9. The Rails Way
10. Be DRY, don’t repeat yourself
11. Prefer convention over configuration
12. Be RESTful
13. REST uses operations of the HTTP protocol
14. REST GET PUT POST PATCH DELETE SOAP getUsers() getNewUsersSince() savePurchaseOrder() getUser() addUser() removeUser() updateUser() getLocation()
15. REST uses resources
16. http://myblog.com/posts/ GET PUT POST DELETE http://myblog.com/posts/1 GET PUT POST DELETE } }
17. Blog::Application.routes.draw do resources :posts end config/routes.rb
18. Use the MVC (Model View Controller) Pattern
20. class Post < ActiveRecord::Base attr_accessible :content, :name, :title has_many :commenters validates :title, presence: true end app/models/post.rb
21. <h1>Post <%= @post.title %> </h1> <%= @post.content %> <%= link_to 'Edit', edit_post_path(@post) %> <%= link_to 'Back', posts_path %> app/views/posts/show.rb
22. class PostsController < ApplicationController def new @post = Post.new end def create @post = Post.new(params[:post]) if @post.save redirect_to @post, notice: 'Post created!' else render action: :new end end end app/controllers/posts_controller.rb
24. Package your code for reuse
25. source 'https://rubygems.org' gem 'rails', '3.2.13' gem 'sqlite3' group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails' Gemfile
26. Be fast by default with the Asset Pipeline
28. app/assets assets from the current application lib/assets your own libraries, shared across applications vendor/assets third party assets(js plugins, css frameworks)
29. PRECOMPILE
31. CONCATENATE
