How can a list element in a Configuration provider be injected?

Hello,

I have quite a nested configuration file that contains a lot of lists. I would like to inject a specific element into a provider, which would look like:

config = providers.Configuration(defaults={'index': 0, 'items': list('a', 'b', 'c')})

foo= providers.Factory(Foo, item=config.items[config.index])

However, I was prompted:

TypeError: 'dependency_injector.providers.Configuration' object is not subscriptable

Anyone has idea about this? Thank you.

@clifflau1120 ,

I didn’t sleep well after was unable to implement providers.Factory(Foo, option1=config.items[config.target].option1). I would like Dependency Injector to handle this case. I also didn’t like the internals of Configuration provider, so:

• I’ve completely re-designed the internals of Configuration provider.
• It now handles config.items[config.target].option1 use case. See example: https://github.com/ets-labs/python-dependency-injector/blob/master/examples/providers/configuration/configuration_itemselector.py

Feature is available in Dependency Injector 3.26.0.
