我想讓用戶能夠在 Django Rest API 中使用 PUT 請求僅更新某些屬性。舉個例子，如果我有以下模型并且只希望用戶能夠更新他們的名字和姓氏，我將如何去做呢？models.py:class User(models.Model): email = models.EmailField('email address', unique = True) first_name = models.TextField(max_length = 10) last_name = models.TextField(max_length = 20)（請注意，他們不應該能夠更改自動設置的“id”字段）serializers.py:class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['id', 'email', 'first_name', 'last_name']views.py:class SingleUser(APIView): def put(self, request, user_id): user = User.objects.get(pk = user_id) serializer = UserEditSerializer(user, data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status = status.HTTP_200_OK) return Response(serializer.errors, status = status.HTTP_400_BAD_REQUEST)強制用戶只能更改這些屬性的子集的最佳方法是什么？

您可以在序列化器上設置只讀字段：
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ['id', 'email', 'first_name', 'last_name']
read_only_fields = ['id', 'email']
確保在 put 函數中將序列化器設置為部分：
serializer = UserEditSerializer(user, data = request.data, partial=True)
您還可以完全省略序列化程序中的字段，這將使用戶根本無法使用這些字段。

創(chuàng)建一個單獨的序列化器并使用它
# serializers.py
class UserPutSerializer(serializers.ModelSerializer): # new serializer class
class Meta:
model = User
fields = ['first_name', 'last_name'] # define required fields
#views.py
class SingleUser(APIView):
def put(self, request, user_id):
user = User.objects.get(pk=user_id)
serializer = UserPutSerializer(user, data=request.data) # use new serializer here
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_200_OK)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
