*** AttributeError：模型对象没有属性

Question

我有一个像下面的Python Django models.py -

class Nx2FwComponent(models.Model):
    name = models.CharField(max_length=10)

    def __unicode__(self):
        return self.name

 class Nx2FwComponentWithPath(models.Model):
    nx2FwComponent = models.ForeignKey(Nx2FwComponent)
    path = models.CharField(max_length=100, unique=True)
    def __unicode__(self):
        return (self.path + '/' + str(self.nx2fwComponent))

如图所示填充数据库表 -

sqlite> select * from config_nx2fwcomponent;
1|mfw
2|mba
3|feb
4|ib_ipv4n6
sqlite> select * from config_nx2fwcomponentwithpath;
1|V:\rels\mba|2

在我的views.py中，当我跑 -

时

Nx2FwComponentWithPath.objects.all()

我收到此错误 -

(Pdb) Nx2FwComponentWithPath.objects.all()
*** AttributeError: 'Nx2FwComponentWithPath' object has no attribute 'nx2fwComponent'

有什么问题？
