Write only fields

[mars...@poundpay.com]

I did some googling but didn't find any results.

Is it possible to have write only fields? E.g. I want the serializer to validate some data in the payload but I don't want to echo that back.

E.g. a password field shouldn't be echoed back:

class UserLoginsSerializer(serializers.Serializer):

    email_address = serializers.EmailField(required=True)

    password = serializers.CharField(required=True, write_only=True)

Yep, that's not quite as simple but it will work. Thanks!

Another option is to override "def data" to delete it from the serialized data:

class MySerializer(serializers.HyperlinkedModelSerializer):

   write_only_field = erializers.WritableField(source='my_field_in_model', required=False)

    @property

    def data(self):

        d = super(MySerializer, self).data

        del d['write_only_field']

        return d

I had the same problem. Here is how I solved it:

class UserSerializer(serializers.HyperlinkedModelSerializer):

    created_at = serializers.Field(source='date_joined')

    class Meta:

        model = User

        fields = ['id', 'url', 'username', 'password', 'first_name', 'last_name', 'email', 'created_at', ]

    def restore_object(self, attrs, instance=None):

        user = super(UserSerializer, self).restore_object(attrs, instance)

        user.set_password(attrs['password'])

        return user

    def to_native(self, obj):

        ret = super(UserSerializer, self).to_native(obj)

        del ret['password']

        return ret
