Why not do this: class Polygon(models.Model): sides = models.IntegerField() side_length = models.IntegerField() def perimeter(self): return sides * side_length (Forgive the syntax. I'm a bit rusty.) This doesn't help with irregular polygons, but with your example, it doesn'

It looks like the issue is one of indentation. There's nothing for "self" to refer to if the method isn't part of the class. --And you're probably better off using __unicode__ than __str__ Try: class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateF

That's because the table storing your information doesn't have an "EventDate" field, and it can't be ordered by something that doesn't exist. You'll need to update the table before it will work correctly. On Mon, Mar 31, 2008 at 1:25 AM, Ryan Vanasse <[EMAIL PROTECTED]> wrote: > > I just comment

I'm not sure how this is more transparent. Don't you mean *less* transparent for your user? Instead of a simple number (or more usable user-defined slug), you're giving them a random string, which will be almost impossible to remember and contains no discernibly useful information. If you *really*

It doesn't necessarily hurt to have apps inside the project folder, but it does make it harder to extract and reuse them. If I remember correctly, you don't need much, aside from settings.py, urls.py, and __init__.py. On Fri, Apr 11, 2008 at 1:09 PM, andy baxter <[EMAIL PROTECTED]> wrote: > >

Using a database doesn't by default make your site searchable. It's a more efficient storage system (usually) than having a bunch of static files. SQLite is an easy way to develop, especially if you're running Python 2.5, but I usually move to a PostgreSQL backend for "production" sites, since SQ

There's nothing wrong with parceling out models across different apps. And unless you're planning on distributing each app separately, don't worry about cross-app dependencies. In this case, I'd encourage you to--since you'll probably want to do more than just book-related stuff with your people.
