Passing parameters to Resource provider

[ijioio]

It seems that passing parameters to resource is not working for subclasses of resources.Resource and resources.AsyncResource. If run

# poc_task.py
from dependency_injector import resources

class PocTask(resources.Resource):

    def __init__(self):
        print("poc task init")

    def init(self):
        print("poc task start")

    def shutdown(self, some):
        print("poc task finish")

# contianers.py
from dependency_injector import containers, providers
from tasks.poc_task import PocTask

class Container(containers.DeclarativeContainer):

    config = providers.Configuration()
    config.from_yaml(config_path, required=True)

    poc_task = providers.Resource(PocTask)

    # Other dependencies

when PocTask is instantiated it calls the constructor and poc task init is printed. But if you try to add some additional arguments:

# poc_task.py
from dependency_injector import resources

class PocTask(resources.Resource):

    def __init__(self, timeout: int):
        print("poc task init")

    def init(self):
        print("poc task start")

    def shutdown(self, some):
        print("poc task finish")

# contianers.py
from dependency_injector import containers, providers
from tasks.poc_task import PocTask

class Container(containers.DeclarativeContainer):

    config = providers.Configuration()
    config.from_yaml(config_path, required=True)

    poc_task = providers.Resource(PocTask, timeout=config.timeout.as_int())

    # Other dependencies

it complains about calling PocTask constructor:

TypeError: PocTask.__init__() missing 1 required positional argument: 'timeout'

Is it not implemented on purpose, or am I missing something?

As a workaround I've applied trick suggested here:

poc_task = providers.Resource(lambda timeout: PocTask(timeout), timeout=config.timeout.as_int())

[ZipFile]

args/kwargs are passed to the init() method:

class PocTask(resources.Resource):

    def __init__(self):
        print("poc task init")

    def init(self, timeout: int):
        print("poc task start", timeout)

    def shutdown(self, some):
        print("poc task finish")

[ijioio]

poc_task = providers.Resource(lambda timeout: PocTask(timeout), timeout=config.timeout.as_int())

BTW, with this approach Resource stop working as a resource (i.e. no init/shutdown are called)

[ijioio]

args/kwargs are passed to the init() method:

class PocTask(resources.Resource):

def __init__(self):
    print("poc task init")

def init(self, timeout: int):
    print("poc task start", timeout)

def shutdown(self, some):
    print("poc task finish")

Thank you!
