Search and display results using calendar in Django

Hi Everybody,

I need help.

I want to perform search operation using calendars. I shall select two dates i.e. max_date which shall not be more than the current date but can be less and min_date, these two shall be the days range. The result fields are: in_count, out_count, and dwell_time. The output should sum up all the results of all the days which are between the max_date and min_date. How can I do that? Please help. Is there a need to define a model for this? I am completely clueless.  

Expected result is getting the output in the same form as in result_list.html with the result of all the fields of the days starting from min_date till max_date getting displayed and the min_date and max_date should also be shown in the template. Kindly help. 

My model :

  class Result(models.Model):        in_count   = models.PositiveIntegerField()      out_count  = models.PositiveIntegerField()      date_time  = models.DateTimeField()      time       = models.TimeField()        def __str__(self):

return "{},{},{},{}".format(self.in_count, self.out_count, self.date_time, self.time) 

My views.py
class ResultListView(ListView):        def get_queryset(self, *args, **kwargs):          qs = Result.objects.all()          print(self.request.GET)          query = self.request.GET.get("q", None)          if query is not None:              qs = qs.filter(                  Q(in_count__icontains=query) | Q(out_count__icontains=query) | Q(date_time__icontains=query) | Q(time__icontains=query))          return qs        def get_context_data(self, *args, **kwargs):          context = super(ResultListView, self).get_context_data(*args, **kwargs)            return context      class ResultDetailView(DetailView):      queryset = Result.objects.all()

My result_list.html  

<div class="card-header">Result on {{ object.date_time}}</div>    <div class="card-body">      <h3 class="card-title"><a  href="{% url 'result:result' %}"style="color: white; ">Result of Model</a></h3>      <p class="card-text"> In Count {{ object.in_count }}</p>        <p class="card-text">Out Count {{ object.out_count}}</p>
