My node.js application has one MongoDB (db1) which has user details. Each user has different database (MongoDB). So I maintain all the database information in db1.
Here my question is based on user: I need to open user database connection at runtime and perform some operation in user database.
How can I do so?
My app.js is:
var mongoose = require("mongoose"); var conn = mongoose.createConnection('mongodb://localhost/testA'); var conn2 = mongoose.createConnection('mongodb://localhost/testB'); var modelConfig = require('./api/model/action.model'); modelConfig.dynamicModel(conn, function (model) { model.create({name: 'testA', description: 'description A'}, function (err, data) { console.log("data: " + data); console.log("err: " + err); }); }); modelConfig.dynamicModel(conn2, function (model) { model.create({name: 'testB', description: 'description B'}, function (err, data) { console.log("data: " + data); console.log("err: " + err); }); }); My model file look like below:
'use strict'; var restful = require("node-restful"); var mongoose = restful.mongoose; var modelConfig = require('../schema/action.schema'); var actionSchema = new mongoose.Schema(modelConfig.schema); module.exports.dynamicModel = function(con,cb){ var action = con.model(modelConfig.title, actionSchema); cb(action); }; My schema file look like bellow.
'use strict'; var restful = require("node-restful"); var mongoose = restful.mongoose; module.exports = { title: "action", //mongo db collection name schema: { name: { type: String, required: true, unique: true}, description: { type: String, required: false} } } Install node-restful, mongoose and mongodb package and node app.
It will save the recodes in testA and testB database.
