How to resolve models in CUD operations not on PK but on UUID?

Question

The default CUD operation in srawberry_django identifies the model to be mutated by the model's id (the database's id column, which is the Primary Key). How can I change this behavior to point to a column's/model's UUID without overriding strawberry_django.mutations.update method?

In simple terms, how to do a search on a field that is not id/PK in strawberry-graphql-djang without mending update method?

Can you share your graphql type declaration? I think you can set the field class like ```id: auto = strawberry.django.field(field_name='model_uuid')``` — Oluwafemi Sule, Aug 26 '23 at 12:57
Thanks @OluwafemiSule I have tried it, and it doesn't work. I share the way with my answer :) — Lukasz Dynowski, Aug 26 '23 at 19:46

At the moment of strawberry-graphql-django v0.16.0 it's not possible to do so! The reason is the implementation of get_pk method.

def get_pk(data: dict[str, Any],) -> strawberry.ID | relay.GlobalID | Literal[UNSET] | None:
    pk = data.pop("id", UNSET)
    if pk is UNSET:
        pk = data.pop("pk", UNSET)
    return pk

As you can see, this method assumes that the model identifier is id or pk ONLY!
