I'm new to Django.
Now I'm learning Django, using Writing your first Django
app<https://docs.djangoproject.com/en/dev/intro/tutorial01/> (version
1.5.2) tutorial.
I'm a *Windows 7 * and *Sublime Text 2* user.
Following this tutorial, I created a project called *newweb*
in*C:\DjangoProjects
*.
And then in the *newweb* project I created an app called *polls*.
So, now I have the following directory structure:
newweb/
manage.py
newweb/
__init__.py
settings.py
urls.py
wsgi.py
polls/
__init.py__
admin.py
models.py
tests.py
- In the *models.py* file I have the following code:
from django.db import models
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
- When I build this code in Sublime Text 2 I get this error message:
Traceback (most recent call last):
File "C:\DjangoProjects\newweb\polls\models.py", line 3, in <module>
class Poll(models.Model):
File "C:\python27\lib\site-packages\django\db\models\base.py", line 93,
in __new__
kwargs = {"app_label": model_module.__name__.split('.')[-2]}
IndexError: list index out of range
- What to do?
I have read that to prevent this problem I have to add a *meta* class to
each of my classes (*and it works for me*).
*But *in the Django documentation I read the following:
If a model exists *outside* of the standard locations (models.py or a
models package in an app), the model must define which app it is part of.
And this is *not my case*.
So what's wrong with that? It must work well without *meta* classes.
CONFIGURATION
- I have added the *polls* app to* INSTALLED_APPS* in the *settings.py*file.
- I synced the database (sqlite3), using *manage.py syncdb*
- And what I have on my *PYTHONPATH*:
[' ',
'C:\\python27\\lib\\site-packages\\distribute-0.6.49-py2.7.egg',
'C:\\python27\\lib\\site-packages\\pip-1.4.1-py2.7.egg',
'C:\\DjangoProjects\\newweb',
'C:\\Windows\\system32\\python27.zip',
'C:\\python27\\DLLs',
'C:\\python27\\lib',
'C:\\python27\\lib\\plat-win',
'C:\\python27\\lib\\lib-tk',
'C:\\python27',
'C:\\python27\\lib\\site-packages']
Also, I will say anything you ask.
Thanks.
