While working through the tutorial, I reached the section where you modify the polls/models.py file.
I got a max_length error (running development code (rev 7028)):
>python manage.py sql polls
mysite.polls: __init__() got an unexpected keyword argument 'max_length'
1 error found.
Traceback (most recent call last):

dels.py", line 4, in Poll
question = models.CharField(max_length=200)
TypeError: __init__() got an unexpected keyword argument 'max_length'
After removing 'max_length=' from the code to see what happened, I received the following error:
>python manage.py sql polls
polls.poll: "question": CharFields require a "maxlength" attribute.
polls.choice: "choice": CharFields require a "maxlength" attribute.
2 errors found.
The tutorial still has the underscore in max_length in the sample code.
After removing it, it worked.
Solution:
Make the following change to the sample code (max_length -> maxlength):
from django.db import models
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(maxlength=200)
votes = models.IntegerField()
Thanks,
Mike
