Re: Passing a parameter into a queryset for a generic view
I was looking for some convenient method like this to use with the
object_list generic view. But writing my own wrapper view only took 2
secs.
def speaker_list(request, session_month):
if not session_month in settings.SESSIONS:
return HttpResponseNotFound()
speakers = models.SpeakerInfo.objects.filter
(session__contains=session_month)
speaker_info = {'queryset':speakers,
'template_name': 'speaker_list.html',
'template_object_name':'speaker',
'extra_context':{'session_month': session_month,},
}
return object_list(request, **speaker_info)
The good thing about this is you can also validate the path variable
first. Also don't forget to pass the path variable into the template
through the extra_context dictionary if you need it.

Re: Passing a parameter into a queryset for a generic view
There may be an easier way, but I'd write a view, even if
I then called the generic view from there.
As you've probably figured out, your definition of the queryset
occurs once at import, when object_id isn't even defined, let
alone coming from each request in turn.

Passing a parameter into a queryset for a generic view
I want to display all the services for a particular business using the
generic view "object_detail". What I would like to do is pass the
value of an id from the url to the queryset (into object_id) in
urls.py - or a better way to do this using the "object_detail" generic
view.
models.py:
class BusinessService(models.Model):
business = models.ForeignKey(Business)
service = models.ForeignKey(Service)
urls.py:
businessservice_list = {
'queryset' : BusinessService.objects.filter(
business=object_id),
}
...skip some detail...
(r'^showservice/(?P\d+)/$', list_detail.object_detail,
businessservice_list),
businessservice_detail.html:
{% extends "portal/base.html" %}
{% block pagename %}Business Services{% endblock pagename %}
{% block content %}
Business Services
{{ businessservice.business }}
{% for business in object_list %}
{{ businessservice.service }}
{% endfor %}
{% endblock content%}
