|
| |
Stores away the result hash to a student's environment; |
| |
checks form.grade_ for specific values, otherwise stores |
| |
to the running user's environment. |
| |
|
| |
&check_correctness_changes() is called in two circumstances |
| |
in which the results hash is to be stored permanently, for |
| |
grading triggered by a student's submission, where feedback on |
| |
correctness is to be provided to the student. |
| |
|
| |
1. Immediately prior to storing the results hash |
| |
|
| |
To handle the case where a student's submission (and award) were |
| |
stored after history was retrieved in &initialize_storage(), e.g., |
| |
if a student submitted answers in quick succession (e.g., from |
| |
multiple tabs). &Apache::inputtags::hidealldata() is called for |
| |
any parts with out-of-order storage (i.e., correct then incorrect, |
| |
where awarded >= 1 when correct). |
| |
|
| |
2. Immediately after storing the results hash |
| |
|
| |
To handle the case where lond on the student's homeserver returns |
| |
delay:N -- where N is the number of transactions between the last |
| |
retrieved in &initialize_storage() and the last stored immediately |
| |
before permanent storage of the current transaction via |
| |
lond::store_handler(). &Apache::grades::makehidden() is called |
| |
for any parts with out-of-order storage (i.e., correct then incorrect, |
| |
where awarded >= 1 when correct). |
| |
|
| |
Will call &store_aggregates() to increment totals for attempts, |
| |
students, and corrects, if running user has student role. |
