5757:
1.424 albertel 5758: For this documentation:
5759:
5760: 'scanline' refers to the full line of characters
5761: from the file that we are parsing that represents one entire sheet
5762:
5763: 'bubble line' refers to the data
1.659 raeburn 5764: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5765:
5766:
1.659 raeburn 5767: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5768: into a course. When a user wants to grade, they select a
1.659 raeburn 5769: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5770: one of the predefined configurations for what each scanline looks
5771: like.
5772:
5773: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5774: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5775: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5776: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5777: invalid student/employee ID
1.424 albertel 5778:
5779: If the CODE option is used that determines the randomization of the
1.556 weissno 5780: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5781: username:domain.
5782:
5783: During the validation phase the instructor can choose to skip scanlines.
5784:
1.659 raeburn 5785: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5786:
5787: scantron_original_filename (unmodified original file)
5788: scantron_corrected_filename (file where the corrected information has replaced the original information)
5789: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5790:
5791: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5792: correction information that isn't representable in the bubblesheet
1.424 albertel 5793: file (see &scantron_getfile() for more information)
5794:
5795: After all scanlines are either valid, marked as valid or skipped, then
5796: foreach line foreach problem in the picked sequence, an ssi request is
5797: made that simulates a user submitting their selected letter(s) against
5798: the homework problem.

11575:
11576: =head1 SYNOPSIS
11577:
11578: Handles the viewing of grades.
11579:
11580: This is part of the LearningOnline Network with CAPA project
11581: described at http://www.lon-capa.org.
11582:
11583: =head1 OVERVIEW
11584:
11585: Do an ssi with retries:
1.715 bisitz 11586: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11587: 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
11588: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11589:
11590: At least the logic that drives this has been pulled out into loncommon.
11591:
11592:
11593:
11594: ssi_with_retries - Does the server side include of a resource.
11595: if the ssi call returns an error we'll retry it up to
11596: the number of times requested by the caller.
1.715 bisitz 11597: If we still have a problem, no text is appended to the
1.531 jms 11598: output and we set some global variables.
11599: to indicate to the caller an SSI error occurred.
11600: All of this is supposed to deal with the issues described
1.715 bisitz 11601: in LON-CAPA BZ 5631 see:
1.531 jms 11602: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11603: by informing the user that this happened.
11604:
11605: Parameters:
11606: resource - The resource to include. This is passed directly, without
11607: interpretation to lonnet::ssi.
11608: form - The form hash parameters that guide the interpretation of the resource
11609:
11610: retries - Number of retries allowed before giving up completely.
11611: Returns:
11612: On success, returns the rendered resource identified by the resource parameter.
11613: Side Effects:
11614: The following global variables can be set:
11615: ssi_error - If an unrecoverable error occurred this becomes true.
11616: It is up to the caller to initialize this to false
11617: if desired.
11618: ssi_error_resource - If an unrecoverable error occurred, this is the value
11619: of the resource that could not be rendered by the ssi
11620: call.
11621: ssi_error_message - The error string fetched from the ssi response
11622: in the event of an error.

1.671 raeburn 11633: =head1 Routines to display previous version of a Task for a specific student
11634:
11635: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11636: can receive another opportunity. Access to tasks is slot-based. If a slot
11637: requires a proctor to check-in the student, a new version of the Task will
11638: be created when the student is checked in to the new opportunity.
11639:
11640: If a particular student has tried two or more versions of a particular task,
11641: the submission screen provides a user with vgr privileges (e.g., a Course
11642: Coordinator) the ability to display a previous version worked on by the
11643: student. By default, the current version is displayed. If a previous version
11644: has been selected for display, submission data are only shown that pertain
11645: to that particular version, and the interface to submit grades is not shown.

11666: content in existing pop-up, or replaces page in main window.
11667:

11676: current - student's current version
11677: displayed - student's version being displayed
11678: result - scalar containing HTML for web form used to switch to
