Get absolute path of django app

În newer versions of Django (I don't know when it started, I assume it's there for many years now), the default settingy.py contains an entry

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

which you can use by importing the settings file like this

import os    
from my_project_name.settings import BASE_DIR

os.path.join(BASE_DIR, ...)

Python modules (including Django apps) have a __file__ attribute that tells you the location of their __init__.py file on the filesystem, so

import appname
pth = os.path.dirname(appname.__file__)

should do what you want.

In usual circumstances, os.path.absname(appname.__path__[0]), but it's possible for apps to change that if they want to import files in a weird way.

(I do always do PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__)) in my settings.py, though -- makes it easy for the various settings that need to be absolute paths.)

Normally, this is what I add in my settings.py file so I can reference the project root.

import os.path

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))

This method will get the directory of any python file.

So the accepted answer usually works fine. However, for

• namespace packages with multiple paths, or
• apps which explicitly configure their paths in the config,

their intended path may not agree with the __file__ attribute of the module.

Django (1.7+) provides the AppConfig.path attribute - which I think is clearer even in simple cases, and which covers these edge cases too.

The application docs tell you how to get the AppConfig object. So to get AppConfig and print the path from it:

from django.apps import apps
print(apps.get_app_config('app_label').path)

Edit: Altered example for how to use get_app_config to remove dots, which seems to have been confusing. Here are the docs for reference.
