Union of types as attribute type in strawberry input class

[eddysen]

Hello, can any one show me how i can manage to use Union of types as type for attribute in strawberry input class ?
I need to do something like this :

@strawberry.input
class DesignationClientInType:
	designation : Union[ProduitClientInType, KitClientInType]

when trying it's telling me that Union for ProduitClientInType is not supported because it is an Input type

Hi @eddysen! Unfortunately, this is not supported by the GraphQL spec :(

There's a potential alternative which is called oneOf but that hasn't been implemented yet in the spec, but it is easy to implement by hand: https://stepzen.com/blog/coming-soon-to-graphql-the-oneof-input-object

maybe we can implement it in future if there's enough demand 😊

[patrick91]
