Gqlgen: Type as field in a model, what to do?

[frederikhors]

If I have a model like this:

type Player struct {
  Kind  PlayerType
}

type PlayerType int

const (
  Zombie PlayerType = iota
  Human
  Dog
)

and a schema like this:

type Player {
  kind: Int!
}

it generates method in resolver for Kind:

func (r *playerResolver) Kind(ctx context.Context, obj *Player) (int, error) {
  panic(fmt.Errorf("not implemented"))
}

but PlayerType is just a new type based on int.

How to fix this?

I need to write something in config.yml?

versions

• gqlgen version? v0.11.3
• go version? go1.14.3 windows/amd64
• dep or go modules? go mod

I think I can jump in on this (and happy to be told that this isn't quite correct).

func (r *playerResolver) Kind(ctx context.Context, obj *Player) (int, error) {
  return int(obj.Kind), nil
}

Because PlayerType is a specific type based on int it still needs to be cast as one.

One solution would be to create a scalar type on the graphql side and then bind that to your go type.

see https://github.com/99designs/gqlgen/tree/master/example/scalars for examples of this.

That's probably a neater solution right there @lwc!
