在Django Rest Framework中，如何将值序列化为值数组而不是对象数组？以下是我的序列化代码示例：

class NodeTagSerializer(serializers.ModelSerializer):
    class Meta:
        model = NodeTag
        fields = (
            'name',
        )


class NodeTreeSerializer(serializers.ModelSerializer):
    tags = NodeTagSerializer(required=False)

    class Meta:
        model = NodeTree
        fields = (
            'tags',
        )

这是回归：

"tags": [
    {"name": "Tag1"},
    {"name": "Tag2"}
]

但我想要：

"tags": [
    "Tag1",
    "Tag2"
]

        return obj.name

在v3中，这个问题的答案发生了变化。新方法是：

class NodeTagSerializer(serializers.ModelSerializer):
  def to_representation(self, obj):
      return obj.name
