Getting a dependency group from a config string

[Skr1pee]

I’m trying to get a group of dependencies based on a string in the configuration. However, no matter what I try—using the built-in providers and selectors for this—in the final class I still end up with a provider instead of a dependency. What am I doing wrong? (An example is shown in the code below.)

class SomeValue():
    ...


class SomeClass():
    def __init__(self, v) -> None:
        assert not isinstance(v, Factory)  # Goal: pass it
        ...


class SomeValueContainer(DeclarativeContainer):
    value = Factory(SomeValue)


class MasterContainer(DeclarativeContainer):
    config = Configuration()

    value = Selector(
        config.x,
        b=Container(SomeValueContainer)
    )

    factory = Factory(SomeClass, v=value.provided.value.provided)


container = MasterContainer()
container.config.from_dict({"x": "b"})
container.factory()
