我想用mongoose返回一个dbs系列的列表.我遵循这里的指示,但是http://grokbase.com/t/gg/mongoose-orm/122xxxr7qy/mongoose-get-a-list-of-all-collections.这是我的代码
var mongoose = require('mongoose');
//if (mongoose.connection.readyState == 0){//checks if already connected to the database
console.log("creating connection to the database");
var Config = require('../configs/config');
var config = new Config();
config = config.getConfig().db.dev;
if (mongoose.connection.readyState = 0 ) {
mongoose.connect("mongodb://austin:password1@paulo.mongohq.com:10023/test1");
console.log('mongoose readyState is ' + mongoose.connection.readyState);
}
var collection;
mongoose.connection.on('open', function (ref) {
console.log('Connected to mongo server.');
});
//trying to get collection names
mongoose.connection.db.collectionNames(function (err, names) {
console.log(names); // [{ name: 'dbname.myCollection' }]
module.exports.Collection = names;
});
唯一的问题是名称返回为未定义.那么,仅仅使用香草mongoose 就可以返回Collection 列表吗?
