Module exercise_task_submission_files 

Which host-stored files a task submission was made from.

The exercise service’s answer is an opaque blob, so the host cannot recover a submission’s files by reading it. Recording the association at submit time is what lets the host serve those files back without interpreting any plugin’s answer shape.

Structs

ExerciseAnswerFile

One file of one file-typed answer to an exercise, for the teacher bulk download.

SubmissionFile

One file of a task submission, joined with the file_uploads row it points at.

Functions

delete_by_task_submission_and_file_upload_ids

Soft-deletes one submission-to-file link, leaving both the submission and the upload alone.

exercise_has_answer_files

Whether the exercise has at least one file-typed answer whose files still exist.

get_answer_files_by_exercise_id

Every file of every file-typed answer to the exercise, ordered by user, then submission time, then the order the client sent the files in.

get_by_task_submission_ids

The files of the given task submissions, ordered by submission and then by the order the client sent them in. Soft-deleted files are omitted, so a reaped upload simply disappears from the listing.

get_positions_by_task_submission_id

The files a submission recorded, paired with their positions, in stored order.

insert_many

Records the files a task submission was made from, in the order the client sent them.
