1.424 albertel 4842: because too light bubbling), 'double bubble' (each bubble line should

9444: =head1 NAME
9445:
9446: Apache::grades
9447:
9448: =head1 SYNOPSIS
9449:
9450: Handles the viewing of grades.
9451:
9452: This is part of the LearningOnline Network with CAPA project
9453: described at http://www.lon-capa.org.
9454:
9455: =head1 OVERVIEW
9456:
9457: Do an ssi with retries:
9458: While I'd love to factor out this with the vesrion in lonprintout,
9459: 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
9460: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9461:
9462: At least the logic that drives this has been pulled out into loncommon.
9463:
9464:
9465:
9466: ssi_with_retries - Does the server side include of a resource.
9467: if the ssi call returns an error we'll retry it up to
9468: the number of times requested by the caller.
9469: If we still have a proble, no text is appended to the
9470: output and we set some global variables.
9471: to indicate to the caller an SSI error occurred.
9472: All of this is supposed to deal with the issues described
9473: in LonCAPA BZ 5631 see:
9474: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9475: by informing the user that this happened.
9476:
9477: Parameters:
9478: resource - The resource to include. This is passed directly, without
9479: interpretation to lonnet::ssi.
9480: form - The form hash parameters that guide the interpretation of the resource
9481:
9482: retries - Number of retries allowed before giving up completely.
9483: Returns:
9484: On success, returns the rendered resource identified by the resource parameter.
9485: Side Effects:
9486: The following global variables can be set:
9487: ssi_error - If an unrecoverable error occurred this becomes true.
9488: It is up to the caller to initialize this to false
9489: if desired.
9490: ssi_error_resource - If an unrecoverable error occurred, this is the value
9491: of the resource that could not be rendered by the ssi
9492: call.
9493: ssi_error_message - The error string fetched from the ssi response
9494: in the event of an error.

9505: =item scantron_get_correction() :
9506:
9507: Builds the interface screen to interact with the operator to fix a
9508: specific error condition in a specific scanline
9509:
9510: Arguments:
9511: $r - Apache request object
9512: $i - number of the current scanline
9513: $scan_record - hash ref as returned from &scantron_parse_scanline()
9514: $scan_config - hash ref as returned from &get_scantron_config()
9515: $line - full contents of the current scanline
9516: $error - error condition, valid values are
9517: 'incorrectCODE', 'duplicateCODE',
9518: 'doublebubble', 'missingbubble',
9519: 'duplicateID', 'incorrectID'
9520: $arg - extra information needed
9521: For errors:
9522: - duplicateID - paper number that this studentID was seen before on
9523: - duplicateCODE - array ref of the paper numbers this CODE was
9524: seen on before
9525: - incorrectCODE - current incorrect CODE
9526: - doublebubble - array ref of the bubble lines that have double
9527: bubble errors
9528: - missingbubble - array ref of the bubble lines that have missing
9529: bubble errors
9530:
9531: =item scantron_get_maxbubble() :
9532:
1.582 raeburn 9533: Arguments:
9534: $nav_error - Reference to scalar which is a flag to indicate a
9535: failure to retrieve a navmap object.
9536: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9537: calling routine should trap the error condition and display the warning
9538: found in &navmap_errormsg().
9539:
1.531 jms 9540: Returns the maximum number of bubble lines that are expected to
9541: occur. Does this by walking the selected sequence rendering the
9542: resource and then checking &Apache::lonxml::get_problem_counter()
9543: for what the current value of the problem counter is.
9544:
9545: Caches the results to $env{'form.scantron_maxbubble'},
9546: $env{'form.scantron.bubble_lines.n'},
9547: $env{'form.scantron.first_bubble_line.n'} and
9548: $env{"form.scantron.sub_bubblelines.n"}
9549: which are the total number of bubble, lines, the number of bubble
9550: lines for response n and number of the first bubble line for response n,
9551: and a comma separated list of numbers of bubble lines for sub-questions
9552: (for optionresponse, matchresponse, and rankresponse items), for response n.

9560:
9561: =item scantron_process_students() :
9562:
9563: Routine that does the actual grading of the bubble sheet information.
9564:
9565: The parsed scanline hash is added to %env
9566:
9567: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9568: foreach resource , with the form data of
9569:
9570: 'submitted' =>'scantron'
9571: 'grade_target' =>'grade',
9572: 'grade_username'=> username of student
9573: 'grade_domain' => domain of student
9574: 'grade_courseid'=> of course
9575: 'grade_symb' => symb of resource to grade
9576:
9577: This triggers a grading pass. The problem grading code takes care
9578: of converting the bubbled letter information (now in %env) into a
9579: valid submission.
9580:

9598: course.
9599:
9600: =item scantron_validate_ID() :
