This achieves a massive clean-up. It simplifies comples code in a number
of places. It allows some methods and functions to be moved to a more
appropriate home (for example cannot_review_message to the quiz class).
It moves more logic out of the renderer.
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.
At the same time I have converted the calendar block to use YUI instead of overlib, this introduces one regression in that the panel is shown immediatly but should really have a minimal delay for usability.
This will be fixed once the theme changes for 2.0 have been commited
And MDL-17568 minor niggles with new queston navigation:
* The bit that scrolls down to the question you just submitted in adaptive mode was not working with random questions.
* Teachers reviewing an open attempt were shown the qusetions as editable, not read only!
MDL-16559 Remove question/comment.html template, and instead just have a function in questionlib.php
MDL-16562 Regression from MDL-16263, notices when regrading.
Sorry, the three got tangled together (coupled through questionlib) while I was fixing bugs in preparation for a demo.
I have not converted the rest of the quiz, and I don't intend to. I am hoping Moodle.com will do it.
I hope this does not introduce any bugs, but view.php is so complicate (at least it is less complicated than it was) and the quiz has so many options, that it is hard to be sure. This needs lots of testing before 1.7 is released.
I have not been able to test this fully, because I cannot assign roles (e.g. Student and Teacher) in 1.7dev at the moment to test a student answering an essay question then a teacher grading it. However, I have tested as much as possible as admin and cannot get any errors.
