Some columns needed to be renamed:
* quiz -> quizid
* question -> questionid
* grade -> maxmark
Then all the places that refer to those needed to be fixed.
Melinda Kraft reported having rows in their quiz_question_instances
table which caused various problems. These rows are meaningless, so I
have done a DB upgrade step to clean them up, which should deal with the
bad side-effets they were causing.
* Support for old non-standard cron for quiz reports dropped. (Standard
cron support was added in 2.2
* Cron support added for qbehaviour, qformat and quizacces plugins.
* qtypes were already supported in the standard way.
This avoids the problem that you cannot send messages in transactions.
It also means that the quiz submission will not be prevented, and the
message will still be sent eventually, if any part of the messaging
system is giving intermittent errors when the student wants to submit
their quiz.
* Routine navigation through the quiz and question modules
* Fixed navbar through quiz and questions
* Pages headers added throughout
* Added method to turn a navigation node into a tabs array suitable for use with print tabs
This was implemented by Matt Petro of the University of Wisconsin - Madison Engineering
School and Math Department. Many thanks. Reviewed by and committed by Tim Hunt.
This adds a new Overrides tab to the UI, with sub-tabs Group overrides and User overrides.
Each of those lists all the overrides that currently exist, and lets you manage them and
create more.
When a quiz is being attempted, the override that applies to the current user is combined
with the current quiz settings loaded from the quiz table (normally called $quiz).
If there are both user and group overrides, then just the specific user override is used (more specific).
If the user is in several groups, then the overrides are combined to give the most permissive set of options.
There is one new database table quiz_overrides, to store the overrides.
* Reorder form fields to group things more logically.
** and on the corresponding admin page too.
* Set some options to be 'Advanced' by default:
** Apply penalties.
** Each attempt builds on the last.
** Decimal places for question grades.
** The five 'Extra restrictions on attempts' settings. (password, etc.)
* Admins can still change this to suit their institiution at Administration > Plugins > Activity modules > Quiz.
* These new defaults are applied if the admin had not previously set any fields to be advanced.
* Disable some filds when they are not applicable:
** Grading method, if num attempts = 1
** Penaly scheme, if adaptive mode = no
** Each attempt builds of last, if num attempts = 1
** Review after quiz closed options, if no close date.
** Delay between 1st and 2nd attempts, if num attempts = 1
** Delay between later attempts, if num attempts < 3
* Convert quiz.timelimit to be in seconds, for consistency, and ready for the new duration field type (MDL 18500).
** Including ensuring that backup and restore is backwards compatible.
* MDL-5537 New setting, questiondecimalpoints, so, for example, you can show the quiz grade as an integer, but have fractional question grades.
** There is a 'Same as overall decimal points' option, which is the default.
* Improve some field labels.
* Make corresponding changes in the help files.
