node.js - How do I update more than one mongodb records at once? -

this question has answer here:

• how can update multiple documents in mongoose 2 answers

so creating basic todo app using express , mongodb @ backend, have task schema looks :

var taskschema = mongoose.schema({     task: string,     time:date,     done:boolean,     id:number    }); 

by default done not set, in frontend have unordered list , bunch of lines , each line has checkbox next , want when user selects list of tasks checkboxes , click on done button should go post request , mongodb should update tasks @ once , possible? approach correct?

suppose data in db:

[  {    _id: "1",    task: 'hello1',    time: '11-02-2015',    done: false  },  {    _id: "2",    task: 'hello2',    time: '11-02-2015',    done: false  },  {    _id: "3",    task: 'hello3',    time: '11-02-2015',    done: false  },  {    _id: "4",    task: 'hello4',    time: '11-02-2015',    done: false  },  {    _id: "5",    task: 'hello5',    time: '11-02-2015',    done: false  } ]; 

so sending selected tasks (let's call array) via post request on when done clicked.

array contain list of taskids this:

var tasksarr = [   "1", "2", "3", "4" ]; 

so doing in route function..

var bulk = taskschema.collection.initializeunorderedbulkop();  (var taskid in tasksarr) {    bulk.find({_id: taskid}).update({      '$set': {done: true}    }); }  bulk.execute(function(err, bulkres) {    console.log('modified:', bulkres.nmodified); }); 

hope helps.

cheers,
