Factory boy - related factory retrieval

.py

# Models
class Foo(Model):
    text = models.CharField(max_length=64, blank=False)

    
class Bar(Model):
    text = models.CharField(max_length=64, blank=False)
    
# Factories    
class FooFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = Foo

    text = factory.Faker('pystr')
    
class BarFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = Bar

    text = factory.Faker('pystr')
    
    
class FooWithBarFactory(FooFactory):
    bar = factory.RelatedFactory(BarFactory, text=factory.SelfAttribute('..text'))
    

# How I might retrieve related factory now:
foo = FooWithBarFactory()
bar = Bar.objects.get(text=foo.text)

# How I'd like to retrieve related factory - Obviously doesn't work as things stand
foo, bar = FooWithBarFactory()

# or ?
foo.bar = FooWithBarFactory()
