Unless I'm doing something wrong (very possible!) it doesn't seem like the @strawberry.experimental.pydantic.type annotation/function works with postponed Pydantic annotations...

class User(BaseModel):
    id: int
    first_name: str
    last_name: str
    email: str
    date_joined: datetime.datetime
    organization: "Organization"


class Organization(BaseModel):
    id: int
    name: str
    owner: User


User.update_forward_refs()


@strawberry.experimental.pydantic.type(model=User, fields=[
    'id',
    'first_name',
    'last_name',
    'email',
    'date_joined',
    'organization',
])
class User:
    pass


@strawberry.experimental.pydantic.type(model=Organization, fields=[
    'id',
    'name',
    'owner',
])
class Organization:
    pass
