Tim Hunt	94815ccfa0	MDL-30484 question engine: don't lose response files when regrading. ... The problem was mostly that, in the past, we did not worry if question_attempt_step.id changed during regrade (because we deleted the old step row and inserted a new one). However, now that steps can have associated files, we can't be that slack, becuase the step id is used as the file itemid. So, now, we have to update the existing rows during a regrade. We do this by having the question engine tell the question_engine_unit_of_work that the step has first been deleted, and then added back. Then we make the unit-of-work spot that delete + add = update. This also means that during regrading, we have to pass around some extra ids so that new steps know the id of the step they are replacing. Naturally, this requires some quite trickly logic, so I finally got around to writing unit tests for question_engine_unit_of_work, which is a good thing. Along the way I also got around to renaming question_attempt->set_number_in_usage, which got missed out when everthing else was renamed to slot ages ago. Finally, while working on this code, I noticed and fixed some PHPdoc comments.	2012-01-30 16:57:23 +00:00

Tim Hunt	35d5f1c28d	MDL-27948 The question engine should use recordsets to load attempt data ... This should be good for performance (memory usage). It also avoids having to construct a meaningless, unique, first column, which is a pain on MyQSL.	2011-06-22 18:53:15 +01:00
Tim Hunt	97cdc1de72	MDL-27747 quiz summary, add a CSS class to the table rows based on question state. ... The standard themes do not use this for anything, but it makes it easier for themers to do cool stuff. Also improve the API for getting the question state class.	2011-06-07 15:11:04 +01:00
