python - Dynamic querys in Django using *args and **kwargs -


i'm trying create search form user can choose few options filter search. i'm getting error:

sortedbyscore() argument after * must sequence, not q

views.py:

def results(request):     if request.method != "get":         return httpresponse("request method needs get")     else:         bound_search_form = searchform(request.get)         query = request.get['query']         subject = request.get['subject']         grade = request.get['grade']         order_by = request.get['order_by']         kwargs = {}         args = ()         if query:             query_word_list = query.split()             args = reduce(operator.or_, ((q(title__contains=x) | q(content__contains=x)) x in query_word_list))         if subject != 'all':             kwargs["subject"] = subject          summaries_list = summary.objects.sortedbyscore(*args, **kwargs)         length = len(summaries_list)          # pagination         paginator = paginator(summaries_list, 4)          # page number request         page_num = request.get.get('page', 1)          # summaries paginator according page number         try:             summaries = paginator.page(page_num)         except(emptypage, invalidpage):             summaries = paginator.page(paginator.num_pages)          context_dict = {             'sumamount': length,             'summaries': summaries,             'search_form': bound_search_form,         }          return render(request, 'results.html', context_dict) 

code custom manager sortedbyscore:

class summarymanager(models.manager):     def sortedbyscore(self, *args, **kwargs):         summaries = self.get_queryset().filter(*args, **kwargs)         return sorted(summaries, key=lambda summary: summary.get_score(),reverse=true) 

args = reduce(operator.or_, ((q(title__contains=x) | q(content__contains=x)) x in query_word_list)) 

reduce reduces iterable down single object, after line args not iterable. reduces args down single q object ors of items in query_word_list together. if want pass using * syntax, you'll need wrap in iterable, i.e. args = (args,).
