I'm working wit Moodle 3.x.
I need to generate an excel file with all students and their feedback data (or grader data, I think) by cron. I have installer myfeedback plugin, but this doesn't have any cron function or any "get_all_students_and_data" function. Do you know how could I generate this information (I know how to create a file with all information, no problem)? I'm thinking about an array of all students ID and a foreach instruction in which I could call the functions of myfeedback plugin, but I don't know if this is possible and if I could do this.
