如何将旧记录与新记录进行比较然后导入新记录

Question

我试图使用Biometric Device Integration模块来从生物特征识别设备导入考勤，但是我发现它在每次导入事件后都删除了出勤记录想。所以我删除它删除上座率从我的机器，但在这里，我再次发现，当我导入函数复制人次

我要的是它的旧记录（人次）用新的和进口的只是新的记录进行比较的功能。

@classmethod 
 
    def import_data_classmethod(
 
      cls, biometric_machine, biometric_data_obj, biometric_user_obj,): 
 
     attendances = biometric_machine.getattendance() 
 
     # Sorted elements using user_id and timestamp 
 
     attendances.sort(key=lambda x: (x.user_id, x.timestamp)) 
 
     for attendance in attendances: 
 
      user = biometric_user_obj.search([ 
 
       ['biometric_id', '=', int(attendance.user_id), ], ],) 
 
      if not attendance.action_perform: 
 
       continue 
 
      if not user.employee_id: 
 
       biometric_data_obj.create(
 
        {'biometric_user_id': user.id, 
 
        'datetime': attendance.timestamp, 
 
        'action_perform': attendance.action_perform, },) 
 
       continue 
 

 
       
 
      biometric_data_obj.create_hr_attendace(
 
       user.employee_id.id, attendance.timestamp, 
 
       attendance.action_perform, 
 
       user.biometric_device.id,) 
 
     #biometric_machine.clean_attendance()

     attendances = biometric_machine.getattendance()

      del_atten_ids = biometric_data_obj.search([('biometric_user_id','=',user.id),('datetime','=',str(attendance.timestamp))]) 
 
      if del_atten_ids: 
 
          # hr_attendance.unlink(cr,uid,del_atten_ids) 
 
       print "nothing to do" 
 
      elif not del_atten_ids: 
 

 

 

 

 

 
       if not attendance.action_perform: 
 
        continue 
 
       if not user.employee_id: 
 
        biometric_data_obj.create(
