12623:
12624: =head1 SYNOPSIS
12625:
12626: Handles the viewing of grades.
12627:
12628: This is part of the LearningOnline Network with CAPA project
12629: described at http://www.lon-capa.org.
12630:
12631: =head1 OVERVIEW
12632:
12633: Do an ssi with retries:
1.715 bisitz 12634: While I'd love to factor out this with the version in lonprintout,
1.531 jms 12635: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
12636: I'm not quite ready to invent (e.g. an ssi_with_retry object).
12637:
12638: At least the logic that drives this has been pulled out into loncommon.
12639:
12640:
12641:
12642: ssi_with_retries - Does the server side include of a resource.
12643: if the ssi call returns an error we'll retry it up to
12644: the number of times requested by the caller.
1.715 bisitz 12645: If we still have a problem, no text is appended to the
1.531 jms 12646: output and we set some global variables.
12647: to indicate to the caller an SSI error occurred.
12648: All of this is supposed to deal with the issues described
1.715 bisitz 12649: in LON-CAPA BZ 5631 see:
1.531 jms 12650: http://bugs.lon-capa.org/show_bug.cgi?id=5631
12651: by informing the user that this happened.
12652:
12653: Parameters:
12654: resource - The resource to include. This is passed directly, without
12655: interpretation to lonnet::ssi.
12656: form - The form hash parameters that guide the interpretation of the resource
12657:
12658: retries - Number of retries allowed before giving up completely.
12659: Returns:
12660: On success, returns the rendered resource identified by the resource parameter.
12661: Side Effects:
12662: The following global variables can be set:
12663: ssi_error - If an unrecoverable error occurred this becomes true.
12664: It is up to the caller to initialize this to false
12665: if desired.
12666: ssi_error_resource - If an unrecoverable error occurred, this is the value
12667: of the resource that could not be rendered by the ssi
12668: call.
12669: ssi_error_message - The error string fetched from the ssi response
12670: in the event of an error.

1.671 raeburn 12681: =head1 Routines to display previous version of a Task for a specific student
12682:
12683: Tasks are graded pass/fail. Students who have yet to pass a particular Task
12684: can receive another opportunity. Access to tasks is slot-based. If a slot
12685: requires a proctor to check-in the student, a new version of the Task will
12686: be created when the student is checked in to the new opportunity.
12687:
12688: If a particular student has tried two or more versions of a particular task,
12689: the submission screen provides a user with vgr privileges (e.g., a Course
12690: Coordinator) the ability to display a previous version worked on by the
12691: student. By default, the current version is displayed. If a previous version
12692: has been selected for display, submission data are only shown that pertain
12693: to that particular version, and the interface to submit grades is not shown.
