5604:
5605: 'scanline' refers to the full line of characters
5606: from the file that we are parsing that represents one entire sheet
5607:
5608: 'bubble line' refers to the data
1.659 raeburn 5609: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5610:
5611:
1.659 raeburn 5612: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5613: into a course. When a user wants to grade, they select a
1.659 raeburn 5614: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5615: one of the predefined configurations for what each scanline looks
5616: like.
5617:
5618: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5619: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5620: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5621: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5622: invalid student/employee ID
1.424 albertel 5623:
5624: If the CODE option is used that determines the randomization of the
1.556 weissno 5625: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5626: username:domain.
5627:
5628: During the validation phase the instructor can choose to skip scanlines.
5629:
1.659 raeburn 5630: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5631:
5632: scantron_original_filename (unmodified original file)
5633: scantron_corrected_filename (file where the corrected information has replaced the original information)
5634: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5635:
5636: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5637: correction information that isn't representable in the bubblesheet
1.424 albertel 5638: file (see &scantron_getfile() for more information)
5639:
5640: After all scanlines are either valid, marked as valid or skipped, then
5641: foreach line foreach problem in the picked sequence, an ssi request is
5642: made that simulates a user submitting their selected letter(s) against
5643: the homework problem.

11388:
11389: =head1 SYNOPSIS
11390:
11391: Handles the viewing of grades.
11392:
11393: This is part of the LearningOnline Network with CAPA project
11394: described at http://www.lon-capa.org.
11395:
11396: =head1 OVERVIEW
11397:
11398: Do an ssi with retries:
1.715 bisitz 11399: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11400: 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
11401: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11402:
11403: At least the logic that drives this has been pulled out into loncommon.
11404:
11405:
11406:
11407: ssi_with_retries - Does the server side include of a resource.
11408: if the ssi call returns an error we'll retry it up to
11409: the number of times requested by the caller.
1.715 bisitz 11410: If we still have a problem, no text is appended to the
1.531 jms 11411: output and we set some global variables.
11412: to indicate to the caller an SSI error occurred.
11413: All of this is supposed to deal with the issues described
1.715 bisitz 11414: in LON-CAPA BZ 5631 see:
1.531 jms 11415: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11416: by informing the user that this happened.
11417:
11418: Parameters:
11419: resource - The resource to include. This is passed directly, without
11420: interpretation to lonnet::ssi.
11421: form - The form hash parameters that guide the interpretation of the resource
11422:
11423: retries - Number of retries allowed before giving up completely.
11424: Returns:
11425: On success, returns the rendered resource identified by the resource parameter.
11426: Side Effects:
11427: The following global variables can be set:
11428: ssi_error - If an unrecoverable error occurred this becomes true.
11429: It is up to the caller to initialize this to false
11430: if desired.
11431: ssi_error_resource - If an unrecoverable error occurred, this is the value
11432: of the resource that could not be rendered by the ssi
11433: call.
11434: ssi_error_message - The error string fetched from the ssi response
11435: in the event of an error.

1.671 raeburn 11446: =head1 Routines to display previous version of a Task for a specific student
11447:
11448: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11449: can receive another opportunity. Access to tasks is slot-based. If a slot
11450: requires a proctor to check-in the student, a new version of the Task will
11451: be created when the student is checked in to the new opportunity.
11452:
11453: If a particular student has tried two or more versions of a particular task,
11454: the submission screen provides a user with vgr privileges (e.g., a Course
11455: Coordinator) the ability to display a previous version worked on by the
11456: student. By default, the current version is displayed. If a previous version
11457: has been selected for display, submission data are only shown that pertain
11458: to that particular version, and the interface to submit grades is not shown.
