我有兴趣从views.py以JSON格式获取插入操作的结果。我想,我的结果还不错。我的观点如下:

added={}
if request.method=='POST':
        #Post method initiated.

        try:
            for id in allergies:
                   allergy=PatientAllergy(patient=patient,allergy_id=id,addedby=request.user)
               allergy.save()
               added[allergy.id]=id
        except BaseException as e:
            pass

return JsonResponse(added,safe=False)

从JQUERY传递的记录成功添加到数据库中。我现在想要的是{12:1,13:2}形式的JSON结果。

我的火袋显示响应:

    12:1
    13:2

我不确定这是否是一个有效的JSON。如果我列出(添加),它会改为:

    0: 12
    1: 13
我不想要的。我现在遇到的问题我想通过退回的项目,但我收到不正确的结果。我基本上想要得到12:1,13:2。

         $.ajax({
            type: "POST",
            url: "/patient/addallergy/",
            data: postForm,
            dataType : "json",
            cache: "false",
            success: function (result) {

                    alert(result.length); //gives undefined, rendering the below line meaningless

                    if (result.length>0){


                        $.each(result,function(key,value){
                            alert(key);
                            alert(value);

                           });

                    }


            },
            fail: function (result){

            }


        });

改变你的观点。

added_list=[]
    if request.method=='POST':
            #Post method initiated.

            try:
                for id in allergies:
                   added ={}                  allergy=PatientAllergy(patient=patient,allergy_id=id,addedby=request.user)
                   allergy.save()
                   added[allergy.id]=id
                   added_list.append(added)
            except BaseException as e:
                pass

    return JsonResponse(added_list,safe=False)

和jquery

$.ajax({
        type: "POST",
        url: "/patient/addallergy/",
        data: postForm,
        dataType : "json",
        cache: "false",
        success: function (result) {

                alert(result.length); //gives undefined, rendering the below line meaningless

                if (result.length>0){

                     alert(JSON.stringify(result))
                    $.each(result,function(index,value){
                        console.log(value);



                       });

                     result.forEach( function (eachObj){
                       for (var key in eachObj) {
                                  alert(key);
                             alert(eachObj[key])
                            }
                       });

                }


        },
        fail: function (result){

        }


    });
