I have two collections, call them ‘parents’ and ‘children’. Each ‘child’ refers to one ‘parent’.
- parent_1
- child_A
- child_D
- parent_2
- child B
- child C
One way to handle this is to publish / subscribe both collections and then filter in the renderChildren method of each component (or the renderOneParent method and pass a filtered list), but this seems like it could involve O(n^2) filtering as parent and child get large. Is there a sensible way to make the component that renders each parent subscribe to a filtered set of children, or am I approaching the problem in the wrong way?
