Json的反序列化没有验证

Question

我在我的模板中使用JavaScript制作表格。我决定通过JSON交换数据。请求信息和构建表有效，但序列化程序不会验证发送回服务器的JSON数据。

我正在使用Django REST Framework和JQuery。

我的观点

def get_CEMatrix(request, id):
    if request.method == 'GET':
        Cells = CellCE.objects.filter(project=id).order_by('id')
        serializer = CellCESerializer(Cells, many=True)
        return JsonResponse(serializer.data, safe=False)

    elif request.method == 'POST':
        data = JSONParser().parse(request)
        serializer = CellCESerializer(data=data, many = True)
        if serializer.is_valid():
            serializer.save()
            return JsonResponse(serializer.data, safe=False)
        return JsonResponse(serializer.data, safe=False)

我的JS

alert(JSON.stringify(myRows));
$.ajax({
    "type": "POST",
    "dataType": "json",
    "url": get_CEMatrix,
    "data": JSON.stringify(myRows),
    "success": function(result) {
        alert("success of message to server and result is: " + result);
    }
});

串行

class CellCESerializer(serializers.ModelSerializer):
    row = serializers.StringRelatedField()
    val = serializers.ListField()

    class Meta:
        model = CellCE
        fields = ('row','val')

为模型

class CellCE(models.Model):
    project = models.ForeignKey('Project', on_delete=models.CASCADE, default='1')
    row = models.ForeignKey('Descriptor', on_delete=models.CASCADE)
    val = ArrayField(ArrayField(models.IntegerField(blank=True, default=0)))

我已经实现了一个功能来显示模板中交换的JSON数据。服务器像这样发送JSON：

[
{
"row":"THIS IS AMAZING",
"val":[[139,
144,147],[0,0,0]]
},
{
"row":"HOLY FUCKING MOLY",
"val":[[139,
144,147],[0,0,0]]
},
{
"row":"OMG",
"val":[[139,
144,147],[0,0,0]]
}
]

发送到服务器的JSON看起来像这样。

[
{
},
{
"row":"THIS IS AMAZING",
"val":"139 144 147 "
},
{
"row":"HOLY FUCKING MOLY",
"val":"139 144 147 "
},
{
"row":"OMG",
"val":"139 144 147 "
}
]

序列化程序是否按我认为的方式工作，或者发回的JSON格式不够好。

我愿意接受任何建议。

如果需要，整个JS

// TABLE FUNCION
$(document).ready(function(){
        // CREATE DYNAMIC TABLE.
        var table = document.createElement("table");

        // CREATE HTML TABLE HEADER ROW USING THE EXTRACTED HEADERS ABOVE.
        var tr = table.insertRow(-1);
        // TABLE HEADER
        for (var i = -1; i < descriptornamelist.length; i++) {
          var th = document.createElement("th");
          if (i==-1) {
            th.innerHTML = "Descriptors";
            tr.appendChild(th);
          }
          else {
            th.innerHTML = descriptornamelist[i];
            tr.appendChild(th);
          }
        }

        // ADD JSON DATA TO THE TABLE AS ROWS.
        //First Load with 1 Complete set of Data
        $.getJSON( get_CEMatrix , function(result){
          $.each(result, function(index, field){
            tr = table.insertRow(-1);

            //First COL with Descriptornames
            var tabCell = tr.insertCell(0);
            tabCell.innerHTML = field["row"];

             //Other COLs with Values
            for (var i = 0; i < descriptoridlist.length; i++) {
              var tabCell = tr.insertCell(-1);
              tabCell.contentEditable = true; //change to 1 vor actual values
              tabCell.innerHTML = field["val"][0][i]; //change to 1 vor actual values
            };

          });
        });

        // FINALLY ADD THE NEWLY CREATED TABLE WITH JSON DATA TO A CONTAINER.
        var divContainer = document.getElementById("CETable");
        divContainer.innerHTML = "";
        divContainer.appendChild(table);
});


//BUTTON FOR JSON TO SERVER
$(".table_to_JSON").click(function(){
  var myRows = [];

  // Loop through grabbing everything
  var $rows = $("tbody tr").each(function(index) {
    $cells = $(this).find("td");


    myRows[index] = {};

        $cells.each(function(cellIndex) {
            // Set the header text
              if( cellIndex == 0) {
                  myRows[index]["row"] = $(this).text();
              }
              if( cellIndex > 0) {
                if(myRows[index]["val"] === undefined){
                    myRows[index]["val"] =("");
                }
                myRows[index]["val"] += $(this).text() + (" ");

              }
        });

    });


alert(JSON.stringify(myRows));
$.ajax({
    "type": "POST",
    "dataType": "json",
    "url": get_CEMatrix,
    "data": JSON.stringify(myRows),
    "success": function(result) {
        alert("success of message to server and result is: " + result);
    }
  });
});
