Delete mutation in Django GraphQL

Question

The docs of Graphene-Django pretty much explains how to create and update an object. But how to delete it? I can imagine the query to look like

mutation mut{
  deleteUser(id: 1){
    user{
      username
      email
    }
    error
  }
}

but i doubt that the correct approach is to write the backend code from scratch.

Answer 1

Something like this, where UsersMutations is part of your schema:

class DeleteUser(graphene.Mutation):
    ok = graphene.Boolean()

    class Arguments:
        id = graphene.ID()

    @classmethod
    def mutate(cls, root, info, **kwargs):
        obj = User.objects.get(pk=kwargs["id"])
        obj.delete()
        return cls(ok=True)


class UserMutations(object):
    delete_user = DeleteUser.Field()
