5767:
1.424 albertel 5768: For this documentation:
5769:
5770: 'scanline' refers to the full line of characters
5771: from the file that we are parsing that represents one entire sheet
5772:
5773: 'bubble line' refers to the data
1.659 raeburn 5774: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5775:
5776:
1.659 raeburn 5777: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5778: into a course. When a user wants to grade, they select a
1.659 raeburn 5779: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5780: one of the predefined configurations for what each scanline looks
5781: like.
5782:
5783: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5784: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5785: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5786: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5787: invalid student/employee ID
1.424 albertel 5788:
5789: If the CODE option is used that determines the randomization of the
1.556 weissno 5790: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5791: username:domain.
5792:
5793: During the validation phase the instructor can choose to skip scanlines.
5794:
1.659 raeburn 5795: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5796:
5797: scantron_original_filename (unmodified original file)
5798: scantron_corrected_filename (file where the corrected information has replaced the original information)
5799: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5800:
5801: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5802: correction information that isn't representable in the bubblesheet
1.424 albertel 5803: file (see &scantron_getfile() for more information)
5804:
5805: After all scanlines are either valid, marked as valid or skipped, then
5806: foreach line foreach problem in the picked sequence, an ssi request is
5807: made that simulates a user submitting their selected letter(s) against
5808: the homework problem.

11611:
11612: Apache::grades
11613:
11614: =head1 SYNOPSIS
11615:
11616: Handles the viewing of grades.
11617:
11618: This is part of the LearningOnline Network with CAPA project
11619: described at http://www.lon-capa.org.
11620:
11621: =head1 OVERVIEW
11622:
11623: Do an ssi with retries:
1.715 bisitz 11624: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11625: 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
11626: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11627:
11628: At least the logic that drives this has been pulled out into loncommon.
11629:
11630:
11631:
11632: ssi_with_retries - Does the server side include of a resource.
11633: if the ssi call returns an error we'll retry it up to
11634: the number of times requested by the caller.
1.715 bisitz 11635: If we still have a problem, no text is appended to the
1.531 jms 11636: output and we set some global variables.
11637: to indicate to the caller an SSI error occurred.
11638: All of this is supposed to deal with the issues described
1.715 bisitz 11639: in LON-CAPA BZ 5631 see:
1.531 jms 11640: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11641: by informing the user that this happened.
11642:
11643: Parameters:
11644: resource - The resource to include. This is passed directly, without
11645: interpretation to lonnet::ssi.
11646: form - The form hash parameters that guide the interpretation of the resource
11647:
11648: retries - Number of retries allowed before giving up completely.
11649: Returns:
11650: On success, returns the rendered resource identified by the resource parameter.
11651: Side Effects:
11652: The following global variables can be set:
11653: ssi_error - If an unrecoverable error occurred this becomes true.
11654: It is up to the caller to initialize this to false
11655: if desired.
11656: ssi_error_resource - If an unrecoverable error occurred, this is the value
11657: of the resource that could not be rendered by the ssi
11658: call.
11659: ssi_error_message - The error string fetched from the ssi response
11660: in the event of an error.

11670:
1.671 raeburn 11671: =head1 Routines to display previous version of a Task for a specific student
11672:
11673: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11674: can receive another opportunity. Access to tasks is slot-based. If a slot
11675: requires a proctor to check-in the student, a new version of the Task will
11676: be created when the student is checked in to the new opportunity.
11677:
11678: If a particular student has tried two or more versions of a particular task,
11679: the submission screen provides a user with vgr privileges (e.g., a Course
11680: Coordinator) the ability to display a previous version worked on by the
11681: student. By default, the current version is displayed. If a previous version
11682: has been selected for display, submission data are only shown that pertain
11683: to that particular version, and the interface to submit grades is not shown.

11696:
11697: Side Effects: calls &show_problem() to print version of Task, with

11699:
11700: =item choose_task_version_form()
11701:

11704: content in existing pop-up, or replaces page in main window.
11705:

11712:
11713: Output: 4
11714: current - student's current version
11715: displayed - student's version being displayed
11716: result - scalar containing HTML for web form used to switch to
11717: a different version (or a link to close window, if pop-up).
11718: js - javascript for processing selection in versions web form
