Warning about missing setup_test_environment() call in tutorial 5

[cfperea@…]

Hi, I've been following the official Django tutorial and came across a possible error in the documentation using version 1.6.
In the section titled The Django test client (​https://docs.djangoproject.com/en/1.6/intro/tutorial05/#the-django-test-client) in part 5 there is this section of code:

>>> # get a response from '/'
>>> response = client.get('/')
>>> # we should expect a 404 from that address
>>> response.status_code
404
>>> # on the other hand we should expect to find something at '/polls/'
>>> # we'll use 'reverse()' rather than a hardcoded URL
>>> from django.core.urlresolvers import reverse
>>> response = client.get(reverse('polls:index'))
>>> response.status_code
200
>>> response.content
'\n\n\n    <p>No polls are available.</p>\n\n'
>>> # note - you might get unexpected results if your ``TIME_ZONE``
>>> # in ``settings.py`` is not correct. If you need to change it,
>>> # you will also need to restart your shell session
>>> from polls.models import Poll
>>> from django.utils import timezone
>>> # create a Poll and save it
>>> p = Poll(question="Who is your favorite Beatle?", pub_date=timezone.now())
>>> p.save()
>>> # check the response once again
>>> response = client.get('/polls/')
>>> response.content
'\n\n\n    <ul>\n    \n        <li><a href="/polls/1/">Who is your favorite Beatle?</a></li>\n    \n    </ul>\n\n'
>>> response.context['latest_poll_list']
[<Poll: Who is your favorite Beatle?>]

However, when I wrote this test in the console the following error occurred:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: 'NoneType' object is not subscriptable

I changed the line

response.context['latest_poll_list']

to

response.context_data['latest_poll_list']

and it worked as intended.

I'm using Python 2.7 with Django 1.6 in a Windows 7 machine.

Ah, I figured this out. If you omit setup_test_environment() mentioned earlier, you'll run into this. We should add a warning as it's been reported several times.
