Question

你能帮我吗？如何在应用程序中显示进度栏？我从数据库获取值并创建所有值组合的列表，然后将文件名保存到数据库并将xml文件保存到磁盘。此操作需要很长时间。我想显示进度条，已经创建了多少文件。进度栏必须保持最新。

def save_auto_xml_tests(request, pk):
serial_port_speed = list(SerialPortSpeed.objects.values_list('value', flat=True))
serial_port_data_bits = list(SerialPortDataBits.objects.values_list('value', flat=True))
serial_port_parity = list(SerialPortParity.objects.values_list('value', flat=True))
serial_port_stop_bits = list(SerialPortStopBits.objects.values_list('value', flat=True))
serial_port_handshake = list(SerialPortHandshake.objects.values_list('value', flat=True))
created = list(itertools.product(serial_port_speed, serial_port_data_bits, serial_port_parity, serial_port_stop_bits, serial_port_handshake))

for item in created
    seeker = Seeker.objects.get(name=modelseeker)
    xml_file_name = time.strftime("%Y%m%d-%H%M%S") + '.xml'
    record = XmlSeeker(xml_file=xml_file_name)
    record.save()

xml_body = "..."
    xml_seeker_test = 'XmlGenerated\\{}\\{}'.format(pk, xml_file_name)
    pathlib.Path('./media/XmlGenerated/{}/'.format(pk)).mkdir(parents=True, exist_ok=True)
    f = open(os.path.join(settings.MEDIA_ROOT, xml_seeker_test), 'w')
    xml_save = ET.ElementTree(ET.fromstring(xml_body))
    xml_save.write(os.path.join(settings.MEDIA_ROOT, xml_seeker_test), encoding="UTF-8", xml_declaration=True)
    f.close()

return redirect('details', pk=pk)

Django ProgressBar用于读取文件
