class view with filter on form input

[Bob Bobsled]

Hi,

I have form on a search page  called SearchForm where the user selects items to search.

The rest part creates a URI which appears as below from the selected items to search.

http://archive/ephemera/searchresult/?choose_collection=Macmillan&user_input=GuitarBuilder&choose_item=title

I'm trying to write a classview in views.py to get the URI parameters, then

fashion a query to place those in an object_list for viewing in a search results template.

views.py

class SearchResultsView(django.views.generic.ListView):

template_name = 'ephemera/searchresults.html'

model = Item  #my model class

def get_queryset(self, **kwargs):

form = SearchForm()

choose_collection = self.request.GET.get('choose_collection')

user_input = self.request.GET.get('user_input')

choose_item = self.request.GET.get('choose_item')

                object_list = self.model.objects.filter(collection__icontains = choose_collection).filter(choose_item__icontains = user_input)   #XXX

return object_list

I can't seem to figure out how to pass the choose_item get variable to the filter.  Django complains cannot resolve keyword 'choose_item' into field.  The correct field is 'title' but I won't know that until the user selects one of the choices from the form pull down menu.

The following query works fine directly on sqlite, but I can't seem to figure out how to do it in the class view.

select * from ephemera_item where collection = 'MACMILLAN' AND title = 'Guitar Builder';

Could be my basic approach is bad too, because I'm only just starting out with this.

Thank you for any advice.

Regards,

Bob
