5915:
1.424 albertel 5916: For this documentation:
5917:
5918: 'scanline' refers to the full line of characters
5919: from the file that we are parsing that represents one entire sheet
5920:
5921: 'bubble line' refers to the data
1.659 raeburn 5922: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5923:
5924:
1.659 raeburn 5925: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5926: into a course. When a user wants to grade, they select a
1.659 raeburn 5927: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5928: one of the predefined configurations for what each scanline looks
5929: like.
5930:
5931: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5932: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5933: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5934: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5935: invalid student/employee ID
1.424 albertel 5936:
5937: If the CODE option is used that determines the randomization of the
1.556 weissno 5938: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5939: username:domain.
5940:
5941: During the validation phase the instructor can choose to skip scanlines.
5942:
1.659 raeburn 5943: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5944:
5945: scantron_original_filename (unmodified original file)
5946: scantron_corrected_filename (file where the corrected information has replaced the original information)
5947: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5948:
5949: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5950: correction information that isn't representable in the bubblesheet
1.424 albertel 5951: file (see &scantron_getfile() for more information)
5952:
5953: After all scanlines are either valid, marked as valid or skipped, then
5954: foreach line foreach problem in the picked sequence, an ssi request is
5955: made that simulates a user submitting their selected letter(s) against
5956: the homework problem.

11912:
11913: =head1 SYNOPSIS
11914:
11915: Handles the viewing of grades.
11916:
11917: This is part of the LearningOnline Network with CAPA project
11918: described at http://www.lon-capa.org.
11919:
11920: =head1 OVERVIEW
11921:
11922: Do an ssi with retries:
1.715 bisitz 11923: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11924: 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
11925: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11926:
11927: At least the logic that drives this has been pulled out into loncommon.
11928:
11929:
11930:
11931: ssi_with_retries - Does the server side include of a resource.
11932: if the ssi call returns an error we'll retry it up to
11933: the number of times requested by the caller.
1.715 bisitz 11934: If we still have a problem, no text is appended to the
1.531 jms 11935: output and we set some global variables.
11936: to indicate to the caller an SSI error occurred.
11937: All of this is supposed to deal with the issues described
1.715 bisitz 11938: in LON-CAPA BZ 5631 see:
1.531 jms 11939: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11940: by informing the user that this happened.
11941:
11942: Parameters:
11943: resource - The resource to include. This is passed directly, without
11944: interpretation to lonnet::ssi.
11945: form - The form hash parameters that guide the interpretation of the resource
11946:
11947: retries - Number of retries allowed before giving up completely.
11948: Returns:
11949: On success, returns the rendered resource identified by the resource parameter.
11950: Side Effects:
11951: The following global variables can be set:
11952: ssi_error - If an unrecoverable error occurred this becomes true.
11953: It is up to the caller to initialize this to false
11954: if desired.
11955: ssi_error_resource - If an unrecoverable error occurred, this is the value
11956: of the resource that could not be rendered by the ssi
11957: call.
11958: ssi_error_message - The error string fetched from the ssi response
11959: in the event of an error.

1.671 raeburn 11970: =head1 Routines to display previous version of a Task for a specific student
11971:
11972: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11973: can receive another opportunity. Access to tasks is slot-based. If a slot
11974: requires a proctor to check-in the student, a new version of the Task will
11975: be created when the student is checked in to the new opportunity.
11976:
11977: If a particular student has tried two or more versions of a particular task,
11978: the submission screen provides a user with vgr privileges (e.g., a Course
11979: Coordinator) the ability to display a previous version worked on by the
11980: student. By default, the current version is displayed. If a previous version
11981: has been selected for display, submission data are only shown that pertain
11982: to that particular version, and the interface to submit grades is not shown.
