I'm reading up that most people do from django.conf import settings
but I don't undertstand the difference to simply doing import settings
in a django project file. Can anyone explain the difference?
import settings will import the first python module named settings.py found in sys. path . Usually (in default django setups) it allows access only to your site defined settings file, which overwrites django default settings ( django. conf.
Default settings These defaults live in the module django/conf/global_settings.py .
settings.py is a core file in Django projects. It holds all the configuration values that your web app needs to work; database settings, logging configuration, where to find static files, API keys if you work with external APIs, and a bunch of other stuff.
In your python settings file, you have to import our LazySetting class located in python_settings. Only the first time you call this property, the HeavyInitializationClass will be instantiated and the *args and **kwargs parameters will be passed. Every time you call this property the same instance will be returned.
import settings
will import the first python module named settings.py
found in sys.path
. Usually (in default django setups) it allows access only to your site defined settings file, which overwrites django default settings (django.conf.global_settings
).
So, if you try to access a valid django setting not specified in your settings file you will get an error.
django.conf.settings
is not a file but an object (see source) making an abstraction of the concepts, default settings and your site-specific settings. Django also does other checks when you use from django.conf import settings
.
You can also find it in the django docs.
Hope this helps.
from django.conf import settings
is better option.
I use different settings files for the same django project (one for "live", one for "dev"), the first one will select the one being executed.
