"This field is required." Django rest framework-CodePudding

I've looked every answer in stack I cant find an answer. I 've created an API with django rest framework with some measurements . Im trying to post a TreeSensor measurement through postman or django API .Weather measurements works just fine but on my TreeSensor i get the following error even though they are identical besides the fields.

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

Serializers :


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"]

CodePudding user response：

I think the error occurred because you had changed the field names.

    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'),

The soi_... field names should be changed into soil_....

Hope it could help.
