我的应用程序设置为猫鼬模型,控制器和路由在不同的文件中.

但是用mongoose实现它,我只是无法弄明白.

所以请有人告诉我它是如何使用的.请看下面.

//express controller Article.js


var mongoose = require('mongoose'),errorHandler = require('./errors'),Article = mongoose.model('Article');

exports.list = function(req,res) {
Article.find().sort('-created').populate('user','displayName').exec(function(err,articles) {
      if (err) {
          return res.status(400).send({
            message: errorHandler.getErrorMessage(err)
          });
      } else {
          res.jsonp(articles);
      }
  });
};

//猫鼬模型

/**
 * Module dependencies.
 */
 var mongoose = require('mongoose'),Schema = mongoose.Schema;

 /**
 * Article Schema
 */
 var ArticleSchema = new Schema({
    created: {
        type: Date,default: Date.now
    },title: {
        type: String,default: '',trim: true,required: 'Title cannot be blank'
    },content: {
        type: String,trim: true
    },user: {
        type: Schema.ObjectId,ref: 'User'
    }
});

mongoose.model('Article',ArticleSchema);

所以,如果我想使用Bluebird promise库,我将如何更改export.list

提前致谢.

一些问题,

我在哪里可以在猫鼬模型上调用promisify？
例如Article = mongoose.model(‘Article’);
喜欢thisArticle = Promise.promisifyAll(require(‘Article’));
要么
像这样

var Article = mongoose.model('Article');
  Article = Promise.promisifyAll(Article);

解决方法

var Article = mongoose.model('Article',ArticleSchema);
Promise.promisifyAll(Article);
Promise.promisifyAll(Article.prototype);

exports.Article = Article;
//Replace Article with the name of your Model.

exports.create = function(req,res) {
    var article = new Article(req.body);
    article.user = req.user;

    article.saveAsync().then(function(){
        res.jsonp(article);
    }).catch(function (e){
        return res.status(400).send({
            message: errorHandler.getErrorMessage(e)
        });
    });
  };
