Question

我正在尝试从object (foto)删除Album，我希望views返回detail view（当前相册），但我无法设置{{1}当前专辑。我尝试了各种各样的方法，但我无法弄清楚并解决它。也许我应该为foto的对象添加一些独立的pk，或者使用一些通常的定义代替泛型foto_pk？我没有想法。请给我一些线索......谢谢。

网址：

DeleteView

查看：

url(r'^$', views.IndexView.as_view(), name='index'),

url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),

url(r'albumadd/$', views.AlbumCreate.as_view(), name='album-add'),

url(r'update/(?P<pk>[0-9]+)/$', views.AlbumUpdate.as_view(), name='albumbum-update'),

url(r'delete/(?P<pk>[0-9]+)/$', views.AlbumDelete.as_view(), name='albumbum-delete'),

url(r'^(?P<pk>[0-9]+)/fotoadd/$', views.FotoCreate.as_view(), name='foto-add'),

url(r'^(?P<pk>[0-9]+)/fotodelete/$', views.FotoDelete.as_view(), name='foto-delete'),

其他尝试观点：

class FotoDelete(LoginRequiredMixin, DeleteView):
    model = Foto

    def album(request, pk):
        album = Album.objects.get(pk=pk)
        return reverse_lazy('albumbum:detail', kwargs={'pk': album.pk})

其他尝试观点：

class FotoDelete(LoginRequiredMixin, DeleteView):
    model = Foto
    success_url = reverse_lazy('albumbum:detail', kwargs={'pk': Album.pk})

我还附加了foto的CreateView（相册中的对象）：（也许这里有一些问题）

class FotoDelete(LoginRequiredMixin, DeleteView):
    model = Foto
    album = get_object_or_404(Album, pk=pk)
    success_url = reverse_lazy('albumbum:detail', kwargs={'pk': album.pk})

models.py

class FotoCreate(CreateView):
    model = Foto
    fields = ['nazwa_foto', 'obraz']

    def form_valid(self, form):
        f = Album.objects.get(pk=self.kwargs.get('pk'))
        form.instance.albumnr = f
        return super(FotoCreate, self).form_valid(form)

    def get_success_url(self):
        return reverse('albumbum:detail', kwargs={'pk': self.kwargs.get('pk')})

Answer 1

试试这个，它应该有效。

@spselectvalue nvarchar(MAX),

// Select multiple Ids based on multiple items from list box

DECLARE @Dis TABLE (DisID int)

INSERT INTO @Dis 
    SELECT DId 
    FROM [table name] 
    WHERE [COLUMN] IN ('+@spselectvalue +')

EXEC sp_executesql @Dis

// Insert multiple Ids (from above select statement) into different table
INSERT INTO [dbo].[DifferentTable] ([SelectedIds])
VALUES
(
    (SELECT DisID from @Dis)
)

Answer 2

也有效：

=(UNIX + ("1/1/1970"-"1/1/1900"+1)*86400) / 86400

在genericView中设置当前的专辑'pk'
