使用Django顯示視圖中的對象的屬性

Question

我正在使用Django 1.9。我想顯示一個包含保存在數據庫中的特定車輛屬性的視圖。但是，當我嘗試訪問視圖時，我收到屬性錯誤而不是車輛特徵列表。我應該修正哪些數據，以便正確顯示每輛車的視圖？每輛車都有一個身份證，而我的數據庫中只有一輛車（所以我將該車的身份證放入我的網址中）。在此先感謝

views.py

def getAuto(request, idAuto): 
    auto = Auto.objects.get(idAuto=idAuto) 
    ctx = {"auto": auto} 
    return render('vehiculo_especifico.html', ctx) 

urls.py

url(r'^verAuto/(?P<idAuto>\d+)/$', views.verAuto), 

models.py

class Auto(models.Model): 
    idAuto = models.AutoField(primary_key=True) 
    Marca = models.CharField(max_length=45) 
    Modelo = models.CharField(max_length=45) 
    VarianteModelo = models.CharField(max_length=45) 
    Ano = models.IntegerField(null=False, default=2016) 
    etc..
