class GetUserImageOneSerializer(serializers.ModelSerializer):

在這里，我試圖在聊天序列化程式（'ChatImage'）中傳遞用戶的影像。為了在 UI 中獲得更好的行為，我需要方形裁剪影像，所以我嘗試使用嵌套序列化程式（'ChatUserSerializer' 中的'GetUserImageOneSerializer'）。但我只得到正常的 URL。你能幫我找到更好的方法來實作我的想法嗎:)
輸出 ：
[
{
"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"
}
}
]

我得到了解決方案
我在影像序列化器中犯了錯誤它應該是這樣的
class GetUserImageOneSerializer(serializers.ModelSerializer):
image_one = VersatileImageFieldSerializer(
sizes=[
('medium_square_crop', 'crop__400x400'),
]
)
class Meta:
model = UserImage
fields = ('image_one',)
