var mongoose = require(‘mongoose’);//引用mongoose模块 mongoose.connect(‘mongodb://localhost/db’);//引入一个数据库连接 var Schema = mongoose.Schema;

function Article(name,head,title,tags,zhengwen){ this.name = name; this.head = head; this.title = title; this.tags = tags; this.zhengwen = zhengwen; }

module.exports = Article;

var articleSchema = new Schema({ name:String, head:String, time:{ date:Date, year:Number, month:String, day:String, minute:String }, title:String, tags:[], zhengwen:String, comments:[], <span style=“background:red”>reprint_info:Schema.Types.Mixed,</span> pv:Number },{ collection:‘articles’ })

var articleModel = mongoose.model(‘article_Schema’,articleSchema);

//储存一篇文章和相关信息 Article.prototype.save = function(callback){ var date = new Date(); //储存各种时间格式，方便以后扩展 var time = { date:date, year:date.getFullYear(), month:date.getFullYear()+"-"+(date.getMonth()+1), day:date.getFullYear()+"-"+(date.getMonth()+1)+"-"+date.getDate(), minute:date.getFullYear()+"-"+(date.getMonth()+1)+"-"+date.getDate()+" “+date.getHours()+”:"+(date.getMinutes() < 10 ? ‘0’+date.getMinutes() : date.getMinutes()) } //要存入数据库的文档 var article = { name:this.name, head:this.head, time:time, title:this.title, tags:this.tags, zhengwen:this.zhengwen, comments:[], <span style=“background:red”>reprint_info:{},</span> pv:0 }

var newArticle = new articleModel(article);

newArticle.save(function(err, theArticle){
    if(err){
        return callback(err);
    }
    callback(null, theArticle);
})

};

其他字段都能顺利存入mongoDB，只有reprint_info不行，请教各位！
