Get absolute path of django app

I am writing a unit test that needs to access an image file that I put in "fixtures" directory right under my django app directory. I want to open up this image file in my test using relative path, which would require me to get the absolute path of the django app. Is there a way to get the absolute path of the django app?

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.)
