Hi, I am creating an activity tracker application for recruiters/headhunter.
In my data I have nested the activity underneath each user.
While all of the activity is nested under the user e.g.
I see similar posts for setting the count equal=0 for preventing duplicate entries, but in this case, I want to prevent the User from adding a duplicate day in reference to their own activity.
In other words, multiple duplicate dates in this database are acceptable only if they are entered by different users. How would I go about doing this?
