a list-type environment variable contains tuple-type elements

[tombreit]

Perhaps related: I'm trying to store the Django ADMINS [1] setting via environs and did not manage to find a representation of the desired setting (a list of two-tuples):

[('John', '[email protected]'), ('Mary', '[email protected]')]

What I've tried:

# .env
ADMINS="(Doe,doe@fqdn),(Joe,joe@fqdn)"

...but this translates to

 ['(Doe', 'doe@fqdn)', '(Joe', 'joe@fqdn)']

My workaround

(stolen from https://django-environ.readthedocs.io/en/latest/tips.html#nested-lists)

# .env
DJANGO_ADMINS=Blake:[email protected],Alice:[email protected]

# django settings.py
ADMINS = [x.split(':') for x in env.list('DJANGO_ADMINS')]

This is a workaround:

from environs import Env
import ast

env = Env()
env.read_env()

print(ast.literal_eval(f"[{env.str('SOME_CONFIG_LIST')}]"))

With the .env file:

SOME_CONFIG_LIST=(1,2,3),(2,3,1)
