5817:
1.424 albertel 5818: For this documentation:
5819:
5820: 'scanline' refers to the full line of characters
5821: from the file that we are parsing that represents one entire sheet
5822:
5823: 'bubble line' refers to the data
1.659 raeburn 5824: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5825:
5826:
1.659 raeburn 5827: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5828: into a course. When a user wants to grade, they select a
1.659 raeburn 5829: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5830: one of the predefined configurations for what each scanline looks
5831: like.
5832:
5833: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5834: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5835: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5836: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5837: invalid student/employee ID
1.424 albertel 5838:
5839: If the CODE option is used that determines the randomization of the
1.556 weissno 5840: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5841: username:domain.
5842:
5843: During the validation phase the instructor can choose to skip scanlines.
5844:
1.659 raeburn 5845: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5846:
5847: scantron_original_filename (unmodified original file)
5848: scantron_corrected_filename (file where the corrected information has replaced the original information)
5849: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5850:
5851: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5852: correction information that isn't representable in the bubblesheet
1.424 albertel 5853: file (see &scantron_getfile() for more information)
5854:
5855: After all scanlines are either valid, marked as valid or skipped, then
5856: foreach line foreach problem in the picked sequence, an ssi request is
5857: made that simulates a user submitting their selected letter(s) against
5858: the homework problem.

11680: =head1 NAME
11681:
11682: Apache::grades
11683:
11684: =head1 SYNOPSIS
11685:
11686: Handles the viewing of grades.
11687:
11688: This is part of the LearningOnline Network with CAPA project
11689: described at http://www.lon-capa.org.
11690:
11691: =head1 OVERVIEW
11692:
11693: Do an ssi with retries:
1.715 bisitz 11694: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11695: 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
11696: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11697:
11698: At least the logic that drives this has been pulled out into loncommon.
11699:
11700:
11701:
11702: ssi_with_retries - Does the server side include of a resource.
11703: if the ssi call returns an error we'll retry it up to
11704: the number of times requested by the caller.
1.715 bisitz 11705: If we still have a problem, no text is appended to the
1.531 jms 11706: output and we set some global variables.
11707: to indicate to the caller an SSI error occurred.
11708: All of this is supposed to deal with the issues described
1.715 bisitz 11709: in LON-CAPA BZ 5631 see:
1.531 jms 11710: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11711: by informing the user that this happened.
11712:
11713: Parameters:
11714: resource - The resource to include. This is passed directly, without
11715: interpretation to lonnet::ssi.
11716: form - The form hash parameters that guide the interpretation of the resource
11717:
11718: retries - Number of retries allowed before giving up completely.
11719: Returns:
11720: On success, returns the rendered resource identified by the resource parameter.
11721: Side Effects:
11722: The following global variables can be set:
11723: ssi_error - If an unrecoverable error occurred this becomes true.
11724: It is up to the caller to initialize this to false
11725: if desired.
11726: ssi_error_resource - If an unrecoverable error occurred, this is the value
11727: of the resource that could not be rendered by the ssi
11728: call.
11729: ssi_error_message - The error string fetched from the ssi response
11730: in the event of an error.

11740:
1.671 raeburn 11741: =head1 Routines to display previous version of a Task for a specific student
11742:
11743: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11744: can receive another opportunity. Access to tasks is slot-based. If a slot
11745: requires a proctor to check-in the student, a new version of the Task will
11746: be created when the student is checked in to the new opportunity.
11747:
11748: If a particular student has tried two or more versions of a particular task,
11749: the submission screen provides a user with vgr privileges (e.g., a Course
11750: Coordinator) the ability to display a previous version worked on by the
11751: student. By default, the current version is displayed. If a previous version
11752: has been selected for display, submission data are only shown that pertain
11753: to that particular version, and the interface to submit grades is not shown.

11769:
11770: =item choose_task_version_form()
11771:

11774: content in existing pop-up, or replaces page in main window.
11775:

11784: current - student's current version
11785: displayed - student's version being displayed
11786: result - scalar containing HTML for web form used to switch to
11787: a different version (or a link to close window, if pop-up).
11788: js - javascript for processing selection in versions web form
