Re: Hey! I'm recieving an index error when trying to import models, and I can't figure out why.

Stick a print statement between lines 91 and 92 to show you model_module.__name__ .

(or use pdb if you're comfortable with it).  My best guess is that the split() is returning a
list of one item.  That is, that there is no '.' in model_module.__name__ .  Thus an index
of -2 failss: there is no penultimate item.

At least for the time when it gets the exception.  That is, you may get many lines printed,

but the last one before the exception won't have a '.'

I just tried this and still have the same error. I also might add that I'm using a mac with an updated os. I also hear that it could be an issue of line breaks, but can't find any /n's or /r's in any of the code anyway. I might just be looking in the wrong places, too.

When importing Python modules, you don't need to include the '.py' file extension. So,

from models.py import UUID

...needs to be:

from models import UUID

Hope this helps,

Hello,

I am incredibly new to Django, as-of-today new, so forgive me if I've missed something really obvious.

I've been going through the tutorial and did so mostly-successfully and decided to redo it with my own code.

Everything was going fine until I decided that it would be a good idea to type from models.py import UUID, Students into the shell. With this I received the following error:

/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/django/db/models/base.pyc in __new__(cls, name, bases, attrs)
     90             # For 'django.contrib.sites.models', this would be 'sites'.

     91             model_module = sys.modules[new_class.__module__]
---> 92             kwargs = {"app_label": model_module.__name__.split('.')[-2]}
     93         else:
     94             kwargs = {}

IndexError: list index out of range

I went onto stackoverflow and found some people had similar issues a year ago, and suggested that a person delete the pyc files, which I did. It was also suggested that you make DEBUGGING = False, or True or whatever is opposite. I did this, too, only to find the same error.

I did some other things too, all to no avail... all the same error. I even checked to make sure I was saving edited files, TWICE. Still, same error.

With this, I ask for your help o' wise ones.

Thanks.
