Hi Glenn,
You can make use of the `write_only` and `read_only` field arguments, in
addition to `source`. eg, you should be able to do:
class StorySerializer(serializers.ModelSerializer):
post_content = serializers.CharField(write_only=True, source='content')
content = serializers.CharField(read_only=True)
That said, I'd argue against this, as it's kind of unexpected that you
would create content with one name, and then read it from another. I would
recommend just aliasing the `content` field as `post_content` in the
serializer.
class StorySerializer(serializers.ModelSerializer):
post_content = serializers.CharField(source='content')
Best,
Ryan
