Ruby on Rails web framework is a free application to increase the speed and ease with which Web sites, databases can be created and offers skeleton code frameworks from the outset goals. Often shortened Rails or RoR, Ruby on Rails project in the Ruby programming language and applications using the Rails framework were written, developed with the Rails framework developed with the design pattern Model-View-Controller.
Rails is developing a complete framework for web applications, back up the database using the Model-View-Controller. From the Ajax in the view, and demand response in the controller, the domain model wrapping the database gives you a pure Ruby Rails development environment. To go live, just add a database and Web server.
The basics of Ruby on Rails conventions contain Configuration (CDC) and Do not Repeat Yourself (DRY).
Do not Repeat Yourself means that information in one place without ambiguity, as the use of Active Record, the developer has not specified column names from the base class definitions. Instead, Ruby can retrieve this information from the database.
Convention over configuration , a developer only needs to specify unconventional aspects of the application. For example, if a sale of the class in the model, the corresponding table in the database is called sales by default. Only if we depart from this convention, such as calling the table products_sold You need to write code that name.
Because of these strict requirements Rails is often called opinionated software that was a sticking point for many critics of Rails.
