I have a Fulcro data modeling question: What are people’s approach for modeling an entities that have different “types” but the same ident. I contrived example would be a “Vehicle” type, that might be a “Car” with car-like attributes, or a “Truck” with “truck” attributes (and some overlaps), but the same vehicle/id ident I know Fulcro has Union queries, but these require the idents of the components to be unique. In the example I gave above, it might be worth changing the idents to be unique, but frequently that feels like the wrong choice in my actual data model, and I find myself having to make some mega query thats the union of everything i might be constructing, and a lot of custom logic to reset attributes when changing “types” in forms, etc. Am I just modeling these things wrong and should be aiming for unique idents?
