Good way to deal with Persistent's Entity?

Im adapting to Yesod Persistent. Thus my old Game type becomes "[Entity](https://hackage.haskell.org/package/persistent-2.8.1/docs/Database-Persist-Types.html#t:Entity) Game" that is constructed as "Entity GameId Game" where type GameId = Key Game (or something like that).

ive managed to make stuff work by adding a wrapper that can be incorpoarated in elm-bridge, but it feels clumsy

`data Ent a b = Ent { _key :: a, _val :: b } deriving (Show,Generic)`

Incase you are familiar with Persistent, how would one incorporate encoding of (nested) entity types in elm-bridge.

trying to get :

`deriveBoth defaultOptions { fieldLabelModifier = drop 1} ''PS.Entity`

..to compile gives :

`Can't derive this sum: ForallC [] [AppT (ConT Database.Persist.Class.PersistEntity.PersistEntity) (VarT record_7566047373982557936)] (RecC Database.Persist.Class.PersistEntity.Entity [(Database.Persist.Class.PersistEntity.entityKey,Bang NoSourceUnpackedness NoSourceStrictness,AppT (ConT Database.Persist.Class.PersistEntity.Key) (VarT record_7566047373982557936)),(Database.Persist.Class.PersistEntity.entityVal,Bang NoSourceUnpackedness NoSourceStrictness,VarT record_7566047373982557936)])`
