Problem installing and using smart_selects

Smart Selects looked so simple and promising for chained selects (https://github.com/digi604/django-smart-selects).  However, no matter how I install it, it doesn't seem to work.  Here is what I've tried:


Attempt #1 - putting it in django.contrib

Copied the smart_selects folder to /django/contrib/smart_selects

Added "django.contrib.smart_selects" to INSTALLED_APPS in settings.py

But within Django shell I got this error:

>>>  from django.contrib import smart_selects
>>>  smart_selects.urls
AttributeError: 'module' object has no attribute 'urls'



Attempt #2 - installed using pip

I removed the smart_selects folder from /django/contrib  folder (above) and then installed using pip... which put smart_selects in the Python site-packages folder.

But then trying to use smart_selects within urls.py produced an ugly "ImportError: cannot import name simplejson" which suggests smart_selects has some outdated dependencies. (I"m using Django 1.7).



Attemp #3 - putting smart_packages in the root folder of my Django project

When smart_selects is placed here, again I can import smart_selects from the Django shell  but not access smart-selects.urls :

Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import smart_selects
>>> dir(smart_selects)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', 'models']
>>> smart_selects.urls
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'module' object has no attribute 'urls'


Finally it works if i do this:

>>> import smart_selects.urls
>>> smart_selects.urls
<module 'smart_selects.urls' from '/Users/chas/Projects/switch/djangoroot/smart_selects/urls.pyc'>


However, I really don't like putting apps here since they clutter up my own development (and would rather keep 3rd party apps in django/contrib). 

What am I missing about the smart_selects ?
Thank you,

Mike,
