in settings.py add something like this:
MY_LOG_PATH = os.path.join(os.path.abspath(__file__), "mylogs")
in your view.py add this:
from django.conf import settings
# access log path.
print(settings.MY_LOG_PATH)
You can also do per app settings, go around github and check out examples from
existing projects. but here is the jist of it.
in a settings.py file that's in a app dir:
from django.conf import settings
def get(key, default):
return getattr(settings, key, default)
MYAPPPATH = get("MYAPPPATH", os.path.abspath(__file__)
This allows you to keep a setting in your app and override that setting with
the project settings. The caveat here is that these settings aren't available
through django.conf.settings if they aren't listed in the project settings.py
file. You have to import the app settings file specifically. The get() acts as
a middleman between your local app settings and the ones in the project
settings file By calling getattr() on the main settings it can retrieve the
setting attr or use the default if the settings attr isn't defined in the
project settings.
example usage:
from myapp import settings as myapp_settings
# if MYAPPPATH is defined in the project settings.py file,
# it'll get that value if not use the default in the apps setting file.
print(settings.MYAPPPATH)
If you're still stuck on how this works, the missing pieces are in python
itself and how it treats each .py as an importable module. [2]
