5863:
1.424 albertel 5864: For this documentation:
5865:
5866: 'scanline' refers to the full line of characters
5867: from the file that we are parsing that represents one entire sheet
5868:
5869: 'bubble line' refers to the data
1.659 raeburn 5870: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5871:
5872:
1.659 raeburn 5873: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5874: into a course. When a user wants to grade, they select a
1.659 raeburn 5875: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5876: one of the predefined configurations for what each scanline looks
5877: like.
5878:
5879: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5880: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5881: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5882: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5883: invalid student/employee ID
1.424 albertel 5884:
5885: If the CODE option is used that determines the randomization of the
1.556 weissno 5886: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5887: username:domain.
5888:
5889: During the validation phase the instructor can choose to skip scanlines.
5890:
1.659 raeburn 5891: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5892:
5893: scantron_original_filename (unmodified original file)
5894: scantron_corrected_filename (file where the corrected information has replaced the original information)
5895: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5896:
5897: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5898: correction information that isn't representable in the bubblesheet
1.424 albertel 5899: file (see &scantron_getfile() for more information)
5900:
5901: After all scanlines are either valid, marked as valid or skipped, then
5902: foreach line foreach problem in the picked sequence, an ssi request is
5903: made that simulates a user submitting their selected letter(s) against
5904: the homework problem.

11727:
11728: Apache::grades
11729:
11730: =head1 SYNOPSIS
11731:
11732: Handles the viewing of grades.
11733:
11734: This is part of the LearningOnline Network with CAPA project
11735: described at http://www.lon-capa.org.
11736:
11737: =head1 OVERVIEW
11738:
11739: Do an ssi with retries:
1.715 bisitz 11740: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11741: 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
11742: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11743:
11744: At least the logic that drives this has been pulled out into loncommon.
11745:
11746:
11747:
11748: ssi_with_retries - Does the server side include of a resource.
11749: if the ssi call returns an error we'll retry it up to
11750: the number of times requested by the caller.
1.715 bisitz 11751: If we still have a problem, no text is appended to the
1.531 jms 11752: output and we set some global variables.
11753: to indicate to the caller an SSI error occurred.
11754: All of this is supposed to deal with the issues described
1.715 bisitz 11755: in LON-CAPA BZ 5631 see:
1.531 jms 11756: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11757: by informing the user that this happened.
11758:
11759: Parameters:
11760: resource - The resource to include. This is passed directly, without
11761: interpretation to lonnet::ssi.
11762: form - The form hash parameters that guide the interpretation of the resource
11763:
11764: retries - Number of retries allowed before giving up completely.
11765: Returns:
11766: On success, returns the rendered resource identified by the resource parameter.
11767: Side Effects:
11768: The following global variables can be set:
11769: ssi_error - If an unrecoverable error occurred this becomes true.
11770: It is up to the caller to initialize this to false
11771: if desired.
11772: ssi_error_resource - If an unrecoverable error occurred, this is the value
11773: of the resource that could not be rendered by the ssi
11774: call.
11775: ssi_error_message - The error string fetched from the ssi response
11776: in the event of an error.

1.671 raeburn 11787: =head1 Routines to display previous version of a Task for a specific student
11788:
11789: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11790: can receive another opportunity. Access to tasks is slot-based. If a slot
11791: requires a proctor to check-in the student, a new version of the Task will
11792: be created when the student is checked in to the new opportunity.
11793:
11794: If a particular student has tried two or more versions of a particular task,
11795: the submission screen provides a user with vgr privileges (e.g., a Course
11796: Coordinator) the ability to display a previous version worked on by the
11797: student. By default, the current version is displayed. If a previous version
11798: has been selected for display, submission data are only shown that pertain
11799: to that particular version, and the interface to submit grades is not shown.
