It's been a while since I last posted a doubt about how to do something with moodle and in the past you have all been extremelly helpful. I hope this time will be the same!
So, the idea I have in mind is that I want a database activity in which users can add a record. Each record contains, as one of it fields, a file. I would want these files to be accessible from the File Picker, so that, for example, a teacher could pick it (or link it by creating an alias) to add it somewhere else in Moodle, just like he would be able to do it with a dropbox, webdav, google drive or whatever repository if the appropiate repository plugin is enabled.
Is there a way to do this?
