js前端动态生成变量及python后端动态生成变量接收

前端代码：

 let sbmt = function(data){
         layui.use('layer', function() {
             var layer = layui.layer;
             $.ajax({
                 url: "{% url 'cutover:maintain' %}",
                        data: data,
                        dataType: 'json',
                        type: 'post',
                        traditional: true,
                        success: function (data) {
                           if (data.status == 1) {
                               console.log(data.msg);
                               //发异步，把数据提交给Python
                                layer.alert(data.msg, {icon: 1}, function () {
                                     let index = parent.layer.getFrameIndex(window.name);
                                        //关闭当前frame
                                     parent.layer.close(index);
                                     parent.window.location.reload();
                                }, 1000);

python 后端动态生成变量接收代码：

def maintain(request):
	id = request.POST.get('id')
        cut_obj = cutover.objects.filter(id=id).first()
        cks = cut_obj.checknode_set.all()
        level_type = request.POST.get('level_type')
        staging = int(request.POST.get('staging',0))
        bf,af = {},{}

        if int(level_type) in (2,3):
            for node in cks:
                bf['bf'+str(node.id)] = request.POST.get('bf'+str(node.id))
                af['af'+str(node.id)] = request.POST.get('af{}'.format(node.id))
                CheckNode.objects.filter(cutover=cut_obj,id=node.id).update(
                    cutover_before=bf['bf'+str(node.id)],
                    cutover_after=af['af'+str(node.id)],
                    staging=staging
                )
        data = {
            'msg':'保存成功',
            'status':1
        }

        return JsonResponse(data)
