Dict provider from configuration file with additional items

[mighelone]

I wonder if it is possible to read a generic dictionary from a config file (i.e. yaml), and then add new items to the existing dictionary.

For example, I have the following yaml file:

conf:
   a: 1
   b: 2

In the container:

@dataclass
class MyClass
    conf: dict[str, any]

class Container(containers.DeclarativeContainer):
    config = providers.Configuration()
    
    my_class_factory = providers.Factory(MyClass, config.conf)


container = Container()
container.config.from_yaml("config.yaml")
obj = container.my_class_factory()

This work, creating an object with the conf dictionary defined in the yaml file.
However, I want to add other items to the conf dictionary not defined in the file.
I only manage to do in this way:

@dataclass
class MyClass
    conf: dict[str, any]

class Container(containers.DeclarativeContainer):
    config = providers.Configuration()
    
    my_class_factory = providers.Factory(MyClass)


container = Container()
container.config.from_yaml("config.yaml")
obj = container.my_class_factory(conf={**container.config["conf"], "c": 67})

Is there a better way of doing it?
