Aggregates in Django templates
In a Django application, I want to display a multi-level (but fixed-depth) tree of model objects in table form. The HTML would look something like this: <tr><td rowspan="2">group 1</td><td>item 1.1</td></tr> <tr><td>item 1.2</td></tr> <tr><td rowspan="3">group 2</td><td>item 2.1</td></tr> <tr><td>item 2.2</td></tr> <tr><td>item 2.3</td>...
Django autoreload for development on every request?
Can a Django app be reloaded on every request ? This is very useful for development. Ruby on Rails does just this. runserver reloads, but it reloads slow, and still sometime one has to stop and start it again for some changes to show up. (For example changes in admin.) mod_wsgi can autoreload on Linux by touching *.wsgi files. On Wi...

Django Templating: how to access properties of the first item in a list
Pretty simple. I have a Python list that I am passing to a Django template. I can specifically access the first item in this list using {{ thelist|first }} However, I also want to access a property of that item... ideally you'd think it would look like this: {{ thelist|first.propertyName }} But alas, it does not. Is there any temp...

Case-insensitive comparison of sets in Python
I have two sets (although I can do lists, or whatever): a = frozenset(('Today','I','am','fine')) b = frozenset(('hello','how','are','you','today')) I want to get: frozenset(['Today']) or at least: frozenset(['today']) The second option is doable if I lowercase everything I presume, but I'm looking for a more elegant way. Is it ...
Django startup importing causes reverse to happen
This might be an isolated problem, but figured I'd ask in case someone has thoughts on a graceful approach to address it.

Django instance start under Google App Engine
After thinking quite a while about how to make a fast and scalable web application, I am almost decided to go for a combination of Google App Engine, Python+Django, and app-engine-patch. But I came across a comment in the app-engine-patch FAQ that made me think that perhaps the combination is not quite as mature as I thought: it may take...

Template-level model methods in Django to respect both DRY and MTV (MVC)?
As an example, let's say there's a Tshirt model on a shopping site, and it will have "summary" markup with a thumbnail, name and price: <div> <a href="detailspage">Awesome TShirt!</a> <img src="thumbnail.jpg" /> <span class="price">$55.99</span> </div> Since this will be on many different pages, I don't want to have to typ...
