Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

Single Responsibility Principle: a class should have only a single responsibility
Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

This guide explains the way to setup a production server using Capistrano.

# app/models/booking.rb
class Booking
  include RailsAdmin::Booking
end

# app/models/concerns/rails_admin/booking.rb

Getting Glyphicons from Bootstrap 3.0 in Rails: the easy way

What

Bootstrap 3.0 gives you access to the awesome icon set icon set by these dudes but it's not obvious for a Rails newbie like myself to get it all working together nicely

How

Download the bootstrap-glyphicons.css from here. Save that file to RAILS_ROOT/vendor/assets/stylesheet/bootstrap-glyphicons.css
Save all the font files in /dist/fonts from the Bootstrap 3.0 download to a new folder in your Rails app RAILS_ROOT/vendor/assets/fonts
Add this folder to the asset pipeline by appending config.assets.paths << Rails.root.join("vendor","assets", "fonts") to application.rb after the line that has class Application < Rails::Application.
In bootstrap-glyphicons.css modify the the `url
