if I found myself with 50 messages in the model update I'd take as a sign
that I need to abstract things more.
Regarding the update of nested attributes, I agree that there is not a good
way to do it, hence this thread. =)

Maybe something like this could work for you:
case lol of
Submit locationList ->
let
results =
validateEditLocationListForm model.locationListData
( newLocationListData, cmd ) =
if List.length results > 0 then
( { locationListData | errors = Just results },
Cmd.none
)
else
( { model | locationListData = data },
postUpdateLocationList locationListData locationList )
in
( { model | locationListData = newLocationListData }, cmd )
