4824: 'bubble line' refers to the data

4826:
4827:
4828: The overall process is that a scanned in bubble sheet data is uploaded

4830: sequence/folder of resources, a file of bubble sheet info, and pick
4831: one of the predefined configurations for what each scanline looks
4832: like.
4833:
4834: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4835: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4836: because too light bubbling), 'double bubble' (each bubble line should
4837: have no more that one letter picked), invalid or duplicated CODE,

9439: =head1 NAME
9440:
9441: Apache::grades
9442:
9443: =head1 SYNOPSIS
9444:
9445: Handles the viewing of grades.
9446:
9447: This is part of the LearningOnline Network with CAPA project
9448: described at http://www.lon-capa.org.
9449:
9450: =head1 OVERVIEW
9451:
9452: Do an ssi with retries:
9453: While I'd love to factor out this with the vesrion in lonprintout,
9454: 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
9455: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9456:
9457: At least the logic that drives this has been pulled out into loncommon.
9458:
9459:
9460:
9461: ssi_with_retries - Does the server side include of a resource.
9462: if the ssi call returns an error we'll retry it up to
9463: the number of times requested by the caller.
9464: If we still have a proble, no text is appended to the
9465: output and we set some global variables.
9466: to indicate to the caller an SSI error occurred.
9467: All of this is supposed to deal with the issues described
9468: in LonCAPA BZ 5631 see:
9469: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9470: by informing the user that this happened.
9471:
9472: Parameters:
9473: resource - The resource to include. This is passed directly, without
9474: interpretation to lonnet::ssi.
9475: form - The form hash parameters that guide the interpretation of the resource
9476:
9477: retries - Number of retries allowed before giving up completely.
9478: Returns:
9479: On success, returns the rendered resource identified by the resource parameter.
9480: Side Effects:
9481: The following global variables can be set:
9482: ssi_error - If an unrecoverable error occurred this becomes true.
9483: It is up to the caller to initialize this to false
9484: if desired.
9485: ssi_error_resource - If an unrecoverable error occurred, this is the value
9486: of the resource that could not be rendered by the ssi
9487: call.
9488: ssi_error_message - The error string fetched from the ssi response
9489: in the event of an error.

9501:
9502: Builds the interface screen to interact with the operator to fix a
9503: specific error condition in a specific scanline
9504:
9505: Arguments:
9506: $r - Apache request object
9507: $i - number of the current scanline
9508: $scan_record - hash ref as returned from &scantron_parse_scanline()
9509: $scan_config - hash ref as returned from &get_scantron_config()
9510: $line - full contents of the current scanline
9511: $error - error condition, valid values are
9512: 'incorrectCODE', 'duplicateCODE',
9513: 'doublebubble', 'missingbubble',
9514: 'duplicateID', 'incorrectID'
9515: $arg - extra information needed
9516: For errors:
9517: - duplicateID - paper number that this studentID was seen before on
9518: - duplicateCODE - array ref of the paper numbers this CODE was
9519: seen on before
9520: - incorrectCODE - current incorrect CODE
9521: - doublebubble - array ref of the bubble lines that have double
9522: bubble errors
9523: - missingbubble - array ref of the bubble lines that have missing
9524: bubble errors
9525:
9526: =item scantron_get_maxbubble() :
9527:
1.582 raeburn 9528: Arguments:
9529: $nav_error - Reference to scalar which is a flag to indicate a
9530: failure to retrieve a navmap object.
9531: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9532: calling routine should trap the error condition and display the warning
9533: found in &navmap_errormsg().
9534:
1.531 jms 9535: Returns the maximum number of bubble lines that are expected to
9536: occur. Does this by walking the selected sequence rendering the
9537: resource and then checking &Apache::lonxml::get_problem_counter()
9538: for what the current value of the problem counter is.
9539:
9540: Caches the results to $env{'form.scantron_maxbubble'},
9541: $env{'form.scantron.bubble_lines.n'},
9542: $env{'form.scantron.first_bubble_line.n'} and
9543: $env{"form.scantron.sub_bubblelines.n"}
9544: which are the total number of bubble, lines, the number of bubble
9545: lines for response n and number of the first bubble line for response n,
9546: and a comma separated list of numbers of bubble lines for sub-questions
9547: (for optionresponse, matchresponse, and rankresponse items), for response n.
9548:
9549:
9550: =item scantron_validate_missingbubbles() :

9555:
9556: =item scantron_process_students() :
9557:
9558: Routine that does the actual grading of the bubble sheet information.
9559:
9560: The parsed scanline hash is added to %env
9561:
9562: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9563: foreach resource , with the form data of
9564:
9565: 'submitted' =>'scantron'
9566: 'grade_target' =>'grade',
9567: 'grade_username'=> username of student
9568: 'grade_domain' => domain of student
9569: 'grade_courseid'=> of course
9570: 'grade_symb' => symb of resource to grade
9571:
9572: This triggers a grading pass. The problem grading code takes care
9573: of converting the bubbled letter information (now in %env) into a
9574: valid submission.
9575:
9576: =item scantron_upload_scantron_data() :

9593: course.
9594:
9595: =item scantron_validate_ID() :
9596:
9597: Validates all scanlines in the selected file to not have any
