[RFC] Load multi environment settings from dictionary

I have researched documentation and also some source code, but I can’t find any possibility to load configuration from a dictionary. I need this for testing, as we define settings in the test code itself. Generally it would be good to have a wrapper where everything smart and environment dependent is disabled (I know about DynaconfDict, but this doesn’t quite fulfill my needs), especially the dependency on files and env vars as those can cause quite a few issues as I experienced.

Up to now i used DotMap to achieve similar interface, but at nested levels merging is becoming an issue, thus I’m now trying to decrease prod / test parity by also applying dynaconf in tests.

I am aware that it I can just pass the dict like Dynaconf(**json_config), but this results in issues with environments and so on.

Am I missing an option?

I just fund a workaround, which is definetly not nice but does what I need:

from dynaconf import Dynaconf
from dynaconf.loaders import json_loader
from dynaconf.loaders.base import BaseLoader


def load(obj, env=None, silent=True, key=None, filename=None):
    class CustomLoader(BaseLoader):
        def load(self, filename=None, key=None, silent=True):
            # settings as dict from outer scope
            self._load_all_envs({"asdf.json": settings}, silent, key)

    loader = CustomLoader(
        obj=obj,
        env=env,
        identifier="json",
        extensions=None,
        file_reader=None,
        string_reader=None,
    )
    loader.load(
        filename=filename,
        key=key,
        silent=silent,
    )

json_loader.load = load

settings = Dynaconf(settings_file="settings.json", loaders=[], environments=True)

Vulnerable to internal interface changes though.
