node.js - switching database with mongoose -


hi there way switch database mongoose? thought that:

mongoose.disconnect(); mongoose.connect('localhost',db);

but not work receive error:

error: trying open unclosed connection.

i not know if because asynchronous

it asynchronous. if pass callback function disconnect , try connect next database in callback, work.

ex.

var mongoose = require('mongoose')  mongoose.connect('mongodb://localhost/test1', function() {   console.log('connected test 1')   mongoose.disconnect(connecttotest2) })  function connecttotest2() {   mongoose.connect('mongodb://localhost/test2', function() {     console.log('connected test 2')     process.exit()   }) }
