Django DRF - api webview 中的 "hide user"（必填字段）

Question

我有一个简单的模型：

class Store(models.Model):
    name = models.CharField("address", max_length = 128, null = True, blank = True)
    open = models.PositiveIntegerField("status", default = 1, choices = [(0,0), (1,1)])
    user = models.OneToOneField(User, on_delete = models.CASCADE, )

使用简单的序列化程序：

class StoreSerializer(serializers.ModelSerializer):
    class Meta:
        model = Store
        fields = ["open", "user"]

观点：

class StateViewSet(viewsets.ModelViewSet):
    serializer_class = StoreSerializer
    http_method_names = ['get', 'put', 'head']
    authentication_classes = [SessionAuthentication,]
    permission_classes = [IsAuthenticated,]

    def list(self, request):
        usr = request.user
        stores = Store.objects.filter(user = usr)
        return Response(stores.values_list("name", flat = True))

    def put(self, request):
        usr = request.user
        Store.objects.filter(user = usr).update(state = request.data["state"])
        return Response("updated")

我想要的是，去掉用户字段——反正只有当前用户可以改变状态，所以它已经是一个预设值了。我知道我省略了名称，因为它是 null = True, blank = True，但是我怎样才能将 user 预设为 request.user 并让下拉列表消失？

Answer 1

您可以在序列化程序的 Meta 选项中设置 read_only_fields class

class StoreSerializer(serializers.ModelSerializer):
    class Meta:
        model = Store
        fields = ["open", "user"]
        <b>read_only_fields = ("user",)</b>

请注意，这只会 exclude/hide 来自 HTML 表格的 user，不会进行预设。
