django-rest-framework ModelSerializer fields whose names are invalid Python identifiers

If I have a serializer thus:

class CommentSerializer(serializers.Serializer):
    email = serializers.EmailField()
    content = serializers.CharField(max_length=200)

then the dictionary returned by serializer.data will have keys "email" and "content".

But I need to include fields whose names are not valid Python identifiers:

Is there an idiomatic way of doing this?

try to override to_representation() method in CommentSerializer as,

class CommentSerializer(serializers.Serializer):
    type = serializers.EmailField()
    content = serializers.CharField(max_length=200)

    def to_representation(self, instance):
        data = super().to_representation(instance)
        return_data = {}
        return_data.update({"type": data['type'], "@context": data['content']})
        return return_data



EX:

In [2]: mydata = {"type": "[email protected]","content": "some content"}

In [3]: comment = CommentSerializer(data=mydata)

In [4]: comment.is_valid(True)
Out[4]: True

In [5]: comment.data
Out[5]: {'type': '[email protected]', '@context': 'some content'}
