Question

我有两个网址：

url(r'^eliminar_cliente/(\d+)$', 'apps.Administracion.views.eliminar_cliente',name = 'eliminar_cliente'),
url(r'^eliminar_factura/(\d+)$', 'apps.Administracion.views.eliminar_factura',name = 'eliminar_factura'),

这两个按钮在不同的模板中：

^{pr2}$

最后这两种观点：

def eliminar_cliente(request, id_cliente):
    instance = Cliente.objects.get(pk= id_cliente)
    instance.delete()
    messages.error(request, 'Document deleted.')
    return HttpResponseRedirect('../clientes')

def eliminar_factura(request, id_factura):
    instance = Factura.objects.get(pk = id_factura)
    instance.delete()
    return HttpResponseRedirect('../facturas')

正如你所看到的，它们都是一样的。这是不同模板中的两个不同按钮，它们执行相同的操作：删除账单（fatura在西班牙语中）和删除客户机。在

删除模板的地方我有个错误，就是删除模板

NoReverseMatch at /Exi/ver_Factura/6
Reverse for 'eliminar_factura' with arguments '('',)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['Exi/eliminar_factura/(\\d+)$']

由于两个按钮的功能相同，我不知道为什么会发生这种情况！在

任何帮助都将非常感谢。谢谢

这是呈现按钮所在模板的视图：

@login_required
def ver_Factura(request, id_factura):
    fact = Factura.objects.get(pk = id_factura)
    cliente = Cliente.objects.get(factura = fact)
    template = 'ver_facturas.html'
    iva = fact.importe_sin_iva * 0.21
    total = fact.importe_sin_iva + iva

    extra_context = dict()
    extra_context['fact'] = fact
    extra_context['cliente'] = cliente
    extra_context['iva'] = iva
    extra_context['total'] = total

    return render(request,template, extra_context)

Answer 1

{{cd2>是明显的错误。在

with arguments '('',)' and keyword arguments '{}' ...

为了调试的目的，尝试对ID进行硬编码，我相信它会起作用的。在

^{pr2}$

如果是这样，那么试着找出factura或{}是{}的原因。在

Answer 2

尝试将URL更改为：

url(r'^eliminar_cliente/(?P<id_cliente>\d+)$', 'apps.Administracion.views.eliminar_cliente',name = 'eliminar_cliente'),
url(r'^eliminar_factura/(?P<id_factura>\d+)$', 'apps.Administracion.views.eliminar_factura',name = 'eliminar_factura'),
