Assignment has self assessments or due date has passed

Error message

Assignment has self assessments or due date has passed

What it means

SetRubricSelfAssessment raises this GraphQL::ExecutionError when assignment.can_update_rubric_self_assessment? returns false (app/graphql/mutations/set_rubric_self_assessment.rb:54). This means the assignment already has student self assessments recorded, or its due date has passed — both of which make the setting no longer editable.

Solutions

1. Toggle self assessment only before the assignment due date and before any self assessments exist.
2. Check assignment.can_update_rubric_self_assessment? / due date client-side before calling the mutation.
3. Disable or lock the UI toggle once due date passes or submissions exist.
4. Contact an admin or use course-level tooling if a deadline extension is appropriate, then retry.

Example fix

// before
await client.mutate({ mutation: SET_SELF_ASSESSMENT, variables: { assignmentId } })
// after
if (assignment.canUpdateRubricSelfAssessment) {
  await client.mutate({ mutation: SET_SELF_ASSESSMENT, variables: { assignmentId } })
}

if (!assignment.canUpdateRubricSelfAssessment) throw new SkipMutation('self assessments exist or due date passed')

try { await mutate(...) } catch (e) { if (e.message.includes('due date has passed')) showLockedNotice(); else throw e; }

When it happens

Trigger: Invoking the setRubricSelfAssessment mutation on an assignment that already has rubric self assessments submitted by students, or whose due date is in the past, while all earlier validation (permissions, group/quiz/discussion type) passes.

Common situations: Teacher tries to disable self assessment after students already submitted one; user attempts the change after the semester/due date ended; importing or copying settings from a template assignment that already has self assessments.
