Django:按两个整数的范围筛选对象

如何在汽车对象中搜索价格在此范围内的对象(price-from-price-to),是否应修改模型?

# model
class Car(models.Model):
    id = models.CharField(max_length=255)
    number = models.CharField(max_length=255)
    price = models.IntegerField()

# view
def search(request):
        if 'search_filter' in request.GET:
            search_params = request.GET.dict()
            search_params.pop("search_filter")
            price_from = search_params['price_from']
            price_to = search_params['price_to']
            q_list = [Q(("{}__icontains".format(param), search_params[param])) for param in search_params 
            if search_params[param] is not None]  

            my_query = Car.objects.filter(reduce(operator.and_, q_list))
            cars = [{
                'id': x.id,
                'driven': x.driven,
                'price': x.price,
            } for x in my_query
            ]
            return JsonResponse({'data': cars})
        context = {'cars': Car.objects.all().order_by('price')}
        return render(request, 'cars/car_index.html', context)
