使用Django显示视图中的对象的属性

Question

我正在使用Django 1.9。我想显示一个包含保存在数据库中的特定车辆属性的视图。但是，当我尝试访问视图时，我收到属性错误而不是车辆特征列表。我应该修正哪些数据，以便正确显示每辆车的视图？每辆车都有一个身份证，而我的数据库中只有一辆车（所以我将该车的身份证放入我的网址中）。在此先感谢

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..
