django防止表單數據重復提交

思路：
        GET訪問時，服務器返回頁面，同時生成認證token,保存入session

       POST訪問時，校驗客戶端的token與session中保存的token是否一致

具體代碼：

import uuid

from django.http import HttpResponse
from django.shortcuts import render,render_to_response

from DataAccess.Supplier import supplier_DAC
from common import utils
from common.Supplier import urlconfig
from Supplier.supperForm import SupplierForm
# Create your views here.
def index(request):
 supplier_table_data=supplier_DAC.getAllSupplierInfo()
 page_id=''
 if utils.Is_GET(request):
 page_id=str(uuid.uuid4())
 request.session["pageid"]=page_id
 return render_to_response(urlconfig.index,{'form':SupplierForm(),'data':supplier_table_data,'pageId':page_id})
 elif utils.Is_POST(request):
 if utils.GetData(request,'hid')==request.session["pageid"]:
 form_p=SupplierForm(request.POST)
 if SupplierForm.is_valid:
 form_p.save()
 page_id=str(uuid.uuid4())
 request.session["pageid"]=page_id
 return render_to_response(urlconfig.index,{'form':SupplierForm(),'data':supplier_table_data,'pageId':page_id})
 else:
 page_id=str(uuid.uuid4())
 request.session["pageid"]=page_id
 return render_to_response(urlconfig.index,{'form':SupplierForm(),'data':supplier_table_data,'pageId':page_id})
 return render_to_response(urlconfig.index,{'form':SupplierForm(),'data':supplier_table_data,'pageId':page_id})
