javascript - 无法写入mongodb

Question

我正在尝试使用 node.js 填充我的 mongo db。但我收到一个 TypeError 说

' 对象 # 没有应用方法

.

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
console.log('Running mongoose version %s:', mongoose.version);



var userSchema = Schema({
    userName: String,
    fullName: String,
    email: String
});
var articleSchema = Schema({
    name: String,
    content_date: Date,
    content: String,
    author: String
});

var User = mongoose.model('User', userSchema);
var Article = mongoose.model('Article', articleSchema);

var createData = function () {
    User.create({userName: 'mcslater', fullName: 'Ray Slater', email: 'r.slater@nomail'}, function (err, user) {
        Article.create({
                "name": "NEW YORK MAGAZINE",
                "content": "Heaven, with hangers. <a href='http://nymag.com/fashion/08/fall/49258/index4.html' target='_blank'>New York Magazine</a> declares the MKG Wardrobe 'gorgeous' in the Fall Fashion '08 issue.",

            {

            })
    })
};


mongoose.connect('localhost','news',function(err){
    if(err) throw err;
    createData();
});

我认为您忘记了“新”关键字：

var userSchema = new Schema({ // <-- new 
    userName: String,
    fullName: String,
    email: String
});

var articleSchema = new Schema({ // <-- new
    name: String,
    content_date: Date,
    content: String,
    author: String
});
