ValidationError:在Django中不是有效的UUID

我正在使用Django 2.0

我有一张

Note

表格和

StarredNotes

表格

最初，没有

id

字段，因为它是由

Django

作为

integer

数据类型默认添加的

现在我已经将模型中

id

的数据类型更改为

UUID

model.py

class Starred(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    note = models.ForeignKey(Note, on_delete=models.CASCADE)

    objects = StarredManager()

class ColorLabels(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    title = models.CharField(max_length=100, unique=True)
    value = models.CharField(max_length=100)
    default = models.BooleanField(default=False)
    updated = models.DateTimeField(auto_now=True)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title + '(' + self.value + ')'

class StarredNotes(ListView):
    template_name = 'notes/starred.html'
    model = Starred
    context_object_name = 'starred_notes'

    def get_queryset(self):
        starred_notes = Starred.objects.filter(user=self.request.user).order_by('-updated')
        return starred_notes

    @method_decorator(login_required)
    def dispatch(self, request, *args, **kwargs):
        return super(self.__class__, self).dispatch(request, *args, **kwargs)

app_name = 'notes'
urlpatterns = [
    url(r'^$', MyNotes.as_view()),
    url(r'^my/$', MyNotes.as_view(), name='my'),
    path('<pk>/', NoteUpdate.as_view(), name='update'),
    path('share-public/<pk>/', ShareNotePublic.as_view(), name='share-public'),

    path('new/', NewNote.as_view(), name='new'),
    path('<pk>/public/', PublicNoteView.as_view(), name='public-view'),
]

和视图.py

class Starred(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    value = models.CharField(max_length=100)
    default = models.BooleanField(default=False)
    updated = models.DateTimeField(auto_now=True)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):

    template_name = 'notes/starred.html'
    model = Starred

        return starred_notes

    @method_decorator(login_required)
    def dispatch(self, request, *args, **kwargs):

    path('new/', NewNote.as_view(), name='new'),
    path('<pk>/public/', PublicNoteView.as_view(), name='public-view'),
]

和url.py

class Starred(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    default = models.BooleanField(default=False)
    updated = models.DateTimeField(auto_now=True)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):

class StarredNotes(ListView):
    template_name = 'notes/starred.html'
    model = Starred
    context_object_name = 'starred_notes'

    def get_queryset(self):
        starred_notes = Starred.objects.filter(user=self.request.user).order_by('-updated')
        return starred_notes

    @method_decorator(login_required)
    def dispatch(self, request, *args, **kwargs):
        return super(self.__class__, self).dispatch(request, *args, **kwargs)

app_name = 'notes'

    path('new/', NewNote.as_view(), name='new'),
    path('<pk>/public/', PublicNoteView.as_view(), name='public-view'),
]

它给出的错误为

["'starred-notes' is not a valid UUID."]
