I have a page that needs to get a few values via the aggregate
function of querysets. There are about 15 of them, and they all look
like this:
SELECT SUM(some_column_name) FROM ...
and they each take a few hundred milliseconds each. That makes the
page take a lot longer to render than I'd like. I
Thanks Karen.
I removed the custom form from admin.py and added a constructor to the
model:
def __init__(self, *args, **kwargs):
super(BannerImage, self).__init__(*args, **kwargs)
self._meta.get_field('url')._choices = get_urls()
It seems to work now.

I have a function called get_urls that returns a list of absolute_urls
for various models in the same project. This function is used for
another model in a way so that when a particular model appears on the
site, I can choose which part of the site this model links to.

Is there a way to disable QuerySet caching? Thanks.

Sorry for the mistake. This should read:

Do a list() on query set and cache the resulting list.

Entire fragments
implement caching on my normal views for authenticated
users? I can't just use the decorator because I have a "Hello,
Username" message on the page.
I tried to look at caching querysets, but this won't work because they
are lazy.
If I use fragment caching, would that save
