我想记录每次计算,但是cal.save()没有在mongodb中注册数据对象。目前它只是阻止我的猫鼬模块):任何善良的灵魂都愿意看我的简单代码。
# Import library files
restify = require 'restify'
mongoose = require 'mongoose'
# Create schema for recording calculations
calculationSchema = new mongoose.Schema
action: String
firstNumber: Number
secondNumber: Number
timeStamp:
type: Date
default: Date.now
Calculation = mongoose.model 'calculation', calculationSchema
# Start and verify mongodb connection
mongoose.connect 'mongodb://localhost/test'
db = mongoose.connection
db.on 'error', console.error.bind console, 'connection error:'
db.once 'open', ->
console.log "Successfully connected to MongoDB"
# Create API server to listen to requests
server = restify.createServer()
# Create GET API that capture all params in the urls
server.get '/calculate/:action/:firstNum/:secondNum', (req, res, next) ->
action = req.params.action
firstNum = parseFloat req.params.firstNum
secondNum = parseFloat req.params.secondNum
# Create Calculation object
cal = new Calculation
action: action
firstNumber: firstNum
secondNumber: secondNum
cal.save (err, cal) ->
# Handle Errors
if err then console.log 'Erorr in saving calculation'
res.send 200
另外,为了检查它是否已保存,我转到终端并键入mongo,然后输入db.calculation.find()但没有出现任何内容:
答案 0 :(得分:2)
Mongoose将您的小写型号名称复数以确定要使用的集合。所以你需要查看calculations
集合。
db.calculations.find()
