Attendance Model

Overview​

The attendance.model.js file defines the Mongoose schema for the attendance collection in the MongoDB database. It specifies the structure and properties of an attendance document.

Dependencies​

  • mongoose: The ODM library for MongoDB.
  • mongoose-delete: A Mongoose plugin for soft-deleting documents.

Schema Definition​

The attendanceSchema has the following fields:

  • user: A reference to the users collection, representing the user who is the subject of the attendance record. This field is required.
  • timeTable: A reference to the timeTables collection, representing the timetable entry for which the attendance is being recorded. This field is required.
  • timeOfAttendance: A Date representing the time the attendance was recorded. It defaults to the current date and time.
  • isLate: A boolean indicating whether the user was late. It defaults to false.

Collection Name​

The collection name is explicitly set to attendance.

Soft Deletes​

The mongoose-delete plugin is used to enable soft deletes for the Attendance model. This means that when a document is "deleted," it is not actually removed from the database. Instead, a deleted field is set to true, and a deletedAt field is added with the timestamp of the deletion.

Model​

The Attendance model is created from the schema and exported for use in other parts of the application.

Exports​

  • Attendance: The Mongoose model for the attendance collection.
