of a set of models, views, and controllers, which form the basic structure of a web application. This feature is particularly useful in the early stages of development, as it provides a quick and easy way to get a working prototype up and running.

Scaffolding also helps new developers understand the MVC (Model-View-Controller) architecture. It generates a clear, consistent, and functional example of how components interact in a Rails application.

Built-in Testing

Testing is an integral part of any robust development process, and Rails excels in this area with its built-in testing framework. Rails encourage test-driven development (TDD), including a comprehensive suite of testing tools covering unit, functional, and integration tests.

The framework integrates seamlessly with various testing libraries and tools, making it easier for developers to write and run tests. This built-in testing support ensures Rails applications are more stable, maintainable, and less prone to bugs.

Limitations of Ruby on Rails

1. Obscurity due to Convention

Ruby on Rails follows the principle of ‘Convention over Configuration’ (CoC), which enforces certain naming conventions and best practices. While this Convention can improve code consistency and collaboration, it can also be limiting for developers who prefer more flexibility and customization.

Solution: To overcome this limitation, developers can use Rails’ flexibility and override conventions when necessary. Developers can balance Convention and customization by understanding the framework deeply and knowing when to deviate from conventions.

2. Boot Speed

One of the criticisms often directed at Ruby on Rails is its slower boot speed compared to some other frameworks. A Rails application’s initialization process can be relatively slow, affecting development speed and server responsiveness.

Solution: To mitigate boot speed issues, developers can use techniques like code splitting, caching, and optimizing database queries. Tools like Spring and Bootsnap can also help improve Rails’ boot time.

3. Multi-threading

Ruby on Rails has historically faced challenges with multi-threading due to its Global Interpreter Lock (GIL). The GIL restricts multiple threads from executing Ruby code in parallel, limiting the benefits of multi-threading in certain scenarios.

Solution: To circumvent this limitation, developers can use other concurrency models like multi-processing or external services for parallel processing tasks. Alternatively, they can use JRuby, which runs on the Java Virtual Machine (JVM) and does not have a GIL limitation.

Why Use Ruby on Rails?

Why Use Ruby on Rails

One commonly asked query after ‘what is Ruby on Rails’ is why use Ruby on Rails? Let’s explore the answer below:

Easy to Learn

One of the most appealing aspects of Rails is its simplicity and ease of learning, especially for those already familiar with Ruby, the language it’s built on. Rails follows the principle of ‘Convention over Configuration,’ which means that it makes assumptions about what you want to do and how you will do it, so you don’t have to specify every little detail.

This significantly reduces the amount of code you need to write and increases the development speed. This is a blessing for beginners as it allows them to quickly grasp the basics and start building functional web applications in no time.


Rails embraces Test-Driven Development (TDD), an approach to software development in which tests are written before the actual code. In TDD, developers first define what the application should do through tests and only then write the code to pass these tests.

This methodology allows developers to rely on the framework for guidance and encourages a more thoughtful and deliberate design process, leading to more robust and well-architected systems. TDD in Rails helps catch issues early in the development cycle, reducing the cost and effort associated with fixing bugs in later stages.


Security is a paramount concern in web development, and Rails excels in this area. It offers built-in mechanisms to protect against common vulnerabilities like SQL injection, cross-site scripting, and cross-site request forgery (CSRF).

These features are enabled by default, ensuring that even less experienced developers create secure applications. The Rails community is vigilant about identifying and patching vulnerabilities, so security updates are regularly released and easy to implement.


Rails is built on Ruby, a language celebrated for its readability. This readability is a significant asset for maintaining and scaling web applications. Code that is easy to read and understand is easier to modify, debug, and update. This clarity benefits individual developers and facilitates smoother collaboration within teams, as the codebase is more accessible to all team members.


Flexibility is another hallmark of Rails. While it provides structure through the MVC (Model-View-Controller) architecture, it also allows developers enough flexibility to tailor applications according to specific needs. Rails support many web applications, from small-scale solutions to large, complex systems. Its modularity and the vast ecosystem of ‘gems’ (libraries) enable developers to extend and customize their applications as needed.

When to Use Rails and When Not to Use Rails

When to Use Rails and When Not to Use Rails

When to Use Ruby on Rails

Rapid Development and MVPs

  • Speed and Efficiency: Rails is well-known for its ability to speed up development. This makes it an excellent choice for startups and businesses looking to develop a Minimum Viable Product (MVP) quickly. Its extensive libraries and ‘convention over configuration’ approach allow developers to get a project up and running in a fraction of the time it might take with other frameworks.

Database-Backed Applications

  • ORM and Migration Support: Rails comes with ActiveRecord, an Object-Relational Mapping (ORM) system that makes working with databases intuitive and efficient. This is ideal for applications that require robust database interactions.

Conventional Projects with Standard Features

  • Built-In Solutions: Rails offers out-of-the-box solutions for many standard web application features, such as user authentication and session management. This makes it a good fit for projects that don’t require highly unconventional solutions where standard practices are applicable.

Projects Requiring Scalability and Good Structure

  • Scalable and Structured: Rails’ MVC framework ensures that applications are well-structured, making them easier to scale and maintain in the long run.

When Not to Use Ruby on Rails

Highly Specialized Applications

  • Custom Solutions: For projects that require highly specialized, non-standard features, Rails’s conventions might be more of a hindrance than a help. A more flexible framework, or even a microservices architecture, might be better suited in these cases.

Microservices-Based Architecture

  • Large-Scale Systems: While Rails can support microservices architecture, it may not always be the best fit, especially for complex, large-scale systems where different application components might require different technologies.

Real-Time Applications

  • Limited Real-Time Capabilities: Applications that require extensive real-time features, like messaging apps, may limit Rails’ capabilities. While solutions like ActionCable exist, other frameworks might offer more robust support for real-time features.

High-Performance, Low-Latency Applications

  • Performance Intensive: Rails might not be optimal for applications with critical performance and low latency. In these scenarios, languages and frameworks that offer closer control over system resources might be preferable.
