alias

alias is used to allow retrieving of the same object by different type hints. E.g. you have configured how to provide A object and want to use it as AProtocol: container.get(A)==container.get(AProtocol).

Provider object has also a .alias method with the same logic.

from dishka import alias, provide, Provider, Scope

class MyProvider(Provider):
    @provide(scope=Scope.REQUEST)
    def get_a(self) -> A:
        return A()

    a_proto = alias(source=A, provides=AProtocol)

Additionally, alias has own setting for caching: it caches by default regardless if source is cached. You can disable it providing cache=False argument.
