Avoid loading the default namespace if not needed (create a lazy loader mode) about dynaconf HOT 4 CLOSED

Hi, I have some suggestions to help solving this issue!

Here is a list of similar issues:

1. Defining default values for some configuration parameters.

2. Allow separation of projects vars via namespace

Please let me know if this was useful:

• Yes, this was useful
• No, this wasn't useful

It was like that before, users needed to call settings.configure before accessing variables.

But some users wanted to have the default namespace for the reasons I commented in #23 (default namespace is needed to define global values)

You change the default namespace name of global namespace using DYNACONF_NAMESPACE env var.

Maybe we can introduce a new object which does not load, for example.

from dynaconf import lazy_settings as settings
settings.namespace('devel')

That new object will be the same, the only difference is that it is not configured automatically and requires settings.namespace to be called once.

That would be awesome! Let me know if I can help :)

I am closing this one year old issue because many things changed since it was created.

Dynaconf exists to avoid the need for such if sys.argv[1] == "prod": kind of code, dynaconf has the goal to make it dynamic by choosing the env based on environment_variables or specific settings passed to LazySettings class.

For your use case the solution is

project/conf.py

from dynaconf import LazySettings
settings = LazySettings(NAMESPACE_FOR_DYNACONF=sys.argv[1])

project/app.py dev

from .conf import settings

settings.current_namespace == 'DEV'

However this case is not recommended, the better by 12 factor apps guide is doing

Your env shell

export NAMESPACE_FOR_DYNACONF=dev

or direct in program call

NAMESPACE_FOR_DYNACONF=dev program/app.py

from dynaconf import settings
settings.current_namespace == 'DEV'

The use of environment variables is better and widely used
