How to @override a field from another subgraph using original value from that subgraph

[kindermax]

My case is: I have two subgraphs

products with type Product

type Product @key("id") {
  id ID!
  name: String!
}

and translations where I am trying to override name field

type Product @key("id") {
  id ID! @external
  name: String! @requires("name") @override("products")
}

The problem is - I do not know how to tell Gateway/Router that I need a field name from products subgraph and then I will use it in translations subgraph to generate a new value based on original value.

For example: if name field from products subgraph is IPhone, I need to modify it for example like: IPhone (EN).

Is it possible to achieve what I am trying to do ?

Hello 👋
You cannot do it with the same field. You could use extra inaccessible field though

// products
type Product @key("id") {
  id ID!
  privateName: String! @inaccessible // <- this will not be available in the public API
}

// translations
type Product @key("id") {
  id ID!
  privateName: String! @external @inaccessible
  name: String! @requires("privateName")
}

Ok, that's a solution, thank you. Is it any chance that in the future federation will allow it to be possible to achieve this as I described ?

👋 As the old saying goes, never say never.... but it seems very unlikely that we will be changing the @override behavior anytime soon.
