What is Ruby on Rails ?

Ruby on Rails is a web application framework written in Ruby, a dynamic programming language.

Ruby on Rails uses the Model-View-Controller (MVC) architecture pattern to organize application programming.

  • A model in a Ruby on Rails framework maps to a table in a database
  • A controller is the component of Rails that responds to external requests from the web server to the application, and responds to the external request by determining which view file to render
  • A view in the default configuration of Rails is an erb file. It is typically converted to output html at run-tim

what is so special about Rails

  • Other frameworks use extensive code generation, which gives users a one-time productivity boost but little else, and customization scripts let the user add customization code in only a small number of carefully selected points
  • Metaprogramming replaces these two primitive techniques  and  eliminates their disadvantages.
  • Ruby is one of the best languages for metaprogramming, and Rails uses this capability well.

Scaffolding

You often create temporary code in the early stages of development to help get an application up quickly and see how major components work together. Rails automatically creates much of the scaffolding you’ll need.

Convention over configuration

  • Most Web development frameworks for .NET or Java forces to write pages of configuration code, instead Rails doesn’t need much configuration. The total configuration code can be reduced by a factor of five or more over similar Java frameworks just by following common conventions.
  • Naming your data model class with the same name as the corresponding database table
  • ‘id’ as the primary key name

Active Record framework

  • Saves objects to the database.
  • Discovers the columns in a database schema and automatically attaches them to domain objects using meta programming.

Action Pack

  • Views and controllers have a tight interaction, in rails they are combined in Action Pack
  • Action pack breaks a web request into view components and controller compoents

So an action usually involves a controller request to create, read, update, or delete (CRUD) some part of the model, followed by a view request to render a page

Rails implements the model-view-controller (MVC) architecture.

Model View Contoller (MVC)

The MVC design pattern separates the component parts of an application

MVC pattern allows rapid change and evolution of the user interface and controller separate from the data model

Model

Contains the data of the application

  • Transient
  • Stored (eg Database)

Enforces “business” rules of the application

  • Attributes
  • Work flow

View

  • Provides the user interface
  • Dynamic content rendered through templates
  • Three major types
    • Ruby code in erb (embedded ruby) templates
    • builder templates
    • rjs templates (for javascript, and thus ajax)

Controller

  • Perform the bulk of the heavy lifting
  • Handles web requests
  • Maintains session state
  • Performs caching
  • Manages helper modules

Ruby on Rails Objectives

  • Learn Ruby fundamentals
  • Learn how to install and configure Ruby and Rails
  • Explore the Model-view-Controller architecture for server-side applications
  • Learn to program the major components of Rails, including Active Record, Action Controller,       and Action View
  • Perform test-driven development of Rails applications

What Are The Prerequisites To Learn Ruby On Rails?

  • Basic knowledge of any programming language, Html and Javascript will be an added advantage.

Very nice material and course video available for your reference anytime. I repeatedly watched videos to learn required knowledge. Anyone would definitely miss out the physical presence inside the class while attending the course . I had lot of disturbance at home while class was going on and it didn't give me any seriousness about subject as I didn't see anyone looking at me if I am listening! This factor, someone is looking at me would definitely make me concentrate subject. Also 4 (four) hours of coaching online and very less interaction with people around makes very less impressive learning
