1.424 albertel 5921: For this documentation:
5922:
5923: 'scanline' refers to the full line of characters
5924: from the file that we are parsing that represents one entire sheet
5925:
5926: 'bubble line' refers to the data
1.659 raeburn 5927: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5928:
5929:
1.659 raeburn 5930: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5931: into a course. When a user wants to grade, they select a
1.659 raeburn 5932: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5933: one of the predefined configurations for what each scanline looks
5934: like.
5935:
5936: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5937: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5938: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5939: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5940: invalid student/employee ID
1.424 albertel 5941:
5942: If the CODE option is used that determines the randomization of the
1.556 weissno 5943: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5944: username:domain.
5945:
5946: During the validation phase the instructor can choose to skip scanlines.
5947:
1.659 raeburn 5948: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5949:
5950: scantron_original_filename (unmodified original file)
5951: scantron_corrected_filename (file where the corrected information has replaced the original information)
5952: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5953:
5954: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5955: correction information that isn't representable in the bubblesheet
1.424 albertel 5956: file (see &scantron_getfile() for more information)
5957:
5958: After all scanlines are either valid, marked as valid or skipped, then
5959: foreach line foreach problem in the picked sequence, an ssi request is
5960: made that simulates a user submitting their selected letter(s) against
5961: the homework problem.

11917:
11918: =head1 SYNOPSIS
11919:
11920: Handles the viewing of grades.
11921:
11922: This is part of the LearningOnline Network with CAPA project
11923: described at http://www.lon-capa.org.
11924:
11925: =head1 OVERVIEW
11926:
11927: Do an ssi with retries:
1.715 bisitz 11928: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11929: 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
11930: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11931:
11932: At least the logic that drives this has been pulled out into loncommon.
11933:
11934:
11935:
11936: ssi_with_retries - Does the server side include of a resource.
11937: if the ssi call returns an error we'll retry it up to
11938: the number of times requested by the caller.
1.715 bisitz 11939: If we still have a problem, no text is appended to the
1.531 jms 11940: output and we set some global variables.
11941: to indicate to the caller an SSI error occurred.
11942: All of this is supposed to deal with the issues described
1.715 bisitz 11943: in LON-CAPA BZ 5631 see:
1.531 jms 11944: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11945: by informing the user that this happened.
11946:
11947: Parameters:
11948: resource - The resource to include. This is passed directly, without
11949: interpretation to lonnet::ssi.
11950: form - The form hash parameters that guide the interpretation of the resource
11951:
11952: retries - Number of retries allowed before giving up completely.
11953: Returns:
11954: On success, returns the rendered resource identified by the resource parameter.
11955: Side Effects:
11956: The following global variables can be set:
11957: ssi_error - If an unrecoverable error occurred this becomes true.
11958: It is up to the caller to initialize this to false
11959: if desired.
11960: ssi_error_resource - If an unrecoverable error occurred, this is the value
11961: of the resource that could not be rendered by the ssi
11962: call.
11963: ssi_error_message - The error string fetched from the ssi response
11964: in the event of an error.

1.671 raeburn 11975: =head1 Routines to display previous version of a Task for a specific student
11976:
11977: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11978: can receive another opportunity. Access to tasks is slot-based. If a slot
11979: requires a proctor to check-in the student, a new version of the Task will
11980: be created when the student is checked in to the new opportunity.
11981:
11982: If a particular student has tried two or more versions of a particular task,
11983: the submission screen provides a user with vgr privileges (e.g., a Course
11984: Coordinator) the ability to display a previous version worked on by the
11985: student. By default, the current version is displayed. If a previous version
11986: has been selected for display, submission data are only shown that pertain
11987: to that particular version, and the interface to submit grades is not shown.
