FWIW, I just started using django-compress
(http://code.google.com/p/django-compress/) which works precisely this
way. It has pluggable compressors, control over the versioning of the
combined files, and so on.

I like the idea of having these "bundles" or "stacks" for media. Just
thinking out loud here, if there were a compression engine in play
that could do concatenation as well as minification you could have a
useful syntax for ordered combinations of scripts similar to how
ModelAdmin's fieldsets work (using a dictionary of nested tuples).
A quick example:
scripts = {
"head": (
"media/js/script_to_be_loaded_first.js",
),
"tail": (
"media/js/script_that_shouldn't_be_concatenated.js", ("media/
js/concatenate_me_1.js", "media/js/concatenate_me_2.js"),
)
}
That would give you the benefit of automated concatenation while
somewhat alleviating the problem Kevin Howerton pointed out about it
best being done by hand.
That's my thought for the moment.

I've been thinking about this ever since I learned that django's admin
was going to be using jQuery, but I admit I didn't really consider it
that important until recently (building sites against 1.2-beta).
I know now is not a fantastic time to be talking about features, but
this is something I'd enjoy working on (personally), and I am just
hoping to get a little feedback regarding the design, and how it might
fit in with everything else going on in django's guts
(philosophically). I also understand that this isn't something for near
versions of django, but rather the distant future.
Here's where the pin dropped:
* The jQuery used by the admin site is conjured using the no conflict
option and is relegated/isolated to it's own namespace (excellent).
* There are many projects/apps out there that also rely on jQuery - they
also "bundle" the framework, but may not be quite so quick to play nice.
In my case, I noticed that when I added a few jQuery-enhanced form
widgets to a form in my admin site, it resulted in 3 instances of the
framework being sourced in the document head. Although, this is
actually ok for the most part in terms of operation (so long as the
scripted events that come with each widget are bound to the dom before
the plugin of origin gets wiped by the next sourcing of jQuery), it's
far from ideal.
There are a myriad of ways to skin this cat, be it a simple
recommendation to adopt the use of django's jQuery and a template tag
to provide access to the appropriate script tag, or something more
structured/engineered/formal ....
My goal would be to provide app developers with scaffolding to add
javascript/css resources to the rendered view in a non-competitive way.
I'm thinking in terms of a template tag that works along the lines of {%
include %}, but for script and link tags, allowing folks to add scripts
with an optional way to influence the position in the "stack". A
similar interface would also be provided for form media, and perhaps
some kind of helper or shortcut for ease the addition of these scripts
from our view functions.
I understand that Django has historically been
anti-javascript-framework-blessing, and I'm wondering if opening this
can of worms would mean having to incorporate some kind of a pluggable
backend system (for working with different frameworks, or multiple
frameworks at a time) - something I've briefly considered, but started
foaming at the mouth as a result.
I've also considered the fact that the reaction here might be, "just
don't - leave it all in the individual's hands".
In closing... don't hit me!

Owen Nelson
