Django NoReverseMatch Reverse for DetailVi

Question

当我重定向回django1.5中的详细视图时，我的应用程序抛出了一个错误。在

NoReverseMatch: Reverse for 'InventoryPlotDetailView' with arguments '(3,)' and keyword arguments '{}' not found.

它得到了正确的forestinventoryplot_id，但是detail视图似乎不知道如何处理这个参数。如果我手动访问detail视图（http://[server]/geoapp/inventory_plot/detail/3/），它将按预期工作。下面是相关的零碎，有什么建议吗？在

视图.py：

class InventoryPlotDetailView(DetailView):
    queryset = ForestInventoryPlot.objects.all()
    template_name = 'geoapp/forestinventoryplot_detail.html'
    context_object_name = 'plot_detail'

def InventoryDataAdd(request, forestinventoryplot_id=1):
    if request.method == 'POST': 
        form = InventoryDataForm(request.POST) 
        if form.is_valid(): 
            new_data = form.save()          
            return HttpResponseRedirect(reverse('geoapp:InventoryPlotDetailView', args=(new_data.forestinventoryplot_id,)))
    else: 
        initial_data = {'forestinventoryplot' : forestinventoryplot_id}
        form = InventoryDataForm(initial=initial_data)    
        return render(request, 'geoapp/forestinventorydata_add.html', {'form': form})

网址.py：

模型.py：

class ForestInventoryPlot(models.Model):
    forestinventoryplot_id = models.AutoField(primary_key=True)
    plot_area_ft2 = models.DecimalField(null=True, blank=True, max_digits=5, decimal_places=1)

视图需要将主键作为kwarg传递，并使用网址.py条目（plot_detail），并使用附加到它的名称空间（'geoapp：绘图详情'使事情运转起来。在

def InventoryDataAdd(request, forestinventoryplot_id=1):
    if request.method == 'POST':
        form = InventoryDataForm(request.POST) 
        if form.is_valid(): 
            new_data = form.save()
            return HttpResponseRedirect(reverse('geoapp:plot_detail', kwargs={'pk':new_data.forestinventoryplot_id}))
        else: 
            initial_data = {'forestinventoryplot' : forestinventoryplot_id}
            form = InventoryDataForm(initial=initial_data)
    return render(request, 'geoapp/forestinventorydata_add.html', {'form': form})
