How to handle circular dependency [non-string keys for Dict provider] #327
Description
so i have handler class to be injected by container to get repositry object
service/handler.py
from ... import Container
from dependency_injector.wiring import inject, Provide
from .rating_repository import RatingRepository
from ..domain.commands import SaveRating
from ..domain.models import RunnerRating
class CommandHandler:
# Dep Injector
@inject
def __init__(self, rating_repo: RatingRepository =
Provide[Container.repo.rating]):
self.rating_repo = rating_repo
this handler is included in messagebus module like this
service/messagebus.py
from .handler import CommandHandler
Message = Union[Command, Event]
logger = logging.getLogger(__name__)
command_handler = CommandHandler()
COMMAND_HANDLERS = {
SaveRating: command_handler.save_rating,
}
class MessageBus:
def __init__(self):
pass
# rest methods...
but i also add MessageBus class on container that make me include service/messagebus.py to container.py
container.py
from .runner_rating.service import messagebus
'''
Dependency injector for application
'''
class MessageBusContainer(containers.DeclarativeContainer):
bus = providers.Container(
messagebus.MessageBus
)
when i run the app, it shows ImportError on container.py because i imported messagebus and inside it there is a handler object that import container.py
what should i do to solve this? because message bus will be injected to other module in future
