Hello to everyone,
I'm quite new so please go easy on me.
I already searched on the mailing list but couldn't find a good answer for
my problem.
I am writing a project for a website where i retrieve events from a
database, together with them I need, on the same page, to show a list of
banners, taken from an other model other than the one regarding the events.
Here is the code:
-------------------------------------------------
class CampagnaPubblicitaria(models.Model):
...
sponsor= models.ForeignKey(Sponsor)
def in_campagna(self):
#determina il periodo della campagna pubblicitaria
oggi= datetime.toordinal(TODAY)
data_inizio_campagna_ord=
datetime.toordinal(self.data_inizio_campagna)
if data_inizio_campagna_ord<= oggi <=
(data_inizio_campagna_ord+ self.durata_campagna):
return True
else:
return False
...
class Sponsor(models.Model):
banner= models.ForeignKey(Banner)
...
-------------------------------------------------
Now, I am using django own generic date based views and i am trying to
pass as an extra_context value this:
banner_list=
Banner.objects.filter(sponsor__campagnapubblicitaria__in_campagna=
True).order_by('?')[:6]
evento_index_info_dict= {
'queryset': Evento.objects.all(),
'date_field': 'data_di_inserimento',
'extra_context': {'banner_list': banner_list}
}
But when i try to have a look at the page, i get this error:
---
TypeError at /
Cannot resolve keyword 'in_campagna' into field
---
Is that because the QuerySet doesn't actually evaluate the value of
in_campagna for every record of the database? Is there any other way to do
the same job, other than writing a huge filter? ^^'
And, am I wrong i pass the extra_context in a "urls" context rather than a
"view" context? Is there any other way to write extra_context for the
template other than write it directly on the urls.py code?
Thanks in advance if anyone will have the patience to understand what i
wrote and the patience to reply me.
Regards,
David
