我想先说一下我已经阅读了这里有关此问题的几篇文章。
我有一个节点/express/mongo 应用程序,其中包含以下内容:
app.js:
var express = require('express')
var bodyParser = require('body-parser')
var cors = require('cors')
var morgan = require('morgan')
var mongoose = require('mongoose')
var passport = require('passport')
var app = express()
// MongoDB Setup
var configDB = require('./config/database.js')
mongoose.connect(configDB.url)
app.use(morgan('combined'))
app.use(bodyParser.json())
// Check security with this
app.use(cors())
// load our routes and pass in our app and fully configured passport
require('./routes')(app)
app.listen(process.env.PORT || 8081)
console.log('We are up and running, captain.')
路线.js
const AuthenticationController = require('./controllers/AuthenticationController')
module.exports = (app) => {
app.post('/register', AuthenticationController.register)
}
我的 mongo 架构文件 Account.js:
const mongoose = require('mongoose')
const bcrypt = require('bcrypt-nodejs')
const Schema = mongoose.Schema
var accountSchema = new Schema({
email: String,
password: String,
likesPerDay: { type: Number, min: 0, max: 250 },
followPerDay: { type: Number, min: 0, max: 250 },
unfollowPerDay: { type: Number, min: 0, max: 250 },
commentsPerDay: { type: Number, min: 0, max: 250 },
comment: String,
hashtags: [String]
})
// methods ======================
// generating a hash. We hash password within user model, before it saves to DB.
accountSchema.methods.generateHash = function (password) {
return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null)
}
// checking if password is valid
accountSchema.methods.validPassword = function (password) {
return bcrypt.compareSync(password, this.local.password)
}
// create the model for users and expose it to our app
module.exports = mongoose.model('Account', accountSchema)
最后是我的控制器文件 AuthenticationController.js
const Account = require('../models/Account.js')
// var bodyParser = require('body-parser')
module.exports = {
register (req, res) {
Account.findOne({email: req.body.id}, function (err, account) {
if (err) {
console.log('Could not regster user')
throw err
}
if (account) {
console.log('account already exists')
} else {
Account.insertOne({email: req.body.email, password: req.body.password}, function (err, res) {
if (err) {
console.log('could not insert')
throw err
}
console.log('inserted account')
Account.close()
})
}
})
}
}
我的错误认证控制器当我打电话时归档Account.insertOne
功能。
我得到的错误是
类型错误:Account.insertOne 不是函数
现在,堆栈上的几篇文章建议我确保从我的模型类中导出模型,我正在这样做,这将解决这个问题。这很奇怪,因为findOne
方法似乎没问题,但是当我调用insertOne
我遇到一个问题。
我在这里错过了什么吗?
