If you have no data that is important, I'd just delete the database and
start fresh. If you're using sqlite you can simply `rm db.sqlite3` and then
run python manage.py migrate again.

Kinda worked. I deleted my Poll objects and created a new one. But then, a
few more lines into the tutorial, there are these commands one after
another:
p = Poll.objects.get(pk=1)
p.choice_set.all()
I get: *OperationalError: no such column: polls_choice.choice_text*
It should be simply:
[]
What version of python are you using (2 or 3)?
Poll.objects.all().delete() will delete all of your Poll objects, if you
want. Or it may be simpler to just rm db.sqlite3 and run manage.py
migrate/syncdb again.

But when I enter:
p = Poll(id=1, question="What's new?", pub_date=timezone.now())
p.save()
and then enter:
Poll.objects.filter(question__startswith='What')
it should return:
[]
but it returns:
[, , ]
..and so other commands form the tutorial also return things completely
different from wh
p.id == 3 is just fine. It's auto-incrementing, and even if you delete
items, an object will never get p.id == 1 again.
If you really want a Poll with id=1, either clear out your database, or
create it manually like so:
p = Poll(id=1, question="What's new?", pub_date=timezone.now())
p.save()

thanks, that helped
I also got confused and created too many objects, so now instead of p.id
"1" cdm returns "3". How do I delete objects from p?
>>> from django.utils import timezone>>> p = Poll(question="What's new?",
>>> pub_date=timezone.now())
# Save the object into the database. You ha

Hi guys.
I'm just going through the official tutorial for Django: "Writing your first
Django app, part 1"
At the bottom of the page it says:
# Make sure our custom method worked.
>>> p = Poll.objects.get(pk=1)
>>> p.was_published_recently()
True
So far everything went well but now cmd retur
