Time Table Model

Overview​

The timeTable.model.js file defines the Mongoose schema for the timeTables collection in the MongoDB database. It specifies the structure and properties of a timetable document, representing a scheduled class or event.

Dependencies​

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

Schema Definition​

The timeTableSchema has the following fields:

  • subject: A reference to the subjects collection, indicating the subject being taught. This field is required.
  • startTime: A Date representing the start time of the class/event. This field is required.
  • endTime: A Date representing the end time of the class/event. This field is required.
  • classroom: A reference to the classrooms collection, indicating where the class/event takes place. This field is required.
  • teacher: A reference to the users collection, indicating the teacher assigned to the class/event. This field is required.
  • teacherEntryTime: An optional Date field to record when the teacher entered the classroom.
  • teacherExitTime: An optional Date field to record when the teacher exited the classroom.

Timestamps​

The schema is configured with timestamps: true, which automatically adds createdAt and updatedAt fields to each document.

Collection Name​

The collection name is explicitly set to timeTables.

Soft Deletes​

The mongoose-delete plugin is used to enable soft deletes for the timeTable 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 timeTable model is created from the schema and exported for use in other parts of the application.

Exports​
