如何在python（django）中存储计数值？

Question

我正在尝试实现上传限制功能。 我发现除了 count 值之外，一切都按预期工作。

请找到下面的views.py代码。

def CTA_upload(request):
    i = 1
    count = [0,]
    print('Counter value at starting::::::::: :', len(count))
    allcts = CTS.objects.all()
    try:
        if len(count) <= 14:
            if request.method == 'POST':
                movie_resource = CTAResource()
                print('movie_resource', movie_resource)
                dataset = Dataset()
                new_movie = request.FILES['file']
                if not new_movie.name.endswith('xls'):
                    messages.info(request, 'Sorry Wrong File Format.Please Upload valid format')
                    return render(request, 'app/uploadctsa.html')
                messages.info(request, 'stage1 fired:Processing  file type is Okay :)...')
                imported_data = dataset.load(new_movie.read(), format='xls')
                print('abcdefghijk:', type(imported_data))
                messages.info(request, 'Stage2 fired:*** Now checking data inside imported data :)')
                for data in imported_data:
                    value = CTA(
                        data[0], data[1], data[2], data[3], data[4], data[5], data[6], data[7], data[8],
                    )
                    print('Value 1 ::::', value)
                    print('Final Count After entering < = 15:', len(count))
                    messages.info(request, 'Stage3 fired:*** Now entering to check count <= :)')
                    i = i + 1
                    count.append(i)
                    print('Count After Appending Value:',count)
                    value.save()
        else:
            print('Final ***else Count when > = is equal to 15:', len(count))
            messages.info(request, 'Sorry you are uploading more than 15 records so records')
            print('Final count jo hai variable me store:', count)
            messages.info(request,
                          'Sleeping For 10 sec and then it will clear count value. so you can upload extra data after 10 sec..')
            time.sleep(10)
            count.clear()
            print('Counter value after Clearing::::::::: :', len(count))
            messages.info(request,
                          'Sorry You have uploaded more data than specified limit./Same Email ID has been observed more than once.Except that other records has been added../nPlease Make sure Email field should be unique.')
            
    except:
        messages.info(request,'Sorry You have uploaded more data than specified limit./Same Email ID has been observed more than once.Except that other records has been added../nPlease Make sure Email field should be unique.')
        print("Problem hai kuch to")

    return render(request,'app/uploadctsa.html')

问题：这里我正在检查计数，所以如果超过 14 条记录，它将不会保存在数据库中。 我想存储计数值，这样如果在 600 秒内如果有人再次上传任何记录，它将检查计数值然后处理（因为在 600 秒后我正在清除计数值）但是这里计数值没有得到保存对于 600 秒内的每次新上传，也是从头开始。

存储计数值的任何方式，以便如果有人上传任何记录，它将检查计数变量中最后存储的值是什么，然后进行处理。

下面是我得到的终端输出：

Answer 1

    from django.utils import timezone 

    current_date = timezone.now().date()
    created_count = CTA.objects.filter(created_at__date=current_date).count()

根据需要更新过滤器！
