Is there an alternative way to select certain fields without using Ash.Query?

Currently I'm using it like:

MyApp.Domain.Resource
|> Ash.Query.limit(1)
|> Ash.Query.select([:slug])
|> Ash.read!()

MyApp.Domain.Resource
|> Ash.Query.limit(1)
|> Ash.Query.select([:slug])
|> Ash.read!()

But how am I going to use select in inside of read?:

actions do
  read :read do
    ???
  end
end

actions do
  read :read do
    ???
  end
end

Few of the attributes are public, include :slug

prepare build(select: [:slug]) but also

prepare fn query, _ ->
  Ash.Query.select(query, [:slug])
end

prepare fn query, _ ->
  Ash.Query.select(query, [:slug])
end

I'd highly recommend reading the action guides, for each action type You can do a whole lot with actions

Ah! I can see now where you were saying 🙏🏾 thanks for the advice!!!
