I'm designing the app model (not necessarily the @Entity-ies) with the help of the room docs. The thing is that in one-to-many scenario the parent knows nothing about the children plus every child has only an ID of the parent.
However I absolutely have to have an Ad as well as the list of application results (not just ids, whole objects) in AdEntry. Is it possible to do so in Room?

[Bruno_]

every example I've seen out there have just primitives (I mean string, int etc) in the @Entity

One solution would be to separate my model classess (diagram) from the actual @Entity-ies and just convert stuff on the go, but I would have to make a couple of additional database calls so this approach isn't very scalable

if it comes to the app architecture, it looks like this: (still working on it tho, it's not complete and may contain some bugs)

also I can't just annotate stuff with @Embedded as I need these things to be in separate tables

uhh so thanks to this blog now I know that I can just use @Relation in case of AdEntry -- ApplicationResult relation, still don't know what about the AdEntry -- Ad

[Bruno_]

in other words, I want Ad to be embedded but in a separate table

I think you need to create a table Ad like you diagram shows.

I mean at the end of the day Room is just a ORM so it does convert to SQLite and its impossible to include a table as a row in a relational db. There is a concept of virtual table in SQLite but its different from table. It behaves like View
