4782:
1.424 albertel 4783: For this documentation:
4784:
4785: 'scanline' refers to the full line of characters
4786: from the file that we are parsing that represents one entire sheet
4787:
4788: 'bubble line' refers to the data
4789: representing the line of bubbles that are on the physical bubble sheet
4790:
4791:
4792: The overall process is that a scanned in bubble sheet data is uploaded
4793: into a course. When a user wants to grade, they select a
4794: sequence/folder of resources, a file of bubble sheet info, and pick
4795: one of the predefined configurations for what each scanline looks
4796: like.
4797:
4798: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4799: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4800: because too light bubbling), 'double bubble' (each bubble line should
4801: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4802: invalid student/employee ID
1.424 albertel 4803:
4804: If the CODE option is used that determines the randomization of the
1.556 weissno 4805: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4806: username:domain.
4807:
4808: During the validation phase the instructor can choose to skip scanlines.
4809:
1.435 foxr 4810: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4811:
4812: scantron_original_filename (unmodified original file)
4813: scantron_corrected_filename (file where the corrected information has replaced the original information)
4814: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4815:
4816: Also there is a separate hash nohist_scantrondata that contains extra
4817: correction information that isn't representable in the bubble sheet
4818: file (see &scantron_getfile() for more information)
4819:
4820: After all scanlines are either valid, marked as valid or skipped, then
4821: foreach line foreach problem in the picked sequence, an ssi request is
4822: made that simulates a user submitting their selected letter(s) against
4823: the homework problem.

9386: =head1 NAME
9387:
9388: Apache::grades
9389:
9390: =head1 SYNOPSIS
9391:
9392: Handles the viewing of grades.
9393:
9394: This is part of the LearningOnline Network with CAPA project
9395: described at http://www.lon-capa.org.
9396:
9397: =head1 OVERVIEW
9398:
9399: Do an ssi with retries:
9400: While I'd love to factor out this with the vesrion in lonprintout,
9401: 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
9402: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9403:
9404: At least the logic that drives this has been pulled out into loncommon.
9405:
9406:
9407:
9408: ssi_with_retries - Does the server side include of a resource.
9409: if the ssi call returns an error we'll retry it up to
9410: the number of times requested by the caller.
9411: If we still have a proble, no text is appended to the
9412: output and we set some global variables.
9413: to indicate to the caller an SSI error occurred.
9414: All of this is supposed to deal with the issues described
9415: in LonCAPA BZ 5631 see:
9416: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9417: by informing the user that this happened.
9418:
9419: Parameters:
9420: resource - The resource to include. This is passed directly, without
9421: interpretation to lonnet::ssi.
9422: form - The form hash parameters that guide the interpretation of the resource
9423:
9424: retries - Number of retries allowed before giving up completely.
9425: Returns:
9426: On success, returns the rendered resource identified by the resource parameter.
9427: Side Effects:
9428: The following global variables can be set:
9429: ssi_error - If an unrecoverable error occurred this becomes true.
9430: It is up to the caller to initialize this to false
9431: if desired.
9432: ssi_error_resource - If an unrecoverable error occurred, this is the value
9433: of the resource that could not be rendered by the ssi
9434: call.
9435: ssi_error_message - The error string fetched from the ssi response
9436: in the event of an error.

9450: specific error condition in a specific scanline
9451:
9452: Arguments:
9453: $r - Apache request object
9454: $i - number of the current scanline
9455: $scan_record - hash ref as returned from &scantron_parse_scanline()
9456: $scan_config - hash ref as returned from &get_scantron_config()
9457: $line - full contents of the current scanline
9458: $error - error condition, valid values are
9459: 'incorrectCODE', 'duplicateCODE',
9460: 'doublebubble', 'missingbubble',
9461: 'duplicateID', 'incorrectID'
9462: $arg - extra information needed
9463: For errors:
9464: - duplicateID - paper number that this studentID was seen before on
9465: - duplicateCODE - array ref of the paper numbers this CODE was
9466: seen on before
9467: - incorrectCODE - current incorrect CODE
9468: - doublebubble - array ref of the bubble lines that have double
9469: bubble errors

9471: bubble errors

1.574.2.7! raeburn 9475: Arguments:

! 9477: failure to retrieve a navmap object.
! 9478: if $nav_error is set to 1 by scantron_get_maxbubble(), the
! 9479: calling routine should trap the error condition and display the warning
! 9480: found in &navmap_errormsg().
! 9481:
1.531 jms 9482: Returns the maximum number of bubble lines that are expected to
9483: occur. Does this by walking the selected sequence rendering the
9484: resource and then checking &Apache::lonxml::get_problem_counter()

9486:
9487: Caches the results to $env{'form.scantron_maxbubble'},
9488: $env{'form.scantron.bubble_lines.n'},
9489: $env{'form.scantron.first_bubble_line.n'} and
9490: $env{"form.scantron.sub_bubblelines.n"}
9491: which are the total number of bubble, lines, the number of bubble
9492: lines for response n and number of the first bubble line for response n,
9493: and a comma separated list of numbers of bubble lines for sub-questions

9503: =item scantron_process_students() :
9504:
9505: Routine that does the actual grading of the bubble sheet information.
9506:
9507: The parsed scanline hash is added to %env
9508:
9509: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9510: foreach resource , with the form data of
9511:

9517: 'grade_symb' => symb of resource to grade
9518:
9519: This triggers a grading pass. The problem grading code takes care
