Can an Object be extracted from a nested array using a MongoDB Query?

In my mongoose schema, I have the following structure:

var AttendanceSchema = new mongoose.Schema({
  ownerId: mongoose.Schema.Types.ObjectId,
  companyId: mongoose.Schema.Types.ObjectId,
  months: [
    {
      currentSalary: {
        type: Number,
        default: 0
      },
      month: {
        type: Date,
      },
      salary: {
        type: Number,
        default: 0
      }
      days: [
        {
          manuallyUpdated: {
            type: Boolean,
            default: false
          },
          date: {
            type: Date,
          },
          perDaySalary: {
            type: Number,
            default: 0
          },
          status: {
            type: String,
          }
        }
      ]

    }
  ]
});

My goal is to extract a single object from the days array.

Note: The days array is nested within the months array. Although I have used $pull to remove that day object, I now need to pull and push it again (update the day).

Answer №1

If you have knowledge of the specific element within the days array that contains the information you require, then you can easily access it. The days array is made up of multiple elements, so pinpointing the correct one is crucial.
Let's say you need data from the first element in the array:

Attendance.findOne({_id: request.id}, function(err, foundAttendance){
console.log(foundAttendance.days[0].date);
}

You have the flexibility to adjust the number inside the square brackets to target any specific data you're looking for.
