Hey All,
I've had this problem for a while and still can't figure it out. I
have django setup and working on my windows machine. I can run
manage.py syncdb and other commands, but for some reason the dbshell
command doesn't work. It just gives this error:
> manage.py dbshell
> ERROR 1045 (2800
Alright, after some more searching I figured out my answer. First
off, the test statements I posted were wrong. The first argument
passed to execlp is the executable name, so:

Should be

Currently, the @login_required() decorator does not preserve any #hash
part of the URL. So if I go to /page#section1 without being logged

The first problem is that the django server only receives the '/page'
part of the URL. The browser itself holds onto the '#hash' part and
doesn't transmit that to the django server at all, so the

Yeah, I ended up doing this on the /login page. Basically:

Giancarlo,
I've run into this trouble myself. The problem here is the widget
itself. It does exactly what you described:
-Shows all possible values for the ManyToMany field.
-Highlights the "active" or "selected" values. These correspond to
items in that list/array/queryset.

Tom,
Thanks for the link, I read through that and it makes sense.
So if both conditions are in the same filter, they are both applied
simultaneously. Since I wanted two separate conditions, I needed two
separate filter() statements.

What's your motive? Are you worried about performance?
If performance is not an issue, you can just do this:
for project in Project.objects.all():
print project.user.first_name + ' ' + project.user.last_namea
This might speed things up:
projects = Project.objects.all().select_r
If it were my project, I'd probably add this kind of custom field to
your mapping:
mapping = {

I want to run a script outside of the django server for maintenance

that I can't seem to get the model object to reload it's data from the

I always do something like this:
abs_activate_url =
request.build_absolute_uri(reverse('account_activate', args=user.id))
That's an absolute URL, so it's like "http://domain.com/account/
activate/2" instead of the normal reverse() or {% url %} which gives a
relative URL like "/account/activat
As a followup, I had to do something similar and ended up using this:

base_url = request.build_absolute_uri('/')[:-1]
And in the template I can do this:

I discovered the recent changes to the "is_valid()" model form method
in 1.2, and I'd love to hear thoughts on the rationale behind this
change.
I have this kind of code:

While that didn't solve my original question, it did solve another

they depended on pre-existing data (which did not exist in the blank

How do I record the time each test takes? If this is not (easily)
