Anyone have any luck? I'm getting this with custom objects still on latest version

from pytest-factoryboy.

nowadays pytest-factoryboy gives this warning:

 Using a <class 'list'> as model type for <ListFactory for <class 'list'>> is discouraged by pytest-factoryboy, as it assumes that the model name is 'list' when using it as SubFactory or RelatedFactory, which is too generic and probably not what you want.
   You can giving an explicit name to the model by using:
   model = named_model(list, "Foo")
        factory_class = <class 'factory.base.ListFactory'>
        model_cls  = <class 'list'>
        model_name = 'list'

Try that out, it should probably fix your issue.

anyway, this is the most correct way I can think of to fix the initial issue posted by @sanchez-escobar:

import factory
from pytest_factoryboy import register


class ClassA:
    def __init__(self, val):
        self.val = val


class ClassB:
    def __init__(self, arr):
        self.arr = arr


class ClassAFactory(factory.Factory):
    """TestClassA factory."""

    class Meta:
        model = ClassA

    val = "test_value"


class ClassBFactory(factory.Factory):
    """TestClassB factory."""

    class Meta:
        model = ClassB

    class Params:
        arr_0 = factory.SubFactory(ClassAFactory)

    arr = factory.LazyAttribute(lambda o: [o.arr_0])


register(ClassAFactory)
register(ClassBFactory)


def test_example_a(class_a):
    """
    Assert that the nested list is properly tested
    """
    assert class_a.val == "test_value"


def test_example_b(class_b):
    """
    Assert that the nested list is properly tested
    """
    assert len(class_b.arr) == 1
