Ruby on Rails (RoR) is an open-source web application framework written in the Ruby programming language. It is designed to make programming web applications easier and faster by providing a set of tools and conventions to help developers write code.
Ruby on Rails (RoR) is a web application framework written in the Ruby programming language. It is designed to make programming web applications easier and faster by providing a set of tools and conventions to help developers write code. RoR is based on the Model-View-Controller (MVC) architectural pattern, which separates the application's data, business logic, and user interface into three separate layers.
RoR is designed to be highly extensible, allowing developers to create custom applications quickly and easily. The framework provides a set of libraries and tools that allow developers to quickly create database-backed web applications. RoR also provides a set of conventions that make it easier for developers to quickly create applications without having to write a lot of code.
RoR has a large and active community of developers who have contributed to the framework. This community has created a number of plugins, libraries, and tools to help developers build applications faster.
Ruby on Rails was first released in 2004 by David Heinemeier Hansson. It was inspired by the Ruby programming language and the Model-View-Controller (MVC) architectural pattern.
RoR quickly gained popularity among developers due to its ease of use and extensibility. It was used to create a number of popular web applications, such as Basecamp, GitHub, and Shopify.
RoR provides a number of features that make it easier for developers to create web applications. These features include:
Model-View-Controller (MVC) architectural pattern: The MVC pattern separates the application's data, business logic, and user interface into three separate layers. This makes it easier for developers to create custom applications quickly and easily.
Database support: RoR provides support for a number of popular databases, including MySQL, PostgreSQL, and SQLite.
Automated testing: RoR provides a set of tools to help developers create automated tests for their applications. This makes it easier for developers to ensure that their applications are working correctly.
Plugins and libraries: RoR has a large and active community of developers who have contributed a number of plugins, libraries, and tools to help developers create applications faster.
To illustrate how RoR works, let's create a simple web application that displays a list of books.
First, we need to create the database. We can do this using the command line or a graphical tool such as phpMyAdmin.
Next, we need to create the models. We can do this by creating a Book model with the title, author, and year fields.
Next, we need to create the views. We can do this by creating a Books view that displays a list of books.
Finally, we need to create the controller. We can do this by creating a BooksController that handles requests for the Books view.
Pros:
Cons:
One of the most controversial aspects of RoR is its use of the Model-View-Controller (MVC) architectural pattern. While this pattern makes it easier for developers to create custom applications quickly and easily, it can also lead to code that is difficult to maintain and debug.
Ruby on Rails is closely related to the Ruby programming language. It is also related to other web application frameworks such as Django and ASP.NET.
