自定义DetailView之类的函数返回相同的数据集-Django

标签： django django-models django-views

我有一个包含项目列表的视图，并且想要创建这些项目的详细视图，以便我可以更新，启用或禁用项目，但我遇到的问题是无论我使用哪个项目，我总是会获得相同的数据单击以获取详细信息。

我已经在这里多次张贴了此内容，但没有答案，也许我无法解释我的问题。

用于处理详细信息的视图 

def detalle_Items(request, pk):
    model = Transaccion
    template_name = 'inventario/carrito/test-template.html'
    try:

        items_update = Transaccion.objects.filter(activo=True, carrito_id=pk, herramienta_id=pk)
    except Transaccion.DoesNotExist:
        raise Http404()

    return render(request, template_name, {'items_update':items_update})

这是绿色“ actualizar” 按钮

触发函数的地方

无论我按什么按钮，这都是我得到的：

这是我的用于carrito的 views.py 一组功能：

# =========================================================================== #
#   LOGICA PARA CREAR CARRITOS
# =========================================================================== #
# ===================> Logica relacinado con Cortadores <=====================#

def home_carrito(request):
    template_name = 'inventario/carrito/createcarrito.html'
    model  = Carritos

    carritos = Carritos.objects.all()
    if carritos:
        return render(request, template_name, {'carritos':carritos})
    else:
        return render(request,template_name)


class CarritoCreate(CreateView):
    model = Carritos
    fields = [
        'no_carrito',
        'empleado',
        'activo',
    ]

class ItemCreate(CreateView):
    model = Transaccion
    fields = [
        'carrito',
        'herramienta',
    ]


def detalle_carrito(request, pk):
    model = Carritos, Transaccion
    template_name = 'inventario/carrito/detalles_carrito.html'

    carritos = Carritos.objects.filter(pk=pk)
    # GEST ALL TOOLS ASSIGN TO CARRITO'S PK THAT ARE ACTIVE 
    # TRY TO GET ALL ACTIVE ITEMS THAT BELONG TO CARRITO = PK AND AGREGATE TOTAL ITEMS PER TYPE
    cantidades = Transaccion.objects.values('herramienta__description').annotate(Sum('cantidad')).filter(activo=True, carrito_id=pk)

    # GEST ALL TOOLS ASSIGN TO CARRITO'S PK THAT ARE NOT ACTIVE 
    eliminados = Transaccion.objects.filter(activo=False,carrito_id=pk)

    return render(request,template_name, {'carrito':carritos, 'trans':cantidades, 'eliminados':eliminados})



class CarritoUpdate(UpdateView):
    model = Carritos
    fields = [
        'no_carrito',
        'empleado',
        'activo',
    ]
    template_name_suffix = '_update_form' 




def detalle_Items(request, pk):
    model = Transaccion
    template_name = 'inventario/carrito/test-template.html'
    try:

        items_update = Transaccion.objects.filter(activo=True, carrito_id=pk, herramienta_id=pk)
    except Transaccion.DoesNotExist:
        raise Http404()

    return render(request, template_name, {'items_update':items_update})


class ItemUpdate(UpdateView):
    model = Transaccion
    fields = [
        'carrito',
        'herramienta',
        'cantidad',
        'tipo',
        'motivo',
        'activo',
    ]
    template_name_suffix = '_update_form' 


class ItemDelete(DeleteView):
    model = Transaccion
    success_url = reverse_lazy('item-herramienta')

这些是我对carritos的 models.py ：

# =========================================================================== #
#   MODELO PARA CREAR CARRITOS

class Carritos(models.Model):
    no_carrito = models.CharField(max_length=3, unique=True)
    empleado = models.OneToOneField(Empleados, on_delete=models.CASCADE)
    # empleado = models.ManyToManyField(Empleados,  through='Transaccion')
    items = models.ManyToManyField(Item, through='Transaccion', related_name='carritos')
    f_creacion = models.DateTimeField(auto_now_add=True)
    f_actualizacion = models.DateTimeField(auto_now=True)
    activo = models.BooleanField(default=True)

    def get_absolute_url(self):
        return reverse('inventario:carrito')#, kwargs={'pk': self.pk})


    class Meta:
        verbose_name_plural = "Carritos"

    def __str__(self):
        return self.no_carrito



class Transaccion(models.Model):

    carrito = models.ForeignKey(Carritos, on_delete=models.CASCADE, related_name='items_carrito')
    herramienta = models.ForeignKey(Item, on_delete=models.CASCADE, related_name='items_carrito')
    cantidad = models.PositiveSmallIntegerField(default=1)
    activo = models.BooleanField(default=True)
    tipo = models.CharField(max_length=10, choices=CONSUMIBLE, blank=True, null=True)
    motivo = models.CharField(max_length=10, blank=True, null=True)


    def get_absolute_url(self):
        return reverse('inventario:carrito')#, kwargs={'pk': self.pk})
