Can't push values to mongoDB array

Hiii, I have a MEAN stack application that make use of a mongoose model defined as below:

appointment.js

var mongoose = require('mongoose');
module.exports = mongoose.model('Appointment', {
appt_date: String,
details: [ {
            appt_time: String,
            patient_id : String,
            patient_name : String,
            contact_no: String,
            doctor_name : String,
            purpose : String
          }
      ]
});

I want to generate a document like the following:

{
 appt_date: 13/13/2013,
 details: [
    {
        appt_time: 09:00 AM,
        patient_id: 2015/2016,
        patient_name: David John,
        contact_no: 8965741234,
        doctor_name: Albert ,
        purpose: Consultation,

    }
}

I can't generate a document when using the following Express JS code:

var Appointment = require('../../models/appointment');
var appointments = new Appointment ({ "appt_date" : req.body.date});
appointments.save();
Appointment.update({ appt_date: req.body.date},
{ 
  $push: {
           'details':  {    
                         appt_time:"09:00 AM",
                         patient_id:"2015/2016",
                         patient_name:"Wilfred",
                         contact_no:"8965741234",
                         doctor_name: "Albert",
                         purpose: "Consultation"
                       }
          }
 },
   {
      upsert:true
   });

After performing the above operations, the result that I get is as follows:

"_id": ObjectId('57b6eefd2b494e802ba146d8'),
"appt_date": "12/20/2014",
"details": [],
"__v": 0

I am not able to push any data to the "details" array. What I am in need is a single date entry (appt_date), multiple details (details array). Please help to solve this out.

Thank You.

You are updating document against the date and might be there are more than 1 app_date, this scenario will update multiple document ., you have to add multi : true object 

Appointment.update({ appt_date: req.body.date},
{ 
 $push: {
       'details':  {    
                     appt_time:"09:00 AM",
                     patient_id:"2015/2016",
                     patient_name:"Wilfred",
                     contact_no:"8965741234",
                     doctor_name: "Albert",
                     purpose: "Consultation"
                   }
      }
},
{multi: true},
 {
  upsert:true
 });

or you can update it by _id

Try with this code:

var Appointment = require('../../models/appointment');
var appointments = new Appointment();
appointments.appt_date = req.body.date;
appointment.details.push({appt_time:"09:00 AM",patient_id:"2015/2016", patient_name:"Wilfred",contact_no:"8965741234",doctor_name: "Albert",
purpose: "Consultation"});
appointments.save(function(err){
   if(!err)
      console.log("saved")
})

No need to do an update after save(), just use the push() method on the details key and then save. For example:

var Appointment = require('../../models/appointment');
var appointments = new Appointment ({ "appt_date" : req.body.date});
appointments.details.push({    
    appt_time: "09:00 AM",
    patient_id: "2015/2016",
    patient_name: "Wilfred",
    contact_no: "8965741234",
    doctor_name: "Albert",
    purpose: "Consultation"
});
appointments.save(function(err, appointment){
    if (err) handleErr(err);
    console.log(appointment);
});
