Having a look at .../lib/dmllib.php it seems this warning is issued when the SQL sentence uses one of the obsolete tables (from 1.7 on) prefix_user_students, prefix_user_teachers, prefix_user_coursecreators and prefix_user_admins.

All of those tables are gone and the code should be using the new roles system. So you _really_ need a developer to fix that code چشمک

Saludos. Iñaki.

It is possible, of course, to hack the dmllib.php file to allow you to use the old tables, but that is not the spirit of 1.7 ;), in either case you still need a developer.

The code causing your problems is probably a third party module or block. Backup and restore your course and in the copy try removing each third party module, hopefully you will find the offending plugin.

Iñaki, You are right! The course format project is using the tables: user_teachers, user_students!! thanks for the clue..

So, how can I change these calls into the spirit of 1.7/1.8?

  $teachers = get_records('user_teachers','course',$courseid);
  $students = get_records('user_students','course',$courseid);
    $teacher = get_record('user_teachers', 'userid', $USER->id, 'course', $course->id)

Users are now defined by roles, type show tables like '%roles%' at the MySQL client prompt to see the tables involved.

You will now need to group users by what capabilities their roles have, for example if I have block which I want only users that are able to use the chat module to edit, then I would need to include the following code somewhere in my_block's code:
...
$blockobject = block_instance('my_block', $bi);

$context = get_context_instance(CONTEXT_COURSE,
 blockobject->instance->pageid);

require_capability('mod/chat:chat', $context);
...
For further information on roles see Managing Roles.

Why do you want that information? What do you do with it? We need more information to be able to tell you what to do under roles and capabilites.

Hi all,
if you don't make too much use of roles maybe that simple hack on /lib/dmllib.php may be usefull.

Please don't try it on a production server, and test all the role you will need before concluding it working.

I hope it may help,

Bernard

Thank you very much Bernard, that did the trick!!

I now wonder why they coded it as an error instead of an:  

if (isadmin()) {WARNING!!}

Just wondering: created you already with jpGraph a 360 grade modul where students fill questions about each other and jpGraph creates a kind of Radar-grpah?

Hi Ger,
the radar graphs that I remember to have posted here are there and are part of my old project Socrate for wich I got some funding big grin ( free time to work on next year ) but they are created with excel.

But Jpgraph is able to generate equivalents.

I hope it may help,

Bernard

p.s. The mindmap of the second link Socrate is not yet clickable like yours but it will be soonwink and I think you will like it!
