“此欄位是必需的。”Django休息框架

我查看了堆疊中的每個答案，但找不到答案。我用 django rest 框架創建了一個 API，并進行了一些測量。我試圖通過郵遞員或 django API 發布 TreeSensor 測量值。天氣測量值作業得很好，但在我的 TreeSensor 上我得到以下錯誤，即使它們除了欄位之外是相同的。

{
    "soil_moisture_depth_1": [
        "This field is required."
    ],
    "soil_moisture_depth_2": [
        "This field is required."
    ]  }

序列化器：

class TreeSensorMeasurementSerializer(serializers.ModelSerializer):
    class Meta:
        model = TreeSensorMeasurement
        fields = ["sensor", "datetime", "soil_moisture_depth_1","soil_moisture_depth_2","soil_moisture_depth_1_filtered","soil_moisture_depth_2_filtered", "soil_temperature"]

class WeatherStationMeasurementSerializer(serializers.ModelSerializer):
    class Meta: 
        model = WeatherStationMeasurement
        fields = ["sensor", "datetime", "wind_speed", "current_rain", "wind_direction", "solar_radiation", "air_temperature", "air_humidity", "air_pressure", "luminosity", "battery", "dew_point"]

介面：

    def post(self,request, *args, **kwargs):

        data = {
            'sensor' : request.data.get('sensor'),

uj5u.com熱心網友回復：

我認為發生錯誤是因為您更改了欄位名稱。

########### TreeSensorMeasurement Api ###########
def post(self,request, *args, **kwargs):

    data = {
        'sensor' : request.data.get('sensor'),
        'datetime' : request.data.get('datetime'),
        # Here I changed the field names
        'soil_moisture_depth_1' : request.data.get('soil_moisture_depth_1'),
        'soil_moisture_depth_2' : request.data.get('soil_moisture_depth_2'),
        'soil_moisture_depth_1_filtered' : request.data.get('soil_moisture_depth_1_filtered'),
        'soil_moisture_depth_2_filtered' : request.data.get('soil_moisture_depth_2_filtered'),
        'soil_temperature' : request.data.get('soil_temperature'),
    }
    serializer = TreeSensorMeasurementSerializer(data=data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status = status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

soi_...欄位名稱應更改soil_...為.

希望它可以幫助。
