Using of configuration provider with some singleton providers #313
Description
Hi, I've a problem with wiring function and I don't understand where I'm wrong.
My classes are that:
ConfigurationContainer.py
from dependency_injector import containers, providers class ConfigContainer(containers.DeclarativeContainer): config = providers.Configuration()DependencyContainer.py
from dependency_injector import containers, providers from src.DialogflowInteraction import DialogflowInteraction from src.QA.ContextRetriever.VeryBasicContextRetriever import \ VeryBasicContextRetriever from src.QA.QA import QA class BotDependencyFactory(containers.DeclarativeContainer): verybasiccontextretriever = providers.Singleton(VeryBasicContextRetriever) q_a = providers.Singleton(QA) dialogflowinteraction = providers.Singleton(DialogflowInteraction)Bot.py
import logging from uuid import uuid1 import sys from dependency_injector.wiring import Provide from src.ConfigurationContainer import ConfigContainer from src.DependencyContainer import BotDependencyFactory class Bot(): def __init__( self, threshold=Provide[ConfigContainer.config.general.threshold.as_float()], q_a = Provide[BotDependencyFactory.q_a], context_retriever = Provide[BotDependencyFactory.verybasiccontextretriever], dialogflowinteraction = Provide[BotDependencyFactory.dialogflowinteraction] ): self.threshold = threshold self.QA = q_a self.context_retriever = context_retriever self.df_bot = dialogflowinteractionapp.py
import logging import os import sys from src.ConfigurationContainer import ConfigContainer from src.DependencyContainer import BotDependencyFactory from src.bot import Bot def configure_env(): logging.basicConfig(level=logging.INFO) config = ConfigContainer() config.config.from_ini('config.ini') logging.info('configuration completed') return config if __name__ == '__main__': config = configure_env() config.wire(modules=[sys.modules[__name__]]) logging.info('Configuration container wired successfully') bot_dependency_factory = BotDependencyFactory() bot_dependency_factory.wire(modules=[sys.modules[__name__]]) bot = Bot() When I try to run main method returns this exception
