Playing with API- DjangoProject Part 1

[Auj Snow]

When I run the shell, I keep getting errors. Also, I have created the question three times now so when I type q.id , I get a return value of 3. How can I delete them. Also when I ask the question text (q.question_text) I get "<Question: Question object>" instead of the "Whats up". 

Any help would be greatly appreciated. 

The error when I run the shell:

q$ python manage.py shell

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/models/base.py:309: RuntimeWarning: Model 'polls.question' was already registered. Reloading models is not advised as it can lead to inconsistencies, most notably with related models.

  new_class._meta.apps.register_model(new_class._meta.app_label, new_class)

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/models/base.py:309: RuntimeWarning: Model 'polls.choice' was already registered. Reloading models is not advised as it can lead to inconsistencies, most notably with related models.

This worked for me in ubuntu:

python manage.py shell

Python 3.4.0 (default, Apr 11 2014, 13:05:11)

[GCC 4.8.2] on linux

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)

>>> from polls.models import Question, Choice

>>> from django.utils import timezone

>>> q = Question(question_text="What's up?", pub_date=timezone.now())

>>> q.save()

>>> q.id

1

>>> q.question_text

"What's up?"

I just did the above and I got a message

from this page url:https://docs.djangoproject.com/en/1.8/intro/tutorial01/

I hope this helps, try it again

Easy enough.

q.delete()

You may have to perform a query to gather up the other questions that
you've already created and perform delete operations on each of those.

That is odd. I'd be interested to see the series of commands that you
are running to get this result. Can you paste everything that you are
typing into the shell and all of the responses? It's almost as though
you've done something like p.question_text = p before printing out p.

While I've never seen this error before, it would seem that something
is amiss in your models.py and/or possibly your admin.py. I've seen a
few google posts saying that this error was received because they were
importing models in both models.py and in admin.py.

Please post both files, along with your settings.py, which may shed
more light on the issue.

Thank you for your help James. I have deleted the the folder the contained the framework and will be starting from scratch.

I completed 'learn python the hard way' along with a few more beginner level courses for python. I'm sure you read or get this question daily, but what would you recommend is a good place to start for Django. I feel I need some more explanations and basic level knowledge than what's on the djangoproject. I want to create my own landing page that has sign in and log in features for a set of questions to be asked. Ultimately, I want to get familiar with Django. I started coding about 3 months ago and I have absorbed a lot considering my background prior experience. 

Any advice would be helpful. Thanks for all the support!

Best advice is to read the overview page, and then follow the tutorial link. After you've completed the tutorial, you should have a good understanding of where to go and what you can do with Django:
