Eu tenho um modelo de comentário que quando criado pode ou não criar um novo usuário. Por esse motivo, minha API requer um campo de senha ao criar um novo comentário. Aqui está o meu modelo de comentário:

class Comment(models.Model):
    commenter = models.ManyToManyField(Commenter)
    email = models.EmailField(max_length=100)
    author = models.CharField(max_length=100)
    url = models.URLField(max_length=200)
    content = models.TextField(blank=True, null=True)
    ip = models.IPAddressField(max_length=45)
    date = models.DateTimeField(default=datetime.now)
    post_title = models.CharField(max_length=200)
    post_url = models.URLField(max_length=200)
    rating = models.IntegerField(max_length=10, default=0)

Aqui está a minha visualização da API:

class CommentNewView(CreateAPIView):
    model = Comment
    serializer_class = CommentCreateSerializer

Aqui está o meu serializador:

class CommentCreateSerializer(serializers.ModelSerializer):
    commenter_pw = serializers.CharField(max_length=32, required=False)

    class Meta:
        model = Comment
        fields = ('email', 'author', 'url', 'content', 'ip', 'post_title', 'post_url', 'commenter_pw')

Aqui está o erro que estou recebendo:
