This document provides an overview of Ruby on Rails, including its history, what Rails is, the MVC framework, and how to set up a development environment using RVM and Bundler. Ruby was created in the mid-1990s and Rails was developed in 2005 as an open source web application framework built with Ruby. Rails emphasizes conventions over configuration, don't repeat yourself principles, and the model-view-controller pattern. RVM and Bundler are tools that help manage Ruby versions and gem dependencies to ensure a consistent development environment.

3. HISTORY
• Ruby is a dynamic, object-oriented, general-purpose
programming language.
• It was designed and developed in the mid-1990s
by Yukihiro Matsumoto in Japan.
• RUBY 0.95 in 21, December 1995

4. What is Rails
• Rails, is an open source web application
framework written in Ruby.
• By David Hansson on December 2005
• Rails is a full-stackframework that emphasizes the use of
well-known software engineering patterns and paradigms,
including
• convention over configuration (CoC)
• don't repeat yourself (DRY)
• model–view–controller (MVC)
• http://rubyonrails.org

6. RVM
• Ruby Version Manager
(RVM)
• RVM is a command-line tool
which allows you to easily
install, manage, and work
with multiple ruby
environments from
interpreters to sets of gems.

7. RVM
# Install and update rvm
curl -L https://get.rvm.io | bash -s head --autolibs=4
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
# Install ruby-2.1
rvm install 2.1.0 --autolibs=4
rvm use 2.1.0
rvm --default use 2.1.0
rvm gemset create real-estate
rvm gemset use real-estate
gem install rails -v '4.1.1'
bundle install
rvm use 2.1.0@real-estate
Create GemSet
Installing Ruby
Using Bundler

8. Bundler
• Bundler provides a consistent environment for Ruby
projects by tracking and installing the exact gems and
versions that are needed.
• Bundler is an exit from dependency hell, and ensures that
the gems you need are present in development, staging,
and production. Starting work on a project is as simple
as bundle install.
