IDLE (Python GUI)

[Mikey3D]

Windows 7:

My project is in: C:\Python26\Lib\site-packages\mysite

I'm working on this section: Playing with the API
http://docs.djangoproject.com/en/dev/intro/tutorial01/#playing-with-the-api

When I do (Windows+R >cmd >OK) to do python shell (python manage.py
shell) it works. But I have try other tool that come with Python26 is
IDLE (Python GUI) and I get an error:

I don't understand how and where to settings DJANGO_SETTINGS_MODULE?

I think what you need is the following before you import anything from Django: (or any module that imports from Django):

import os
os.environ['DJANGO_SETTINGS_MODULE'] = "settings"

(The absolute or relative path to your settings file.)

The second task I put the code what you suggest in mysite\settings.py:

I try this but get an error:

==============================================================================================

The third task it does works:

>>> import os
>>> os.environ['DJANGO_SETTINGS_MODULE'] = "mysite.settings"

>>> import mysite
>>> from mysite.polls.models import Poll, Choice

>>> Poll.objects.all()
[]
>>> import datetime
>>> p = Poll(question="What's up?", pub_date=datetime.datetime.now())
>>> p.save()
>>> p.id
1
>>> p.question
"What's up?"
>>>

I have trying 3 difference tasks but the last one it works.

Thanks, Nick
