providers.Configuration(ini_files=...) doesn't seem to work

[shimat]

Hi,
when using providers.Configuration(ini_files=...), the ini file does not seem to be loaded. But from_ini works fine.

My environment: Windows 11, Python 3.10.1, dependency-injector = "4.38.0".

# config.ini
[A]
xxx = foo
yyy = bar

# pytest example
from pathlib import Path
from dependency_injector import providers

def test_configuration():
    assert Path("config.ini").exists() is True

    config1 = providers.Configuration()
    config1.from_ini("./config.ini", required=True)
    assert config1() == {'A': {'xxx': 'foo', 'yyy': 'bar'}}  # OK

    config2 = providers.Configuration(ini_files=["./config.ini"])
    assert config2() == {'A': {'xxx': 'foo', 'yyy': 'bar'}}  # Failure

"""
>       assert config2() == {'A': {'xxx': 'foo', 'yyy': 'bar'}}
E       AssertionError: assert {} == {'A': {'xxx':...'yyy': 'bar'}}
E         Right contains 1 more item:

E         + {}

Hi @shimat ,

Thanks for reporting the issue, I'll take a look.

Following up after quick research. To make the second example work properly there is an extra method that should be called config2.load(). See the following example:

from pathlib import Path
from dependency_injector import providers


def test_configuration():
    assert Path("config.ini").exists() is True

    config1 = providers.Configuration()
    config1.from_ini("./config.ini", required=True)
    assert config1() == {'A': {'xxx': 'foo', 'yyy': 'bar'}}  # OK

    config2 = providers.Configuration(ini_files=["./config.ini"])
    config2.load() #  <-------------- call this to load all provided configuration
    assert config2() == {'A': {'xxx': 'foo', 'yyy': 'bar'}}  # Failure


if __name__ == "__main__":
    test_configuration()

Container does this automatically when you create a container instance.
@shimat could you provide more information about your use case? Do you use configuration provider outside of a container?

Thanks for the information. I just tried the code below and it didn't cause any problems. When I tried almost the same code before it looked like a failure, maybe there was some mistake on my part. Anyway, thank you very much.

from dependency_injector import containers, providers

class Container(containers.DeclarativeContainer):
    config1 = providers.Configuration()
    config1.from_ini("config.ini", required=True)
    config2 = providers.Configuration(ini_files=["config.ini"])

if __name__ == "__main__":
    container = Container()
    print(container.config1())  # {'A': {'xxx': 'foo', 'yyy': 'bar'}}
    print(container.config2())  # {'A': {'xxx': 'foo', 'yyy': 'bar'}}
