pub async fn set_grade_for_testing(
conn: &mut PgConnection,
id: Uuid,
grade: Option<i32>,
passed: Option<bool>,
) -> ModelResult<()>Expand description
Rewrites a completion’s grade in place, so a test can regrade one.
Exists only for test setup, behind the mock study registry’s control surface: a teacher regrade goes through the manual completion flow, which writes a new completion row rather than editing this one, and there is no product path that edits a completion’s grade.
