django rest框架中的用户外键

我有一个用户模型和Accesskey模型。我想在accesskey表中保存正在访问API（access_key）的用户

型号.py

class AccessKeys(models.Model):
    user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='user',null=True)
    access_keys =models.CharField(max_length=400)


    def __str__(self):
        return self.access_keys

class AccessKeySerializer(serializers.ModelSerializer):
    user_id = serializers.RelatedField(source='CustomUser', read_only=True)
    access_keys = serializers.CharField(max_length=200,required=True)
    class Meta:
        model =AccessKeys
        fields = '__all__'
 

class AccessKeyView(generics.ListCreateAPIView):
    permission_classes = [IsAuthenticated, ]
    queryset = AccessKeys.objects.all()
    serializer_class = AccessKeySerializer

    def post(self,request):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=HTTP_201_CREATED)
        return Response(serializer.errors, status=HTTP_400_BAD_REQUEST)

序列化程序.py

class AccessKeys(models.Model):
    user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='user',null=True)
    access_keys =models.CharField(max_length=400)


    def __str__(self):
        return self.access_keys

class AccessKeySerializer(serializers.ModelSerializer):
    user_id = serializers.RelatedField(source='CustomUser', read_only=True)
    access_keys = serializers.CharField(max_length=200,required=True)
    class Meta:
        model =AccessKeys
        fields = '__all__'
 

class AccessKeyView(generics.ListCreateAPIView):
    permission_classes = [IsAuthenticated, ]
    queryset = AccessKeys.objects.all()
    serializer_class = AccessKeySerializer

    def post(self,request):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=HTTP_201_CREATED)
        return Response(serializer.errors, status=HTTP_400_BAD_REQUEST)

视图.py

class AccessKeys(models.Model):
    user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='user',null=True)
    access_keys =models.CharField(max_length=400)


    def __str__(self):
        return self.access_keys

class AccessKeySerializer(serializers.ModelSerializer):
    user_id = serializers.RelatedField(source='CustomUser', read_only=True)
    access_keys = serializers.CharField(max_length=200,required=True)
    class Meta:
        model =AccessKeys
        fields = '__all__'
 

class AccessKeyView(generics.ListCreateAPIView):
    permission_classes = [IsAuthenticated, ]
    queryset = AccessKeys.objects.all()
    serializer_class = AccessKeySerializer

    def post(self,request):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=HTTP_201_CREATED)
        return Response(serializer.errors, status=HTTP_400_BAD_REQUEST)

当我在模型中保存accesskey时，user\u id字段中有空值。

serializer.save（user=request.user）

非常感谢。它起作用了。@token Views.py`serializer=AccessKeySerializer（request.user）Key=serializer.data.get（'access\u keys'）`当我运行这个时，我得到了一个错误-AttributeError:'RelatedManager'对象没有属性'pk'。请解决这个问题。我正在努力，但无法修复它。
