使用猫鼬模型填充集合

Question

我想知道如何纠正错误，以填充在user.js文件中从app.js中声明的集合用户。

user.js文件

    var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    bcrypt = require(bcrypt),
    SALT_WORK_FACTOR = 10;

var UserSchema = new Schema({
    username: { 
        type: String, 
        required: true, 
        index: { unique: true } 
    }

});

module.exports = mongoose.model('User',UserSchema);

app.js文件

 var mongoose = require('mongoose');
require('./models/user');
mongoose.connect('mongodb://localhost/vip');

var models = require('mongoose-models');

var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {


    var User = models.require('User')();


    var fluffy = new User({ name: 'Eduardo' });


    fluffy.save(function (err, fluffy) {
      if (err) return console.error(err);
      console.log(User);
    });

    User.find(function (err, fluffy) {
      if (err) return console.error(err);
      console.log(User)
    })

});

MongoDB给我的输出错误

Answer 1

您的要求(Bcrypt)声明是不正确的。require需要一个字符串，所以您需要将它放入引号中。应该是bcrypt =require(“bcrypt”)
