Unable to access project API in Django in tutorial

I was going through this tutorial in order to learn how Django works:

https://docs.djangoproject.com/en/dev/intro/tutorial01/

Now, when I get to the part where you execute python manage.py shell, I enter the shell and try to run the different commands, I get this:

>>> Poll.objects.all()

Traceback (most recent call last):

  File "\", line 1, in \

NameErro开发者_StackOverflow社区r: name 'Poll' is not defined

What am I doing wrong? I re-ran the previous steps as best I could.

You should have imported Poll with from polls.models import Poll

Kamyar is almost right, if you received this error you probably missed the first line of the code, which is

>>> from polls.models import Poll, Choice # Import the model classes we just wrote.

so do that and you should be fine.
