I think you would be better off doing this via get_context_data. Manually create your HTML form and use GET to retrieve this data. An example from something I wrote is below. When you submit the form, you can use the get data to pass back via the context data. This example isn't tailored to your request, but it should help other users.

def get_context_data(self, **kwargs):
    context = super(Search, self).get_context_data(**kwargs)
    filter_set = Gauges.objects.all()
    if self.request.GET.get('gauge_id'):
        gauge_id = self.request.GET.get('gauge_id')
        filter_set = filter_set.filter(gauge_id=gauge_id)

    if self.request.GET.get('type'):
        type = self.request.GET.get('type')
        filter_set = filter_set.filter(type=type)

    if self.request.GET.get('location'):
        location = self.request.GET.get('location')
        filter_set = filter_set.filter(location=location)

    if self.request.GET.get('calibrator'):
        calibrator = self.request.GET.get('calibrator')
        filter_set = filter_set.filter(calibrator=calibrator)

    if self.request.GET.get('next_cal_date'):
        next_cal_date = self.request.GET.get('next_cal_date')
        filter_set = filter_set.filter(next_cal_date__lte=next_cal_date)

    context['gauges'] = filter_set
    context['title'] = "Gauges "
    context['types'] = Gauge_Types.objects.all()
    context['locations'] = Locations.objects.all()
    context['calibrators'] = Calibrator.objects.all()
    # And so on for more models
    return context
