Question

I have several applications in my django project. I would like to re-use some of the functions across all of my apps. I created a new app, and added a custom functions.py to it. Trying the following:

from myNewApp import *
from myNewApp import functions

I get NameError: global name xxx is undefined

Am I omitting something important?

How would you recommend I solve the problem of re-using code across multiple apps?

Thanks,

Imagine that you have a project called commons where you store all the code you want to share. And then you want to use the code of commons in a project called foo. Imagine that you have the follow directories:

/home/shared/commons.py
/home/tim/projects/foo.py

The commons.py have this content:

def say_hello():
    return "Hello World!"

If you want to be able to import the module commons in your file test.py put in this file:

import sys
sys.path.append("/home/shared/")

import commons
print commons.say_hello()

And it will print “Hello world!”.
