이전 단계의 SQLite 및 flask_sqlalchemy 구현을 확장합니다.

이전 테이블을 정의한 파일(제공된 예시를 따르는 경우 models.py)로 이동합니다. 파일 하단에 다음을 추가합니다.

# Database model to represent a student submission.
class Submission(db.Model):
    # The attachmentId is the unique identifier for the attachment.
    submission_id = db.Column(db.String(120), primary_key=True)

    # The unique identifier for the student's submission.
    attachment_id = db.Column(db.String(120), primary_key=True)

    # The student's response to the question prompt.
    student_response = db.Column(db.String(120))

새 Submission 클래스를 첨부파일 처리 경로와 함께 서버 파일로 가져옵니다.

사용자를 구분하려면 제출 함수를 사용 중지하고 대신 교사 보기에 정답을 표시하는 것이 좋습니다.
