The catch is, if you're going in via the "wizard", I want the nav path to be something like "set name" -> "set death ray target" -> "set ...
So I have a Django app that processes test results, and I'm trying to find the median score for a certain assessment. I would think that this would work: e = Exam.objects.all() total = e.count() median = int(round(total / 2)) median_exam = Exam.objects.filter(assessment=assessment.id).order_by('score')[median:1] median_score = median_ex...

I just started playing with Django today and so far am finding it rather difficult to do simple things. What I'm struggling with right now is filtering a list of status types. The StatusTypes model is: class StatusTypes(models.Model): status = models.CharField(max_length=50) type = models.IntegerField() def __unicode__(self)...
Hi. Previously I've been using some older version of django-registration which seems to be deprecated now. Because my server does not allow me to install python plugins I need to use 'registration' as separate django application.

Now, this is brilliant for quick stuff but what I'm trying to do is a little bit more complicated. Consider a DateField - my current form has fields for day, month and year and c...

Sometimes I need to UNREGISTER some ModelAdmins from the admin site, because I don't want them to be there as they are, eg. if I'm using the Sites framework, and I dont want it to appear in the admin. It's no big deal to e.g. call admin.site.unregister(Site) to do so. In most cases I put it in admin.py of some related app that I have mad...

You can see the wip here: http://www.totanus.net/weight/ At this time I'm printing dates in the X-axis usi...
Hi folks, I'm using popen in order to send a few commands within a Django app. Problem is that I'm getting [Error 5] Access Denied, apparently I have no access to cmd.exe, which popen seems to use.
