*/
var EngineerScheduleSchema = new Schema({
title: { type: String, default: ''},
available: { type: Boolean, default: false },
sch_start: { type:Date, default: Date.now },
sch_end: { type:Date, default: Date.now }
});
export default mongoose.model('engineer_schedule', EngineerScheduleSchema);
// Main Model Mongoose Schema
schedule: [EngineerSchedule.schema]
//API Method
export function updateSchedulecalendar(req, res) {
var responseSchedule;
//Insert
return Engineer.findOneAndUpdate({ _id: req.params.id }, { $addToSet: { schedule: req.body } }, { new: true, upsert: true, setDefaultsOnInsert: true, runValidators: true }).exec()
.then((entity) => {
if (entity) {
responseSchedule = entity.schedule;
return EngineerEvents.emit(engineerEvents.updatedSchedule, req.user, entity);
}
else {
return res.status(404).end();
}
})
.then(()=> { return res.status(200).json(responseSchedule); })
.catch(handleError(res));
}

First, Since you are trying to send many schedules, your request body should look like:
[{
"title" : "test10",
"sch_start": "2017-04-3",
"sch_end":"2017-04-3"
},
{
"title" : "test11",
"sch_start": "2017-04-4",
"sch_end":"2017-04-4"
}]
Second, you should take a look at findOneAndUpdate documentation, cause it seems to me that you are sending two schedule objects (test10 and test11 ) to be updated on a single schedule specified by req.params.id. It does not make much sense.
If you are looking to update multiple schedules in a single request, maybe you should implement a bulk update. Take a look at bulk functionality, I would implement something like this:
export function updateSchedulecalendar(req, res) {
var responseSchedule;
var bulk = db.items.initializeUnorderedBulkOp();
// Iterate over every schedule sent by client
for(schedule in req.body) {
// Generate a new update statement for that specific document
bulk.find( { title: schedule.title } ).update( { $set: { sch_start: schedule.sch_start, ... } } );
}
// Execute all updates
bulk.execute().then(function() {
// Validation
});
}
