Django Rest框架返回 "detail": "Not found."

Question

当我尝试进行获取或部分更新时，我有一个 API 端点出现问题。我不确定我错过了什么，我已将代码包含在尝试及其给出的错误中。

错误:

"detail": "Not found."

据我了解，url 应该包含我想要部分更新的实例的 ID，因此执行 PATCH 的 url 是:

http://localhost:8000/manuscripts-api/manuscriptlibrary/9/

我的看法:

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:

网址:

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

返回:

[ { "id": 28, "manuscript": 9, "bookmarks": "test success", "history": "test success" } ]

Answer 1

对于修补程序并获取详细信息，您需要使用 id 中的值，在您的情况下，这是 28，尝试转到路径并修补

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