No

Note: you use 'ReadOnlyField' argument type is error, case modules call of django is incorrect

Hello,

Thanks for responding. I am not sure where in the code this is coming from. I have this code in my view. Not sure if this is the culprit. If it is, what is a better way to access this data.

class UserPrefSerializer(serializers.ModelSerializer):
    class Meta:
        owner = serializers.ReadOnlyField(source='owner.username')
        model = UserPrefs
        fields = (owner, 'name', 'value')
        depth = 1

If I change this to

    class Meta:
        owner = serializers.ReadOnlyField(source='owner.username')
        

model = UserPrefs
        fields = ('owner', 'name', 'value')
        depth = 1

I get a error: {"value":["This field is required."]}
