xowf::test_item::grading::Grading method grading_dict (public)

 <instance of xowf::test_item::grading::Grading[i]> grading_dict \
    achieved_points

Important dict members of "achieved_points": - achievedPoints: points that the student has achieved in her exam - achievablePoints: points that the student could have achieved so far - totalPoints: points that the student can achieve when finishing the exam achieved_points: {achievedPoints 4.0 achievablePoints 4 totalPoints 4} percentage_mapping: {50.0 60.0 70.0 80.0} While "achievedPoints" and "achievablePoints" are calculated by iterating over the submitted values, "totalPoints" contains the sum of points of all questions of the exam, no matter if these were answered or not.

Parameters:
achieved_points (required)

Testcases:
create_test_items

xowf::test_item::grading::Grading method print (public)

 <instance of xowf::test_item::grading::Grading[i]> print \
    -achieved_points achieved_points

Return a dict containing the members "panel" and "csv" depending on the type of rounding options

Switches:
-achieved_points (required)

Testcases:
create_test_items

xowf::test_item::grading::GradingNone method grade (public)

 <instance of xowf::test_item::grading::GradingNone[i]> grade \
    -achieved_points achieved_points

No grading scheme defined, return grading 0.

Switches:
-achieved_points (required)

Testcases:
create_test_items

xowf::test_item::grading::GradingRoundNone method grade (public)

 <instance of xowf::test_item::grading::GradingRoundNone[i]> grade \
    -achieved_points achieved_points

Return a numeric grade for an exam submission based with no special rounding (2 digits). On invalid data, return 0.

Switches:
-achieved_points (required)

Testcases:
No testcase defined.

xowf::test_item::grading::GradingRoundPercentage method grade (public)

 <instance of xowf::test_item::grading::GradingRoundPercentage[i]> grade \
    -achieved_points achieved_points

Return a numeric grade for an exam submission based on rounded percentage. On invalid data, return 0.

Switches:
-achieved_points (required)

Testcases:
No testcase defined.

xowf::test_item::grading::GradingRoundPoints method grade (public)

 <instance of xowf::test_item::grading::GradingRoundPoints[i]> grade \
    -achieved_points achieved_points

Return a numeric grade for an exam submission based on rounded points. On invalid data, return 0.

Switches:
-achieved_points (required)

Testcases:
No testcase defined.

xowf::test_item::grading::load_grading_schemes (public)

 xowf::test_item::grading::load_grading_schemes -package_id package_id \
    -parent_id parent_id

Load the actual grading scheme objects defined for the package_id and parent_id. It might be the case that this function is called multiple times by a single request (when e.g. multiple exams are on a single page). So we are caching the result to avoid repeated computations of the same result.

Switches:
-package_id (required)
-parent_id (required)
