I'm designing something similar to Admin.Autodiscover() of Django.
The first hurdle that I'm facing is getting the path of the file from which admin.autodiscover() is called, so that I can traverse the apps/libraries in that folder and figure out which models should be kept in admin.
How do I do that?
The Zen of Python says: Explicit is better than implicit.
Why not call it like this: your.autodiscover(__file__), or even your.autodiscover(dirname(__file__)). That way, someone who reads your code doesn't have to look for the magic in your autodiscover function, or look it up in the documentation.
