mongoose mongo.js save array with array to collection

Question

I have this "schema" in mongoose, an array in my dictionary and have other embedded array,

I can save if no embedded object is present, how to save embedded objects?

var ReportSchema   = new Schema({
    appVersion: { type: String, required: true},
    osVersion: { type: String, required: true},
    deviceType: { type: String, required: true},
    userID: { type: String, required: true},
    sessionIDtimestamp: { type: String, required: true},

    eventItem : [new Schema ({
        eventType:{type :String},
        startTime:{type :String},
        endTime:{type :String},
        params:[new Schema ({
            val:{type :String}
        })]
    })]
});

on my router:

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   

        for (var i = req.body.events.length - 1; i >= 0; i--) {
            var requestStringa = util.inspect(req.body.events, {showHidden: false, depth: null});
            console.log("entro :"+requestStringa);      
        };

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

also i dont think that way to enumerate the array is nice?

edit the log of events

entro :[ { eventType: 'Account_Rated_Pressed',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] },
  { eventType: 'RateableDetail',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] } ]

how to save my embedded objects cheers

Since that's already an array, can't you just do report.eventItem = req.body.events;? — chridam

For saving embedded documents, just assign the array field eventItem the request object value as follows:

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   
        report.eventItem = req.body.events;

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

In the instance that req.body.event is an object not an array, you would then need to use the JavaScript push() method to push the object to the array. Say for example, if req.body.event has the structure

{ 
    eventType: 'Account_Rated_Pressed',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] 
}

you can then do

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   
        report.eventItem.push(req.body.event);

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

@MaKo No worries! I've also added some useful bits to the answer in the event that the req.body.event is an object not an array.
