首先必须安装Ruby on Rails。
新建一个叫做**myforum**的Rails app（以下所有命令在iTerm中输入）：
rails new myforum
生成 MyForum 的model
rails generate scaffold MyForm title:string descrption:text
把变更移到database
rake db:migrate
编写seeds.rb文件，批量写入数据
打开db/seeds.rb文件，写入：
# db/seeds.rb
MyForum.create!(title: 'grocery shopping', descrption: 'pickles, eggs, red onion')
MyForum.create!(title: 'wash the car')
MyForum.create!(title: 'register kids for school', descrption: 'Register Kira for Ruby Junior High and Caleb for Rails High School')
Todo.create!(title: 'check engine light', descrption: 'The check engine light is on in the Tacoma')
Todo.create!(title: 'dog groomers', descrption: 'Take Pinky and Redford to the groomers on Wednesday the 23rd')
在ITerm里执行命令
rake db:seed
设置主页路径
在 config/routes.rb 文件里, 加入 root 'myforums#index'
最后，在server上预览,在iTerm中输入：
rails s
