資料層:Mongoose NTU CCSP 2012Fall
目標 • 安裝mongodb • 使用mongo shell • 簡易CRUD
環境 • Windows 7 • Sublime Text 2 • Node.js
0.8.x • Express.js 3.0 • Mongoose.js
MONGODB INSTALL
Step 0: 下載mongodb
Step 0: 下載mongodb
Step 1: 解壓縮移動到C 並命名為mongodb
Step 2: 設定環境
Step 3: 啟動mongod
Step 4: 進入mongo shell
MONGO SHELL
MongoDB • 是一種NoSQL • 不需要資料綱要(Schema-Free) • 允許巢狀資料 • 沒有JOIN 沒有TRANS
• 簡單說就是一個存放JSON的資料庫 所以才 會跟Node.js很合
MongoDB練習 • http://try.mongodb.org/
FIRST LOOK OF MONGOOSE
Step -1: 請先安裝mongoose npm install mongoose -g
Step 0: 產生綱要 1. 產生schema 2. 產生model instance.save(fn(err){}) 儲存 Model.find()
搜尋
Step 0: 產生綱要
Step 1: 更新與刪除 • Model.remove() 刪除所有文件 • instance.remove() 刪除一個文件
Step 2: 綱要進階 • 常用type String, Number, Date, ObjectId •
Array用法 • Embed Docs => Array嵌入物件
CRUD BY EXPRESS+MONGOOSE
Step 0: 建立express專案
Step 1: 修改package.json
Step 2: 安裝套件
Step3: 編輯models/User.js
Step 3: 編輯 app.js • mongoose.connect和 mongoose.createConnection是不 同的 • 前者是模組等級
後者是獨立連線 • 沒有指明連線的model會嘗試使用 並等待模組等級連線建立
Step 4: Create • 編輯route/user.js • 注意callback的例外
Step 4: Create • 編輯view/index.ejs
Step 4.5: 來試試看吧
Step 5: Read • Read包含兩種 • 讀取集合 • 讀取單一物件
Step 6: Update
Step 6: Update • Callback hell很痛苦 • 銀幕在寬都不夠
Step 8: step.js解決cb hell • 解決callback hell • Err可以很帥氣的throw
遺珠之憾 • Population http://mongoosejs.com/docs/populate.html • Middleware http://mongoosejs.com/docs/middleware.html • Advanced Query
http://mongoosejs.com/docs/queries.html • SQL to Mongo mapping http://www.mongodb.org/display/DOCS/SQL+to+Mongo+Map ping+Chart • Step.js https://github.com/creationix/step
