4827:
1.424 albertel 4828: For this documentation:
4829:
4830: 'scanline' refers to the full line of characters
4831: from the file that we are parsing that represents one entire sheet
4832:
4833: 'bubble line' refers to the data
4834: representing the line of bubbles that are on the physical bubble sheet
4835:
4836:
4837: The overall process is that a scanned in bubble sheet data is uploaded
4838: into a course. When a user wants to grade, they select a
4839: sequence/folder of resources, a file of bubble sheet info, and pick
4840: one of the predefined configurations for what each scanline looks
4841: like.
4842:
4843: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4844: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4845: because too light bubbling), 'double bubble' (each bubble line should
4846: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4847: invalid student/employee ID
1.424 albertel 4848:
4849: If the CODE option is used that determines the randomization of the
1.556 weissno 4850: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4851: username:domain.
4852:
4853: During the validation phase the instructor can choose to skip scanlines.
4854:
1.435 foxr 4855: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4856:
4857: scantron_original_filename (unmodified original file)
4858: scantron_corrected_filename (file where the corrected information has replaced the original information)
4859: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4860:
4861: Also there is a separate hash nohist_scantrondata that contains extra
4862: correction information that isn't representable in the bubble sheet
4863: file (see &scantron_getfile() for more information)
4864:
4865: After all scanlines are either valid, marked as valid or skipped, then
4866: foreach line foreach problem in the picked sequence, an ssi request is
4867: made that simulates a user submitting their selected letter(s) against
4868: the homework problem.

9507: =head1 NAME
9508:
9509: Apache::grades
9510:
9511: =head1 SYNOPSIS
9512:
9513: Handles the viewing of grades.
9514:
9515: This is part of the LearningOnline Network with CAPA project
9516: described at http://www.lon-capa.org.
9517:
9518: =head1 OVERVIEW
9519:
9520: Do an ssi with retries:
9521: While I'd love to factor out this with the vesrion in lonprintout,
9522: 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
9523: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9524:
9525: At least the logic that drives this has been pulled out into loncommon.
9526:
9527:
9528:
9529: ssi_with_retries - Does the server side include of a resource.
9530: if the ssi call returns an error we'll retry it up to
9531: the number of times requested by the caller.
9532: If we still have a proble, no text is appended to the
9533: output and we set some global variables.
9534: to indicate to the caller an SSI error occurred.
9535: All of this is supposed to deal with the issues described
9536: in LonCAPA BZ 5631 see:
9537: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9538: by informing the user that this happened.
9539:
9540: Parameters:
9541: resource - The resource to include. This is passed directly, without
9542: interpretation to lonnet::ssi.
9543: form - The form hash parameters that guide the interpretation of the resource
9544:
9545: retries - Number of retries allowed before giving up completely.
9546: Returns:
9547: On success, returns the rendered resource identified by the resource parameter.
9548: Side Effects:
9549: The following global variables can be set:
9550: ssi_error - If an unrecoverable error occurred this becomes true.
9551: It is up to the caller to initialize this to false
9552: if desired.
9553: ssi_error_resource - If an unrecoverable error occurred, this is the value
9554: of the resource that could not be rendered by the ssi
9555: call.
9556: ssi_error_message - The error string fetched from the ssi response
9557: in the event of an error.

9574: $r - Apache request object
9575: $i - number of the current scanline
9576: $scan_record - hash ref as returned from &scantron_parse_scanline()
9577: $scan_config - hash ref as returned from &get_scantron_config()

9582: 'duplicateID', 'incorrectID'
9583: $arg - extra information needed
9584: For errors:
9585: - duplicateID - paper number that this studentID was seen before on
9586: - duplicateCODE - array ref of the paper numbers this CODE was
9587: seen on before
9588: - incorrectCODE - current incorrect CODE
9589: - doublebubble - array ref of the bubble lines that have double
9590: bubble errors

9592: bubble errors

1.582 raeburn 9596: Arguments:
9597: $nav_error - Reference to scalar which is a flag to indicate a
9598: failure to retrieve a navmap object.
9599: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9600: calling routine should trap the error condition and display the warning
9601: found in &navmap_errormsg().
9602:
1.649 raeburn 9603: $scantron_config - Reference to bubblesheet format configuration hash.
9604:
1.531 jms 9605: Returns the maximum number of bubble lines that are expected to
9606: occur. Does this by walking the selected sequence rendering the

9612: $env{'form.scantron.first_bubble_line.n'} and
9613: $env{"form.scantron.sub_bubblelines.n"}
9614: which are the total number of bubble, lines, the number of bubble
9615: lines for response n and number of the first bubble line for response n,

9626: =item scantron_process_students() :
9627:
9628: Routine that does the actual grading of the bubble sheet information.
9629:
9630: The parsed scanline hash is added to %env
9631:
9632: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9633: foreach resource , with the form data of
9634:

9640: 'grade_symb' => symb of resource to grade
9641:
9642: This triggers a grading pass. The problem grading code takes care
