Problem installing and using smart_selects

[Michael Ackary]

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has some outdated dependencies.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 "", line 1, in 
AttributeError: 'module' object has no attribute 'urls'


Finally it works if i do this: 

>>> import smart_selects.urls
>>> smart_selects.urls



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,

Check the git repo, the issues page, one of the issues (I think the 4th)
says that in the tittle, Can not import simple json.

You basically have to install it with pip but from the git branch, because
they haven't updated pypy yet

You don't ever want to do this. The "django.contrib" module is for
modules distributed with Django; it's not a place to add your own
additional code.

It also doesn't work, because smart_select expects to be able to import
itself as "smart_select", not as "django.contrib.smart_select."

This is the right way to make use of third-party code. The problem here,
as you say, is just that smart_select has some outdated code. It's
actually been fixed in master, just not posted to PyPI yet, so you'll
need to install it directly from git, as mentioned in the fourth comment
here: https://github.com/digi604/django-smart-selects/issues/70

The difference between the "doesn't work" and "works" versions here
doesn't have anything to do with how you've installed the code, it's
simply how submodule imports work in Python. Submodules are never
automatically imported unless you import them explicitly.

Yes, this installation technique will work fine, but it clutters things
up and makes it harder to upgrade in the future.
