Using "factories as fields" for collection types

[Kilo59]

I want to be able to extend the current examples for factories as fields for collection type fields, but currently this seems impossible to do while preserving the existing build parameter delegation.

Is this possible?

https://polyfactory.litestar.dev/latest/usage/fields.html#factories-as-fields

I've modified the existing example to add a pets: list[Pet] field

from dataclasses import dataclass
from datetime import date, datetime
from enum import Enum
from typing import Any, Dict, List, Union
from uuid import UUID

from polyfactory.factories import DataclassFactory


class Species(str, Enum):
    CAT = "Cat"
    DOG = "Dog"


@dataclass
class Pet:
    name: str
    species: Species
    sound: str


@dataclass
class Person:
    id: UUID
    name: str
    hobbies: List[str]
    age: Union[float, int]
    birthday: Union[datetime, date]
    pet: Pet
    pets: List[Pet] # changed from pet to pets
    assets: List[Dict[str, Dict[str, Any]]]


class PetFactory(DataclassFactory[Pet]):
    name = lambda: DataclassFactory.__random__.choice(["Ralph", "Roxy"])


class PersonFactory(DataclassFactory[Person]):
    pet = PetFactory
    pets = PetFactory # is there something I can do to tell PolyFactory this should be a list? 
    # pets = PetFactory.batch(1) <- this works but is inflexible


def test_subfactory() -> None:
    # I want to be able to customize the PetFactory and still pass build parameters to it
    person_instance = PersonFactory.build(pet="this_is_fine", pets="this_breaks")

Does https://polyfactory.litestar.dev/latest/reference/factories/base.html#polyfactory.factories.base.BaseFactory.__set_as_default_factory_for_type__ work for this use case?
