rails new blog //创建应用
cd blog //进入应用目录 rails generate scaffold Post name
:string
title
:string
content
:text
rake db:migrate //创建数据表
rails server -p 888888
4. cd ..
5 rails new notebook
6 cd notebook
7 rails generate scaffold book name:string
rake db:migrate //创建数据表
在Mode目录 下创建一个 Post.rb
class Post < ActiveResource::Base
self.site = 'http://localhost:888888'
end
这样在controller里,可以调用post的方法了,比如Post.new或者Post.all
创建 welcomeController
$ rails generate controller welcome index
有些问题查看前一篇文章
打开 welcomecontroller.rb编辑
class WelcomeController < ApplicationController
def index
# notes = Note.find :all
notes = Note.all
puts "I see #{notes.size} note(s):"
notes.each do |note|
puts " #{note.date}: #{note.body}"
end
end
end
读者可以任意修改
rails server
http://localhost:3000/
终端下出现了
[2013-01-23 21:23:10] INFO WEBrick::HTTPServer#start: pid=4683 port=3000
I see 2 note(s):
2013-01-23: 你好,世界
