Classroom Model

Overview​

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

Dependencies​

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

Schema Definition​

The classroomSchema has the following fields:

  • roomNumber: A number representing the room number of the classroom. This field is required.
  • capacity: A number representing the capacity of the classroom. This field is required.
  • isLab: A boolean indicating whether the classroom is a lab. It defaults to false.
  • scanner: A reference to the scanners collection, representing the scanner associated with the classroom. This field is required.

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 classrooms.

Soft Deletes​

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

Exports​

  • Classroom: The Mongoose model for the classrooms collection.
