Django 无法在 SerializerMethodField() 中 retrieve/fetch versatileImage link (Cropped 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

这里我试图在聊天序列化器 ('ChatImage') 中传递用户图像。为了在 UI 中获得更好的行为，我需要方形裁剪图像，所以我尝试使用嵌套序列化器 ('GetUserImageOneSerializer' 在 'ChatUserSerializer' 内）。但我只是变得正常 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"
        }
    }
]

我得到了解决方案

我在图像序列化器中出错它应该看起来像这样

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