Django框架利用ajax实现批量导入数据功能

from keywork.models import DevData
from django.http import JsonResponse #django ajax部分

def import_keywork(request):
 file_sjdr = request.POST['file_keywork']
 f = open(file_sjdr)
 WorkList = []
 next(f) #将文件标记移到下一行
 x = y = 0
 for line in f:
  parts = line.replace('"','') #将字典中的"替换空
  parts = parts.split(',') #按;对字符串进行切片
  if DevData.objects.filter(serv_id = parts[0],user_flag=parts[15]).exists():
   x = x + 1
  else:
   y = y + 1
   WorkList.append(DevData(serv_id=parts[0], serv_state_name=parts[1], acc_nbr=parts[2], user_name=parts[3], acct_code=parts[4], product_id=parts[5],
       mkt_chnl_name=parts[6], mkt_chnl_id=parts[7],mkt_region_name=parts[8], mkt_region_id=parts[9],mkt_grid_name=parts[10],
       sale_man=parts[11],sale_outlets_cd1_name=parts[12], completed_time=parts[13],remove_data=parts[14], user_flag=parts[15],
       pro_flag=parts[16], service_offer_id=parts[17],service_offer_name=parts[18], finish_time=parts[19],staff_name=parts[20],
       staff_code=parts[21],org_name=parts[22],prod_offer_name=parts[23],day_id=parts[24],
       ))
 f.close() 
 DevData.objects.bulk_create(WorkList)
 num = {'success':str(y) ,'fail':str(x) , 'sum':str(x+y)}
 return JsonResponse(num)
