[django]從前端返回字串,後端轉換為字典,執行資料添加操作

具體如題:

js代碼如下:

$(‘#bill_add‘).click(function(){//合約添加          var bill1 = $("#bill1").val();var bill2 = $("#bill2").val();var bill3 = $("#bill3").val();var bill4 = $("#bill4").val();var bill5 = $("#bill5").val();          var bill6 = $("#bill6").val();var bill7 = $("#bill7").val();var bill8 = $("#bill8").val();var bill9 = $("#bill9").val();var bill10 = $("#bill10").val();          var bill11 = $("#bill1").val();var bill12 = $("#bill12").val();var bill13 = $("#bill13").val();var bill14 = $("#bill14").val();var bill15 = $("#bill15").val();          var bill16 = $("#bill16").val();var bill17 = $("#bill17").val();var bill18 = $("#bill18").val();var bill19 = $("#bill19").val();var bill20 = $("#bill20").val();          var bill21 = $("#bill21").val();var bill22 = $("#bill22").val();var bill23 = $("#bill23").val();var bill24 = $("#bill24").val();var bill25 = $("#bill25").val();          var bill26 = $("#bill26").val();var bill27 = $("#bill27").val();var bill28 = $("#bill28").val();var bill29 = $("#bill29").val();var bill30 = $("#bill30").val();          var bill31 = $("#bill31").val();var bill32 = $("#bill32").val();var bill33 = $("#bill33").val();var bill34 = $("#bill34").val();var bill35 = $("#bill35").val();          var bill36 = $("#bill36").val();var bill37 = $("#bill37").val();var bill38 = $("#bill38").val();var bill39 = $("#bill39").val();var bill40 = $("#bill40").val();          var bill41 = $("#bill41").val();          $.post("{% url ‘add_contract‘ %}",              {                  csrfmiddlewaretoken:"{{ csrf_token }}",                  bill_str:"{‘bill1‘:‘"+bill1+"‘,‘bill2‘:‘"+bill2+"‘,‘bill3‘:‘"+bill3+"‘,‘bill4‘:‘"+bill4+"‘,‘bill5‘:‘"+bill5+"‘,"                          +"‘bill6‘:‘"+bill6+"‘,‘bill7‘:‘"+bill7+"‘,‘bill8‘:‘"+bill8+"‘,‘bill9‘:‘"+bill9+"‘,‘bill10‘:‘"+bill10+"‘,"                          +"‘bill11‘:‘"+bill11+"‘,‘bill12‘:‘"+bill12+"‘,‘bill13‘:‘"+bill13+"‘,‘bill14‘:‘"+bill14+"‘,‘bill15‘:‘"+bill15+"‘,"                          +"‘bill16‘:‘"+bill16+"‘,‘bill17‘:‘"+bill17+"‘,‘bill18‘:‘"+bill18+"‘,‘bill19‘:‘"+bill19+"‘,‘bill20‘:‘"+bill20+"‘,"                          +"‘bill21‘:‘"+bill21+"‘,‘bill22‘:‘"+bill22+"‘,‘bill23‘:‘"+bill23+"‘,‘bill24‘:‘"+bill24+"‘,‘bill25‘:‘"+bill25+"‘,"                          +"‘bill26‘:‘"+bill26+"‘,‘bill27‘:‘"+bill27+"‘,‘bill28‘:‘"+bill28+"‘,‘bill29‘:‘"+bill29+"‘,‘bill30‘:‘"+bill30+"‘,"                          +"‘bill31‘:‘"+bill31+"‘,‘bill32‘:‘"+bill32+"‘,‘bill33‘:‘"+bill33+"‘,‘bill34‘:‘"+bill34+"‘,‘bill35‘:‘"+bill35+"‘,"                          +"‘bill36‘:‘"+bill36+"‘,‘bill37‘:‘"+bill37+"‘,‘bill38‘:‘"+bill38+"‘,‘bill39‘:‘"+bill39+"‘,‘bill40‘:‘"+bill40+"‘,"                          +"‘bill41‘:‘"+bill41+"‘}",              },              function(data,status) { ;                 $(‘#test‘).html(data[‘bill40‘]);              }                                                )      });

 view中代碼:

def add_contract(request):    bill_str = (request.POST[‘bill_str‘])    bill_dic = eval(bill_str)    Bill.objects.create(contract_code=bill_dic[‘bill1‘],contract_name=bill_dic[‘bill2‘],new_flag=bill_dic[‘bill3‘],original_code=bill_dic[‘bill4‘],                        con_type=bill_dic[‘bill5‘],rep_nbr=bill_dic[‘bill6‘],acc_code=bill_dic[‘bill7‘],pstn_count=bill_dic[‘bill8‘],                        pstn_cost=bill_dic[‘bill9‘],remark_one=bill_dic[‘bill10‘],fibeione=bill_dic[‘bill11‘],fibeione_cost=bill_dic[‘bill12‘],                        remark_two=bill_dic[‘bill13‘],fibeitwo=bill_dic[‘bill14‘],fibeitwo_cost=bill_dic[‘bill15‘],remark_three=bill_dic[‘bill16‘],                        cmda_count=bill_dic[‘bill17‘],cmda_cost=bill_dic[‘bill18‘],remark_four=bill_dic[‘bill19‘],qtsl_one=bill_dic[‘bill20‘],                        qtfy_one=bill_dic[‘bill21‘],remark_five=bill_dic[‘bill22‘],qtsl_two=bill_dic[‘bill23‘],qtfy_two=bill_dic[‘bill24‘],                        remark_six=bill_dic[‘bill25‘],qtsl_thr=bill_dic[‘bill26‘],qtfy_thr=bill_dic[‘bill27‘],remark_sev=bill_dic[‘bill28‘],                        qtsl_fou=bill_dic[‘bill29‘],qtfy_fou=bill_dic[‘bill30‘],remark_egh=bill_dic[‘bill31‘],old_charge=bill_dic[‘bill32‘],                        charge=bill_dic[‘bill33‘],deal_type=bill_dic[‘bill34‘],con_age=bill_dic[‘bill35‘],con_eff_date=bill_dic[‘bill36‘],                        con_exp_date=bill_dic[‘bill37‘],con_sign_date=bill_dic[‘bill38‘],con_agent=bill_dic[‘bill39‘],charge_type=bill_dic[‘bill40‘],                        payment=bill_dic[‘bill41‘])    #bill_data = Bill.objects.all    return JsonResponse(bill_dic)

 實際上文章採用的是從前端返回字典的字串形式,例如"{‘a‘:‘a‘}",然後在python中利用eval函數將其轉換為字典形式,然後賦值執行django模型添加資料函數

 這樣可以不用後端request.POST一大堆資料,例如我上面bill1到bill41豈不是要request.POST40次,這樣太麻煩了!
