Where should non-database global variables (or global data) be placed?

Using Django
1

For example, I have a config json file that doesn’t need to modify at all, but views may need to read it:

Core_config:

{
  "timeout":300,
  "some_url":"https://(some url)"
  .
  .
  .
}

My question is, where should I put the variable of the global data?

Option 1 : place at AppConfig:

#apps.py
class CoreAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'Core'
    config = None

    def ready(self):
        try:
            with open(os.path.join(apps.get_app_config(self.name).path, self.name + '_config.json'), 'r', encoding='utf-8') as f:
                config_str = f.read()
            self.config = json.loads(config_str)
        except Exception as e:
            print('open ' + self.name + '_config.json failed')

#views.py
def some_api(request):
    some_url = apps.get_app_config("Core").config["some_url"]
    .
    .
    .

I know it is not good for a view to access AppConfig directly, so I have another options:

Option 2 : place it at a new class:

#myconfig.py
class MyConfig:
  core_config = None

#apps.py
class CoreAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'Core'
    config = None

    def ready(self):
        try:
            with open(os.path.join(apps.get_app_config(self.name).path, self.name + '_config.json'), 'r', encoding='utf-8') as f:
                config_str = f.read()
            MyConfig.core_config = json.loads(config_str)
        except Exception as e:
            print('open ' + self.name + '_config.json failed')

#####################################################################

#views.py
def some_api(request):
    some_url = MyConfig.core_config["some_url"]
    .
    .
    .

Which one is better? Or is there any better options other than the 2 options above?

I would default to extending settings.py as it’s just plain python:

settings.py

SOME_URL = "https://(some url)"
MY_TIMEOUT = 300

views.py

from django.conf import settings

def my_view(request):
    url = settings.SOME_URL

With settings being plain python you have a dict, list or classes etc…

There are also packages like django-constance which allow editing some settings at runtime if you want.
