未捕获的类型错误：mongoose.model 不是函数 - Jasmine

Question

无法在 node.js 上使用 jasmine-karma 运行测试。

我已经安装了 karma、jasmine、browserify、node 和 mongoose，我尝试运行我的测试但我收到错误“Uncaught TypeError: mongoose.model is not a function” 和“... user.js:10:0”。

UserModel = mongoose.model("Users", UserSchema, "users");

module.exports = UserModel;

Answer 1

您正在使用带有三个参数的 model 函数，这不是一个有效的声明。

试着写这个

user.js

'use strict';
var mongoose = require('mongoose');

var UserSchema = mongoose.Schema({
    email              : String,
    password           : String,
    isFacebookAccount  : Boolean
});

UserModel = mongoose.model("Users", UserSchema);

module.exports = UserModel;
