I need to create a tree of unordered lists based on these fields. Ultimately, it would look something like this: A1 B1 C1 D1 D2 C2 D3 D4 B2 C2 D5 D6 C3 D7 D8 A2 B2 C1...

In the case of multiple projects on the same site(domain) should I use a unique DATABASE_USER per each project database? In the case of mu...
I've recently become a little frustrated with Django as a whole. It seems like I can't get full control over anything. I love Python to death, but I want to be able (and free) to do something as simple as adding a css class to an auto-generated form. One MVC framework that I have really been enjoying working with is Grails (groovy). It...

The thread pages look a little different for each user, so you can't cache the rendered page as whole and caching only some parts of the rendered pa...
