Table that groups together all individual task submissions for a single exercise slise submission.
| Name | Type | Default | Nullable | Children | Parents | Comment |
|---|---|---|---|---|---|---|
| course_id | uuid | true | public.courses | Which course this submission belongs to. The field is here for making certain SQL queries easier, the same information is available from exercise_slide_submission.exercise_task.exercise.course_id. | ||
| course_instance_id | uuid | true | public.course_instances | Which course instance this submission was returned to. We need this field because each course instance has different submission lists. A submission to one course instance should not influence other submissions made later on to other course instance. This is useful, for example, if we have a course that never changes but it has a yearly run with a course variant for each year. Associating the submission with the course instance allows students to take the course even if they have tried a previous variant. | ||
| created_at | timestamp with time zone | now() | false | Timestamp when the record was created | ||
| deleted_at | timestamp with time zone | true | Timestamp when the record was deleted. If null, the record is not deleted. | |||
| exam_id | uuid | true | public.exams | The exam the submission is associated with. | ||
| exercise_id | uuid | false | public.exercises | Which exercise this submission belongs to. | ||
| exercise_slide_id | uuid | false | public.exercise_task_submissions | public.exercise_slides | Which exercise slide this submission belongs to. | |
| flag_count | integer | 0 | false | The number of times the submission has been flagged. | ||
| id | uuid | uuid_generate_v4() | false | public.exercise_task_submissions public.flagged_answers public.offered_answers_to_peer_review_temporary public.peer_or_self_review_submissions public.peer_review_queue_entries | A unique, stable identifier for the record. | |
| updated_at | timestamp with time zone | now() | false | Timestamp when the record was last updated. The field is updated automatically by the set_timestamp trigger. | ||
| user_id | uuid | false | public.users | The user that returned the submission | ||
| user_points_update_strategy | user_points_update_strategy | false | When we get results from a grading, how should we update the user’s points. See https://rage.github.io/secret-project-331/headless_lms_actix/models/gradings/enum.UserPointsUpdateStrategy.html. |
