Injecting a list of dependencies #243
Description
Hi, thanks for the nice and well documented framework! There is one point I am currently missing. Let's say I have a class that depends on a list of other classes, I want to achieve something like the following example (written in Python 3.7)
from typing import *
from dependency_injector import containers, providers
class B:
def __init__(self, val: int):
self.val = val
def __repr__(self):
return f"B({self.val})"
class A:
def __init__(self, bs: List[B]):
self.bs = bs
def __repr__(self):
return f"A({self.bs})"
def main() -> None:
class IocContainer(containers.DeclarativeContainer):
bs = providers.Provider(
list,
providers.Factory(B, 1),
providers.Factory(B, 2),
)
a = providers.Factory(
A,
bs,
)
container = IocContainer()
print(container.a())
if __name__ == "__main__":
main()However, using a list of providers seems not to be possible, as the list constructor only takes a single argument, but directly instantiating a list of providers will not instantiate the providers.
What would be the way to go to inject a list of dependencies.
