Support for multiple @key directives #20
Description
It would be great to have support for multiple @key directives.
For reference, I'm trying to get something like the following working...
Entity service
interface Entity {
entityRef: String!
}
extends type Query {
entity(ref: String!): Entity
}User service
interface Entity {
entityRef: String!
}
type User @key(fields: "id") @key(fields: "entityRef") {
id: ID!
entityRef: String!
name: String
}
extend type Query {
me: User
}The problem is that the first @key directive is functional. The second one is completely ignored (it took me longer than I would like to admit to figure out why this wasn't working 🤦♂️). This means that when the "Entity service" returns a reference to a User, it must provide an id. But the idea for this setup is to let the "User service" figure out how to resolve the User based on the "entityRef".
I'm fairly certain I can work around this for now - simply because my current implementation of generating the "entityRef" involves serialising the ID anyway. But this, I imagine, would be a nice to have for others that don't have that option.
