Hi,
I'm am trying to follow along with the tutorial, but keep getting this
error when I migrate the models. Here is my models.py file for the polls
app:
from django.db import models
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTim
Ah, worked perfectly. Thanks so much!

I keep on getting "FieldDoesNotExist" errors. They are saying that a
field, in this case "p", doesn't exist. I don't know what it is
talking about because I am not trying to call "p".
Any ideas?

Hi Jacob,
thanks, it's good to know that I'm not going to find the bug in my
code.
While trying different things, I too found out that adding the
"ordering"-option made the listview work again. The first thing I tried
was adding ordering = ['theparent']:
class FirstChild(meta.Model):
Programme\Python24\lib\site-packages\django\views\admin\main.py",
line 132, in change_list
if isinstance(lookup_opts.get_field(order_field).rel,
meta.ManyToOne):
File
"C:\Programme\Python24\lib\site-packages\django\core\meta
\__init__.py",
line 252, in get_field
raise Fiel
oOne):
File
"C:\Programme\Python24\lib\site-packages\django\core\meta\__init__.py",
line 252, in get_field
raise FieldDoesNotExist, "name=%s" % name
FieldDoesNotExist: name=_order
Any ideas how I can get that to work?
