How to import data in batches with ajax

This time I will show you how to batch import data with ajax. What are the precautions for ajax batch import of data? The following is a practical case, let's take a look.

The example of this article shares with you the implementation method of using ajax to realize the batch import data function in the web page for your reference. The specific content is as follows

url.py code:

url(r'^workimport/$', 'keywork.views.import_keywork', name='import_keywork')

view.py code:

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)

This part of the code refers to the previous article (

Django batch import of non-duplicate data)

Code in the template:

$('#btn_sjdr').click(function(){
   $.post("{% url 'import_keywork' %}",
     {
       csrfmiddlewaretoken:"{{ csrf_token }}",
      file_keywork:$("#file_keywork").val(),
     },
     function(data,status) { 
      $("#test1").html(status+"重复数据"+data['fail']+"条,成功导入数据"+data['success']+"条");   
     }           
   )
  });  
<form>
     {% csrf_token %}
     <label><i class="icon-file"></i> 请选择需要被导入的文件</label>
     <input id="file_keywork" type="file"/>
     <input type="button" id="btn_sjdr" value="导入" class="btn btn-primary btn-sm"/>
    </form>
    <p id="test1"></p>
   </p>

The form uses post+ajax. Note that using the post method to submit a form in Django must meet two conditions:

Add {% csrf_token %} to the form, and add csrfmiddlewaretoken:"{ to the

jquery code { csrf_token }}", that's it!

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the PHP Chinese website!
