Hi

I am using Joomdle version 1.2.4 and to display the grades I am using the "User courses grades" view

When trying to view the grades I get the error below, strange thing is the error seems to only show on one of the courses the rest display correctly.
This course displayed correctly previously but all of a sudden it does not.

Hi.

First thing is to enable debugging in Moodle, and then trigger the error, so we can try to have more info about it.

Hi. I could not replicate the error, but looking at the code I can give you a proposed fix so you can try it. If it does not work, we can investigate further.

Change is to be made in file: moodle/auth/joomdle/auth.php
Function: get_grade_user_report
After this block:

Code:

                if ($module)
                {
                    $conditions = array ('course' => $item->courseid, 'module' => $module->id, 'instance' => $item->iteminstance);
                    $cm = $DB->get_record('course_modules', $conditions);

                    $category_item['course_module_id'] = $cm->id;

                    switch ($item->itemmodule) {
                        case 'quiz':
                            $conditions = array ('id' => $item->iteminstance);
                            $quiz = $DB->get_record('quiz', $conditions);
                            $category_item['due'] = $quiz->timeclose;
                            break;
                        case 'assignment':
                            $conditions = array ('id' => $item->iteminstance);
                            $assignment = $DB->get_record('assignment', $conditions);
                            $category_item['due'] = $assignment->timedue;
                            break;
                        default:
                            $category_item['due'] = 0;
                            break;
                    }
                }

Add:

Code:

                else
                    $category_item['due'] = 0;

Please test and let us know how it goes.

Is it possible to share a course backup so I can test it locally? No student data is needed.

Hi

Sorry I have not had a chance to send you a copy of the course yet.
I am starting to wonder if it is the course though, because I did some additional checks and found 5 other courses that give the exact same error.

What puzzles me is that these courses are some of the first I created and their grade books did work, and now don't even though nothing has changed in the courses them selves.

Hi Justin.

"due" field was added recently, so maybe those courses worked fine before the upgrade? Anyway, I think it is course related, as it works in some and not in others. I can check when you send me a non working course so I can test.
