1.424 albertel 5039: For this documentation:
5040:
5041: 'scanline' refers to the full line of characters
5042: from the file that we are parsing that represents one entire sheet
5043:
5044: 'bubble line' refers to the data
1.659 raeburn 5045: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5046:
5047:
1.659 raeburn 5048: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5049: into a course. When a user wants to grade, they select a
1.659 raeburn 5050: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5051: one of the predefined configurations for what each scanline looks
5052: like.
5053:
5054: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5055: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5056: because too light bubbling), 'double bubble' (each bubble line should
5057: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5058: invalid student/employee ID
1.424 albertel 5059:
5060: If the CODE option is used that determines the randomization of the
1.556 weissno 5061: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5062: username:domain.
5063:
5064: During the validation phase the instructor can choose to skip scanlines.
5065:
1.659 raeburn 5066: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5067:
5068: scantron_original_filename (unmodified original file)
5069: scantron_corrected_filename (file where the corrected information has replaced the original information)
5070: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5071:
5072: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5073: correction information that isn't representable in the bubblesheet
1.424 albertel 5074: file (see &scantron_getfile() for more information)
5075:
5076: After all scanlines are either valid, marked as valid or skipped, then
5077: foreach line foreach problem in the picked sequence, an ssi request is
5078: made that simulates a user submitting their selected letter(s) against
5079: the homework problem.

9859: =head1 NAME
9860:
9861: Apache::grades
9862:
9863: =head1 SYNOPSIS
9864:
9865: Handles the viewing of grades.
9866:
9867: This is part of the LearningOnline Network with CAPA project
9868: described at http://www.lon-capa.org.
9869:
9870: =head1 OVERVIEW
9871:
9872: Do an ssi with retries:
9873: While I'd love to factor out this with the vesrion in lonprintout,
9874: 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
9875: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9876:
9877: At least the logic that drives this has been pulled out into loncommon.
9878:
9879:
9880:
9881: ssi_with_retries - Does the server side include of a resource.
9882: if the ssi call returns an error we'll retry it up to
9883: the number of times requested by the caller.
9884: If we still have a proble, no text is appended to the
9885: output and we set some global variables.
9886: to indicate to the caller an SSI error occurred.
9887: All of this is supposed to deal with the issues described
9888: in LonCAPA BZ 5631 see:
9889: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9890: by informing the user that this happened.
9891:
9892: Parameters:
9893: resource - The resource to include. This is passed directly, without
9894: interpretation to lonnet::ssi.
9895: form - The form hash parameters that guide the interpretation of the resource
9896:
9897: retries - Number of retries allowed before giving up completely.
9898: Returns:
9899: On success, returns the rendered resource identified by the resource parameter.
9900: Side Effects:
9901: The following global variables can be set:
9902: ssi_error - If an unrecoverable error occurred this becomes true.
9903: It is up to the caller to initialize this to false
9904: if desired.
9905: ssi_error_resource - If an unrecoverable error occurred, this is the value
9906: of the resource that could not be rendered by the ssi
9907: call.
9908: ssi_error_message - The error string fetched from the ssi response
9909: in the event of an error.

1.671 raeburn 9920: =head1 Routines to display previous version of a Task for a specific student
9921:
9922: Tasks are graded pass/fail. Students who have yet to pass a particular Task
9923: can receive another opportunity. Access to tasks is slot-based. If a slot
9924: requires a proctor to check-in the student, a new version of the Task will
9925: be created when the student is checked in to the new opportunity.
9926:
9927: If a particular student has tried two or more versions of a particular task,
9928: the submission screen provides a user with vgr privileges (e.g., a Course
9929: Coordinator) the ability to display a previous version worked on by the
9930: student. By default, the current version is displayed. If a previous version
9931: has been selected for display, submission data are only shown that pertain
9932: to that particular version, and the interface to submit grades is not shown.

9954:

9960: breadcrumbs etc., are displayed
9961:
9962: Output: 4
9963: current - student's current version
9964: displayed - student's version being displayed
9965: result - scalar containing HTML for web form used to switch to
9966: a different version (or a link to close window, if pop-up).
9967: js - javascript for processing selection in versions web form
9968:
9969: Side Effects: None.

9971: =item previous_display_javascript()
9972:
9973: Inputs: 2
