Core Data Relationship from One Entity to Multiple Entities

Question

I have a scenario of this data model:

• Plan has user relationship

• Activity also have user relationship

So in User entity, I created:

• Relationship of this userID to Activity's user

but how could I add relationship of userID to Plan's?

---

I read that I need to create 2 children entities of User. Is this the best practice?

Maybe I can create this 2 children entities of User:

• UserPlan
• UserActivity

But how can I refer the inherited userID of each children in relationship?

Answer 1

Rename relationships in User to activity and plan and connect accordingly.
