Node.js + Mongoose在本地运行，但不在Heroku上运行 [英] Node.js + Mongoose works locally, but not on Heroku

问题描述

这是我在Heroku上运行的node.js文件。它在本地完美工作，但是当我将它推到Heroku时，数据库集合不会创建，也不会引发错误。最终，我只是试图在Heroku上运行时实际创建连接。谢谢。

Here's my node.js file I'm running on Heroku. It works perfectly locally, but when I push it to Heroku, the database collection isn't created and no errors are thrown. Ultimately I'm just trying to get it to actually creating the connection while it's running on Heroku. Thanks.

var mongoose = require('mongoose'),
    db_url = process.env.MONGOHQ_URL || "mongodb://john:<mypasswordwashere>@staff.mongohq.com:10053/app3305538",
    db = mongoose.connect(db_url),
    Schema = mongoose.Schema;

//Mongoose DB Test
var MsgSchema = new Schema({
    date: {type: Date, default: Date.now},
    message: String
});
var MsgModel = db.model("messages", MsgSchema);
var Msg = new MsgModel();
Msg.message = "blurgh";
Msg.save();

推荐答案

您是否在heroku中指定节点版本？

Did you specify node version in heroku?
