1.424 albertel 5086: For this documentation:
5087:
5088: 'scanline' refers to the full line of characters
5089: from the file that we are parsing that represents one entire sheet
5090:
5091: 'bubble line' refers to the data
1.659 raeburn 5092: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5093:
5094:
1.659 raeburn 5095: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5096: into a course. When a user wants to grade, they select a
1.659 raeburn 5097: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5098: one of the predefined configurations for what each scanline looks
5099: like.
5100:
5101: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5102: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5103: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5104: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5105: invalid student/employee ID
1.424 albertel 5106:
5107: If the CODE option is used that determines the randomization of the
1.556 weissno 5108: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5109: username:domain.
5110:
5111: During the validation phase the instructor can choose to skip scanlines.
5112:
1.659 raeburn 5113: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5114:
5115: scantron_original_filename (unmodified original file)
5116: scantron_corrected_filename (file where the corrected information has replaced the original information)
5117: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5118:
5119: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5120: correction information that isn't representable in the bubblesheet
1.424 albertel 5121: file (see &scantron_getfile() for more information)
5122:
5123: After all scanlines are either valid, marked as valid or skipped, then
5124: foreach line foreach problem in the picked sequence, an ssi request is
5125: made that simulates a user submitting their selected letter(s) against
5126: the homework problem.

10358:
10359: =head1 SYNOPSIS
10360:
10361: Handles the viewing of grades.
10362:
10363: This is part of the LearningOnline Network with CAPA project
10364: described at http://www.lon-capa.org.
10365:
10366: =head1 OVERVIEW
10367:
10368: Do an ssi with retries:
1.715 bisitz 10369: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10370: 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
10371: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10372:
10373: At least the logic that drives this has been pulled out into loncommon.
10374:
10375:
10376:
10377: ssi_with_retries - Does the server side include of a resource.
10378: if the ssi call returns an error we'll retry it up to
10379: the number of times requested by the caller.
1.715 bisitz 10380: If we still have a problem, no text is appended to the
1.531 jms 10381: output and we set some global variables.
10382: to indicate to the caller an SSI error occurred.
10383: All of this is supposed to deal with the issues described
1.715 bisitz 10384: in LON-CAPA BZ 5631 see:
1.531 jms 10385: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10386: by informing the user that this happened.
10387:
10388: Parameters:
10389: resource - The resource to include. This is passed directly, without
10390: interpretation to lonnet::ssi.
10391: form - The form hash parameters that guide the interpretation of the resource
10392:
10393: retries - Number of retries allowed before giving up completely.
10394: Returns:
10395: On success, returns the rendered resource identified by the resource parameter.
10396: Side Effects:
10397: The following global variables can be set:
10398: ssi_error - If an unrecoverable error occurred this becomes true.
10399: It is up to the caller to initialize this to false
10400: if desired.
10401: ssi_error_resource - If an unrecoverable error occurred, this is the value
10402: of the resource that could not be rendered by the ssi
10403: call.
10404: ssi_error_message - The error string fetched from the ssi response
10405: in the event of an error.

1.671 raeburn 10416: =head1 Routines to display previous version of a Task for a specific student
10417:
10418: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10419: can receive another opportunity. Access to tasks is slot-based. If a slot
10420: requires a proctor to check-in the student, a new version of the Task will
10421: be created when the student is checked in to the new opportunity.
10422:
10423: If a particular student has tried two or more versions of a particular task,
10424: the submission screen provides a user with vgr privileges (e.g., a Course
10425: Coordinator) the ability to display a previous version worked on by the
10426: student. By default, the current version is displayed. If a previous version
10427: has been selected for display, submission data are only shown that pertain
10428: to that particular version, and the interface to submit grades is not shown.

10439:

10441:
10442: Side Effects: calls &show_problem() to print version of Task, with

10444:
10445: =item choose_task_version_form()

10449: content in existing pop-up, or replaces page in main window.
10450:
10451: Inputs: 4
10452: symb - unique symb for current instance of resource
10453: uname - username of student
10454: udom - domain of student

10456: breadcrumbs etc., are displayed
10457:
10458: Output: 4
10459: current - student's current version
10460: displayed - student's version being displayed
10461: result - scalar containing HTML for web form used to switch to
10462: a different version (or a link to close window, if pop-up).
10463: js - javascript for processing selection in versions web form
10464:
