I'm writing a custom Manager to only return objects which fall within
dates set for Active From and Active To fields. It currently looks
like this:

def get_query_set(self):
objects = super(ActiveManager, self).get_query_set()
objects =
Thanks Mike - that did the trick. I thought there would be a simple

Just a quick query about the SelectDateWidget:
The widget accepts an optional 'years' parameter for displaying a
range of years, like this:
SelectDateWidget(years = range(1900, 2006))
But is there an easy way I can make the years display in reverse -
i.e. descending rather than ascending?
Hi,
I have this:
class SomeModel(models.Model):
some_choice = models.CharField(maxlength=255, choices=CHOICES_DICT)
And I'm generating a form for HTML display using this:
SomeForm = newforms.models.form_for_model(SomeModel)
form = SomeForm()
But my some_choices field just shows up

Hi,
Can anyone provide any pointers on how I use MultiValueField? Can I
use it straight out of the box, or do I have to subclass to create a
new field and a new MultiValueWidget?
I thought that this code would just work:
postcode = forms.MultiValueField(fields=(forms.CharField(max_length=4),

Apologies if this has been asked on the list before, but a search

I want to have a series of pages, with certain areas of content which

I've got a Django app with a whole stack of data which I want to be
able to update on a semi-regular basis. It's currently in Excel
format, which is then easily converted to CSV and imported into a

it.
It all works
That's excellent - strange I came across the problem right at the same

Thanks for the feedback guys - good to know that I'm not alone in
seeing this behaviour.
It seems odd that this doesn't seem to have popped up as a common
issue, if it is indeed something related to site-wide caching - it's
definitely a bit of a show-stopper when it comes to having a client
Hi,
Perhaps I'm missing something simple, but ever since I enabled caching
middleware in my apps, I've noticed that it's causing lots of strange

not showing up, messages taking a while to filter through.

Thanks for the update Patrick. I've got this part working, but having

As far as I know, there's no way to restrict the number of instances
of a particular model. You could hack the admin templates to hide
"Add" buttons if an instance of a particular model already exists. Or
override the save method in the model so that it doesn't save if an
instance already

There's one very good reason why Django (and any other framework / CMS
worth it's salt) deliberately avoids serving static files, and that
reason is "performance".
Your content serving mechanism should be about retrieving and
manipulating content data, and performance can be haevily impacted if
