Prisma

As an example:
```schema.objectType({
  name: 'Item',
  definition(t) {
    t.model.id()
    t.model.name()
    t.model('ItemInstance').data()
  }
})```
Unfortunately the explicit selection of `ItemInstance` doesn't work in this case, as model is not a function as soon as the `name` of the `objectType` matches a Prisma type.

Hey <@UTX14HXRR> :wave:
Do you have a model named `ItemInstance`? If so, then it should work properly.
```schema.objectType({
  name: 'ItemInstance',
  definition(t) {
    t.model.data()
  }
})```
This should be defined in Nexus

Also could you share the link to the docs where this is mentioned :slightly_smiling_face:

Cheers <@UESADRKMY> ! The problem is that I need types from two of my internal/prisma ones, as the external one is a superset of those two internal types. So I need to inherit types from Item and ItemInstance, on an my external/nexus type called Item.

But I just figured I could just rename my internal Item to ItemPrototype.

Then .model becomes a function/callable again, as I don't have an internal
type matching the external one.
