How to associate foreignkey data in django 3.0 - django

Question

How do I pull all of the users and put their full name into a context that I pass to a view? My view currently pulls all of the filtered rows and I want to replace the id of the user with their full name before I pass the context to the view. This is probably very simple, but I can't seem to make it work. The field trigger_caused_by holds the id of the user that made the change that fired the trigger.
