Having a tough time getting started with Django

[Peter L. Berghold]

OK: Trying to get a handle on getting started with Django and like I
always do when learning a new environment I've dived in head first.

Here is an error message I'm getting.

peter@slcjwebapp0:~/agilitystewards$ python manage.py syncdb
Error: Couldn't install apps, because there were errors in one or more
models:
agilitystewards: __init__() got an unexpected keyword argument
'max_length'

Now, my models file almost looks like the example that I saw on the
Django web site and here it is:

peter@slcjwebapp0:~/agilitystewards$ cat models.py
from django.db import models

class Person(models.Model):
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)

class Person2(models.Model):
given_name=models.CharField(max_length=40)
surname = models.CharField(max_length=40)

class Account (models.Model):
person = models.ForeignKey(Person)
login_id = models.CharField(max_length=15)
password = models.CharField(max_length=30)
lastLogin = models.DateTimeField()

class Dog (models.Model):
person = models.ForeignKey(Person)
callname = models.CharField(max_length=20)
jump_height = models.IntegerField()

class Venue (models.Model):
name = models.CharField(max_length=30)
abbr = models.CharField(max_length=10)

class CompeteLevel (models.Model):
venue = models.ForeignKey(Venue)
name = models.CharField(max_length=50)
abbr = models.CharField(max_length=8)

class EventClassType (models.Model):
venue = models.ForeignKey(Venue)
name = models.CharField(max_length=50)
abbr = models.CharField(max_length=8)

class Club (models.Model):
name = models.CharField(max_length=30)
abbr = modesl.CharField(max_length=10)

class Trial (models.Model):
venue = models.ForeignKey(Venue)
club = models.ForeignKey(Club)
name = models.CharField(max_length=50)

RUNNING_ORDER_CHOICES = (
('B','Big to Small'),
('S','Small to Big')
);

class TrialDate(models.Model):
trial = models.ForeignKey(Trial)
day_date = Models.DateField
running_order =
Models.CharField(max_length=1,choices=RUNNING_ORDER_CHOICES)
nrings = Models.IntegerField()

class Ring(models.Model):
trialDate = models.ForeignKey(TrialDate)
ringHandle = Models.CharField(max_length=30)

Nothing really fancy there.

Here is the settings.py file.

OK... so what am I missing here? My assumption is that I'm the one
messed up here, not Django, so where am I going wrong?

What version of Django have you installed? It appears to be earlier than 1.2 at least, because the method of specifying database connections in settings.py changed in that release. It's possible that you have installed a *very* old - ie pre-1.0 - version, in which the max_length parameter was called maxlength (without the hyphen). If so, please uninstall it and install the up-to-date version.

Check the capitalization of the word "models" in some of your model
definitions.

You were right on the money. I just checked the Debian site and the
Django loaded via apt-get is version 1.02. (not a typo... there's a zero
there...)

I'll see about installing the "latest and greatest" version. Thanks for
the nudge.
