# Create three choices.>>> p.choice_set.create(choice='Not much', votes=0)<Choice: Not much
>>> p.choice_set.create(choice='The sky', votes=0)<Choice: The sky
>>>> c = p.choice_set.create(choice='Just hacking again', votes=0)
# Choice objects have API access to their related Poll objects.
>>> c.poll<Poll: What's up?># And vice versa: Poll objects get access to Choice objects.
>>> p.choice_set.all()[<Choice: Not much>, <Choice: The sky>, <Choice: Just hacking again>]
>>> p.choice_set.count()
