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.
Remove the responsibility for loging the application of the course start date offset, from activity modules to the backup module.
Merged from stable branch
* Add fields to restore form to enable changes to Short Name, Full Name and Start Date
* Start Date offset added to Restore process
* Created Restorelog file in Course files area
* Activity Modules use offset to change dates
* Activity Modules write changes to Restorelog
Added new function, import_backup_file_silently
Changed everything that prints stuff to check for a constant first.
Backup_flush checks a different constant, this is so that output can still
get flushed to the browser when necessary but not print <li>s everywhere.
Please test this!
This patch allows the much requested selection of individual instances of modules within a course to backup and restore.
It needs A LOT of testing and probably some prettyifying too.
done globally after restoring all the categories by restore_create_questions()
in backup/restorelib.php
Modify the restore of numericalquestions to work with its new 1.5 structure.
