Hi Carlos,
You probably want to create a new widget and override its label_from_instance
method.
class BModelMultipleChoiceField(forms.ModelMultipleChoiceField):
def label_from_instance(self, obj):
return "%s (%s)" % (obj, obj.count_a)
And then you'll want to change your

Hmm, I'd rethink my datamodel. Everything is far easier to hand
You should use staticfiles to include your css, js and image in your page.
You first need to load the module in your template, then you can use
the static tag
{% load staticfiles %}
While you are in dev, static will look into each of your app's static
directory for the path you passed as argumen
Hi, do you mean to store some kind of duration? There's DurationField for that.
And you could store datetime.timedelta there. To get timedelta between two
datetime.datetime objects, you could subtract ine from another:
from django.utils import timezone as tz
now = tz.now()
day_ago = tz.now() -
Here is an exemple, slightly simplified from one of my project
Assuming a "generic" app, generic/templates/base.html would be
something like that
{% load staticfiles %}
{% block title %}myfb{% endblock %}
{% block content %}{% endblock %}
with style.css in generic/static/css/style.css and gene

list =
DateTimeDuration.objects.all().filter(date=now).order_by('resource','start')
max_hours = 8
this produces
Resource – start – duration – user-name
Item - 9 - 4 - T Test
Item- 10 - 4 - Alpha Bravo
Item - 14 - 2 - Herod First

I second the need to put js and css files under a static directory. When
going to production, you'll need to look at the management command about
static files.
Also, don't put html files outside templates directory. And unless you have
a good reason not to, put the html files in a subdirectory of
