Dynamic object injector

[tcpdcp22]

Hello.

1. I'm trying to create a Controller object that I expect to be taken from the container to the initializer of the SomeEntity class and so that it is built automatically from the arguments that are next to it (arg1, arg2) in the initializer of the SomeEntity class. I would also like to pass these arguments to the next object (SomeCls) inside the Controller - can I do such a chain?
   What should I substitute for the '???' signs? Tried dynamic container but didn't work

2. Why don’t I see the difference between the @Inject decorator attached to the initializer of the SomeEntity class and without this decorator? All classes are in different modules

from dependency_injector import providers, containers
from dependency_injector.wiring import inject, Provide


class SomeCls:

    def __init__(self, arg1, arg2):
        self.arg = arg1
        self.arg2 = arg2


class Controller:

    def __init__(self, arg1, arg2, some_cls: SomeCls):
        self.a = arg1
        self.b = arg2
        self.cls = some_cls


class Container(containers.DeclarativeContainer):

    controller = providers.Factory(
        Controller,
        arg1=???,
        arg2=???,
        some_cls=providers.Factory(
            SomeCls,
            arg1=???,
            arg2=???,
        )
    )


class SomeEntity:

    @inject
    def __init__(self, arg1, arg2, controller: Controller = Provide[Container.controller]):
        self.arg = arg1
        self.arg2 = arg2
        self.controller = controller
