Django无法在versatileImage ()中检索/获取SerializerMethodField链接(裁剪URL)

Question

class GetUserImageOneSerializer(serializers.ModelSerializer):
    class Meta:
        image_one = VersatileImageFieldSerializer(
        sizes=[
            ('medium_square_crop', 'crop__400x400'),
        ]
        )
        model = UserImage
        fields = ('image_one',)

class ChatUserSerializer(serializers.ModelSerializer):
      chatImage = serializers.SerializerMethodField()
      class Meta:
          model = Chat
          fields = ('roome_name','chat_user_one','chat_user_two','lastUpdated','chatImage')
      def get_chatImage(self, obj):
          image=UserImage.objects.filter().first() //(for Test) 
          serializer = GetUserImageOneSerializer(image)
          return serializer.data

在这里，我试图在聊天序列化程序('ChatImage') .For中传递用户的图像--在UI中--我需要方形裁剪图像--所以我尝试使用嵌套序列化器(‘ChatUserSerializer’中的‘GetUserImageOneSerializer’)。但我只得到正常的URL。你能帮我找到更好的方法来实现我的想法吗:)

输出：

[
    {
        "roome_name": "BISM1000BISM1000",
        "chat_user_one": 6,
        "chat_user_two": 5,
        "lastUpdated": "2021-12-11T10:29:21.589947Z",
        "chatImage": {
            "image_one": "/media/userimage/team-1.jpg"
        }
    }
]

我找到解决办法了

我在图像序列化程序中犯了错误，应该是这样的

class GetUserImageOneSerializer(serializers.ModelSerializer):
    image_one = VersatileImageFieldSerializer(
        sizes=[
            ('medium_square_crop', 'crop__400x400'),
        ]
        )
    class Meta:
        model = UserImage
        fields = ('image_one',)
