Moodle tables.
ie user -> userid in many tables, plus in user_students
start -> starttime and end -> endtime
I've just done all this as carefully as I could ... I don't think
I missed anything but it's pretty intensive work and I'd be fooling myself
if I didn't think I'd missed a couple.
Note that this version should pretty much be able to bootstrap itself
using PostgreSQL now ... but this is untested
Basically all the Database functions are in lib/datalib.php
and the web functions are all in lib/weblib.php, so
moodlelib.php is much thinner than it was.
Data functions have been extended ... most old calls will
still work, but now many more SQL commands can be performed
using the datalib functions rather than using SQL. I'm
currently moving through the whole tree replacing SQL
calls or at least concentrating them in one section of
mod/xxx/lib.php
Still working on forums, quizzes, surveys, resources.
The tree is currently not full working ... some things are
half-completed ... will resume tomorrow.
record upon showing the quiz, and completing it upon submit.
Two new fields in quiz_attempts... should be upgrade friendly.
(Old attempts will show up as being of duration zero)
Also some small fixes here and there.
If you have existing quizzes, delete them all, then
drop all the quiz tables and delete the quiz line from
the modules table.
Things to do still:
- add/edit/remove categories
- display question feedback on submissions ...
- record the time they started the quiz, as well as the completion.
- place time limits between attempts
- add full specification of quiz open time and quiz close time
At this stage this module:
- prints quizzes,
- accepts answers (for multiple attempts) and grades them,
- stores the grades.
Really, it's usable as long as you don't mind using the database manually. :)
Next up is quiz reports, then I'll tackle quiz creation.
but can't mark them yet. I've been constructing quizzes manually in the
database and it's helping to refine the database structure. Don't count
on anything stable in the quiz module for a few days yet ...
