"Doesn't work" is not very informative. Does it raise an error? Do
nothing? What is the difference between "works" and "doesn't work" in
this case.
By the way, if it is a circular import issue, as Marty surmises, one
solution is to not "import *". Just do
from app_name import shortcut, utilities
That avoids almost all circular import issues, since it loads the
modules' names into sys.modules, but doesn't try to do any name
resolution inside them. Only when you actually *use* the functions
inside them (which is hopefully inside your own functions in models.py
and not at the top-level of that module) will Python need to do name
resolution and by that stage all the importing will have finished. There
are ways to trip up even this process, but that's usually a sign of
unfortunate design and it would be time to factor out the common pieces.
