Django Rest Framework 返回"detail"："Not found."

Question

我有一个API端点，当我尝试进行get或部分更新时，它会出现问题。我不确定我缺少什么，我将尝试及其产生的错误包括了代码。

错误：

"细节"："找不到。"

据我了解，据我了解，URL应该包括我要部分更新的实例的ID，因此在IS上执行补丁的URL：

http：//localhost：8000/Manuscripts-api/ManuscriptLibrary/9/

我的观点：

class ManuscriptLibraryViewSet(viewsets.ModelViewSet):
    """Handles creating, reading and updating manuscript library."""
    authentication_classes = (TokenAuthentication,)
    serializer_class = serializers.ManuscriptLibrarySerializer
    queryset = models.ManuscriptLibrary.objects.all()
    permission_classes = (permissions.PostOwnManuscriptLibrary,)
    def put(self, request, *args, **kwargs):
        return self.partial_update(request, *args, **kwargs)

我的模型：

class ManuscriptLibrary(models.Model):
    """Represents a single manuscript's library"""
    manuscript = models.OneToOneField(ManuscriptItem, on_delete=models.CASCADE)
    bookmarks = models.CharField(max_length=99999999)
    history = models.CharField(max_length=99999999)
    def __str__(self):
        """Django uses when it needs to convert the object to a string"""
        return str(self.manuscript)

我的序列化器：

class ManuscriptLibrarySerializer(serializers.ModelSerializer):
    """A serializer for a manuscript's library."""
    class Meta:
        model = models.ManuscriptLibrary
        fields = ('id', 'manuscript', 'bookmarks', 'history')

我的网址：

router = DefaultRouter()
router.register('manuscripts', views.ManuscriptViewSet, base_name="manuscripts")  # auto basename for models
router.register('manuscriptlibrary', views.ManuscriptLibraryViewSet, base_name="manuscript_library")
router.register('manuscriptsettings', views.ManuscriptSettingsViewSet)
urlpatterns = [
    url(r'', include(router.urls))
]

我的许可：

class PostOwnManuscriptLibrary(permissions.BasePermission):
    """Allow author to update a manuscript's library they own."""
    def has_object_permission(self, request, view, obj):
        if request.method in permissions.SAFE_METHODS:
            return True
        return obj.manuscript.author == request.user
    def has_permission(self, request, view):
        if request.method == 'POST':
            manuscript = request.data.get('manuscript')
            instance = ManuscriptItem.objects.get(pk=manuscript)
            return instance.author == request.user
        return True

其他信息：

url：

http：//localhost：8000/Manuscripts-api/ManuscriptLibrary/

返回：

[ { " id"：28， "手稿"：9， "书签"："测试成功"， "历史"："测试成功" }]

Answer 1

用于补丁程序并获取细节您需要使用id的值，在您的情况下，这是28，尝试转到路径，然后补丁

http://localhost:8000/manuscripts-api/manuscriptlibrary/28/
