Evaluator Session Creation

Overview​

To facilitate the evaluator, evaluate the answer scripts within the bundles by creating evaluation sessions.

Feature Description​

Create Evaluation Session​

  • Purpose: The primary purpose of the API is to capture evaluator information at the beginning of each evaluation session.

  • Key Functions:

    • Image Capture: Capture the evaluator's image to record information each time they initiate the evaluation of a bundle.
    • Session Creation: Creating a new evaluation session for the evaluator.

  • Output: The API provides a session id upon successful creation of session.

Process Flow​

Development Steps​

  • Inputs: bundleId , file - captured image

  • Check the presence of an Evaluator Image file.

  • Validate the existence of the bundle with bundleId exists.

  • Validate if the bundle is assigned to the evaluator evaluatorId or not.

  • Create Evaluation Session:

    • If all checks pass, create a new evaluator session in the BundleEvaluationSession entity with provided bundleId , evaluatorId
    • Upload the image captured to the AWS S3
    • Link the uploaded image media object to the BundleEvaluationSession entity.

Schema​

src/domain/entities/bundle-evaluation-session.entity.ts

export class BundleEvaluationSession {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  bundleId: number;

  @Column()
  evaluatorId: number;

  image: MediaObject;

  @UpdateDateColumn()
  updatedAt: string;

  @CreateDateColumn()
  createdAt: string;

  @ManyToOne(() => Evaluator)
  evaluator: Evaluator;
}

Functions with individual test cases​

  • createEvaluationSession
    • creates an evaluation session and return id.

Dependent Modules​

  • BundleEvaluationSession Entity
