Well-known sites that use Ruby on Rails include Airbnb, Bloomberg, Crunchbase, Dribbble, GitHub and Shopify.ĭavid Heinemeier Hansson extracted Ruby on Rails from his work on the project management tool Basecamp at the web application company 37signals. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Python Catalyst in Perl Laravel, CakePHP and Yii in PHP Grails in Groovy Phoenix in Elixir Play in Scala and Sails.js in Node.js. Ruby on Rails' emergence in 2005 greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development.

In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing.
Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages.

# Copy the code into your application's db/seeds.rb file.Ruby on Rails (simplify as Rails) is a server-side web application framework written in Ruby under the MIT License.
Other than that, we’re setting up our Rails environment, booting the application and running any available migrations. Because we’re using Bundler, our gem is actually required in the dummy Rails app via our Gemfile at test/dummy/config/application.rb. One thing to notice, which is unusual for a testing set-up helper, is that we aren’t requiring our local gem code anywhere in the test helper. S.executables = `git ls-files`.split("n").map S.add_dependency "activesupport", "~> 3.0.7" S.description = "A simple Rails 3 engine gem that adds a team page to any Rails 3 application." # Enginex project in your Rails apps through Git. # Provide a simple gemspec so that you can easily use your Require File.expand_path("./lib/team_page/version", _FILE_) First, our team_page.gemspec and our Gemfile need a little love. To set up our gem, we’ll modify a few files. With this, you will end up with a project in the team_page directory containing the standard Enginex scaffolding.

To begin, run the following from the command line in your standard projects directory: gem install enginex It provides basic set-up, including a test Rails application, which you’ll need to get started. This tool protects you from many of the gotchas that engine gem developers face. Jose Valim, a core Rails contributor, has created a tool named Enginex, which scaffolds Rails 3-compatible engine gems.
In this post, we’ll walk through the process of creating an engine gem that you would use to create a database-backed team page displaying a list of employees. This is a great candidate for a Rails engine gem because the functionality will change very little and can be abstracted to a common set of requirements. A common requirement for such websites is a page listing all of the employees at a company and some basic information about them. Let’s say you build a lot of websites for small businesses. Now, unless you like writing a lot of code, this is great news, because it means you can write an engine once and use it over and over again. An engine can have its own models, views, controllers, generators and publicly served static files. A Rails engine is a prepackaged application that is able to be run or mounted within another Rails application. Since Rails 3 was released, developers have been writing Rails engines in a new clean style that can be packaged as RubyGems. This process can be used for any engine gem you feel you need, and it can speed up development time and improve the reliability and maintainability of your code bases. In this article, Ryan Cook walks you through the process of creating an engine gem that you would use to create a database-backed team page displaying a list of employees.
