5815:
1.424 albertel 5816: For this documentation:
5817:
5818: 'scanline' refers to the full line of characters
5819: from the file that we are parsing that represents one entire sheet
5820:
5821: 'bubble line' refers to the data
1.659 raeburn 5822: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5823:
5824:
1.659 raeburn 5825: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5826: into a course. When a user wants to grade, they select a
1.659 raeburn 5827: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5828: one of the predefined configurations for what each scanline looks
5829: like.
5830:
5831: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5832: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5833: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5834: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5835: invalid student/employee ID
1.424 albertel 5836:
5837: If the CODE option is used that determines the randomization of the
1.556 weissno 5838: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5839: username:domain.
5840:
5841: During the validation phase the instructor can choose to skip scanlines.
5842:
1.659 raeburn 5843: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5844:
5845: scantron_original_filename (unmodified original file)
5846: scantron_corrected_filename (file where the corrected information has replaced the original information)
5847: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5848:
5849: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5850: correction information that isn't representable in the bubblesheet
1.424 albertel 5851: file (see &scantron_getfile() for more information)
5852:
5853: After all scanlines are either valid, marked as valid or skipped, then
5854: foreach line foreach problem in the picked sequence, an ssi request is
5855: made that simulates a user submitting their selected letter(s) against
5856: the homework problem.

11676: =head1 NAME
11677:
11678: Apache::grades
11679:
11680: =head1 SYNOPSIS
11681:
11682: Handles the viewing of grades.
11683:
11684: This is part of the LearningOnline Network with CAPA project
11685: described at http://www.lon-capa.org.
11686:
11687: =head1 OVERVIEW
11688:
11689: Do an ssi with retries:
1.715 bisitz 11690: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11691: 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
11692: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11693:
11694: At least the logic that drives this has been pulled out into loncommon.
11695:
11696:
11697:
11698: ssi_with_retries - Does the server side include of a resource.
11699: if the ssi call returns an error we'll retry it up to
11700: the number of times requested by the caller.
1.715 bisitz 11701: If we still have a problem, no text is appended to the
1.531 jms 11702: output and we set some global variables.
11703: to indicate to the caller an SSI error occurred.
11704: All of this is supposed to deal with the issues described
1.715 bisitz 11705: in LON-CAPA BZ 5631 see:
1.531 jms 11706: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11707: by informing the user that this happened.
11708:
11709: Parameters:
11710: resource - The resource to include. This is passed directly, without
11711: interpretation to lonnet::ssi.
11712: form - The form hash parameters that guide the interpretation of the resource
11713:
11714: retries - Number of retries allowed before giving up completely.
11715: Returns:
11716: On success, returns the rendered resource identified by the resource parameter.
11717: Side Effects:
11718: The following global variables can be set:
11719: ssi_error - If an unrecoverable error occurred this becomes true.
11720: It is up to the caller to initialize this to false
11721: if desired.
11722: ssi_error_resource - If an unrecoverable error occurred, this is the value
11723: of the resource that could not be rendered by the ssi
11724: call.
11725: ssi_error_message - The error string fetched from the ssi response
11726: in the event of an error.

1.671 raeburn 11737: =head1 Routines to display previous version of a Task for a specific student
11738:
11739: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11740: can receive another opportunity. Access to tasks is slot-based. If a slot
11741: requires a proctor to check-in the student, a new version of the Task will
11742: be created when the student is checked in to the new opportunity.
11743:
11744: If a particular student has tried two or more versions of a particular task,
11745: the submission screen provides a user with vgr privileges (e.g., a Course
11746: Coordinator) the ability to display a previous version worked on by the
11747: student. By default, the current version is displayed. If a previous version
11748: has been selected for display, submission data are only shown that pertain
11749: to that particular version, and the interface to submit grades is not shown.

11780: current - student's current version
11781: displayed - student's version being displayed
11782: result - scalar containing HTML for web form used to switch to
11783: a different version (or a link to close window, if pop-up).
