Django ModelViewSet。如何合并两个执行方法/功能?

有没有合并执行方法/函数的方法?该视图使用ModelViewSet。我有两个功能 执行创建 和 执行更新 它们做了同样的事情,我想知道我能不能合并它们?

身体

{
    "title": "1 Title",
    "description": "1 Description",
    "author": {
        "id": 1
    }
}

看法

class ArticleView(viewsets.ModelViewSet):
    queryset = Article.objects.all()
    serializer_class = ArticleSerializer

    def perform_create(self, serializer):
        author = get_object_or_404(Author, id=self.request.data['author']['id'])
        return serializer.save(author=author)

    def perform_update(self, serializer):
        author = get_object_or_404(Author, id=self.request.data['author']['id'])
        return serializer.save(author=author)

串行器

class AuthorSerializer(serializers.ModelSerializer):
    class Meta:
        model = Author
        fields = '__all__'


class ArticleSerializer(serializers.ModelSerializer):
    author = AuthorSerializer()

    class Meta:
        model = Article
        fields = '__all__'
