Django 1.5类Meta没有属性“verbose_name_plural”

Question

我已经将我的项目从Django1.3升级到了Django1.5，但是出现了一个错误"AttributeError: class Meta没有属性'verbose_name_plural'“

基类

class PortalModelBase(models.base.ModelBase):
   def __new__(cls, name, bases, attrs):
        attr_meta = attrs.pop('Meta', None)

        try:
           is_global = attr_meta.is_global
           del attr_meta.is_global
        except AttributeError:
           is_global = False

        attrs['Meta'] = attr_meta
        model = super(PortalModelBase, cls).__new__(cls, name, bases, attrs)
        model._meta.is_global = is_global
        return model

class Meta:
    abstract = True

模型类

将元类作为PortalModelBase

class PortalModel(models.Model):  
   __metaclass__ = PortalModelBase

    name = models.CharField(max_length=255, verbose_name='name*', help_text='Enter Name', blank=False)
    description = models.CharField(max_length=1024, verbose_name='Description', help_text="Enter a description", blank=True,null=True, default='')
   createdby = models.CharField(max_length=128)
   createdon = models.DateTimeField()
   modifiedby = models.CharField(max_length=128)
   modifiedon = models.DateTimeField()


  def __init__(self_, *args, **kwargs):
    log.info("Portal model initializing")
    if kwargs:
        d = copy.copy(kwargs)
        for key in d:

            if key not in self_._meta.get_all_field_names():
                #The key given by the dictionary is not in the model.
                #Django, by design, will throw an exception
                #this prevents that
                kwargs.pop(key)

    return super(PortalModel, self_).__init__(*args, **kwargs)

  class Meta:
    abstract = True

继承类

class TestIP(PortalModel):

     address = models.CharField(max_length=128, verbose_name='VIP')

   class Meta:
       abstract = False
       verbose_name = 'testIP'
      verbose_name_plural = "testips"

试图在verbose_name_plural获取错误中调用views.py "AttributeError: class Meta没有属性'verbose_name_plural'“

Views.py

kwargs[TestIP.Meta.verbose_name_plural.lower().replace(' ', '')] = table

它在Django1.3中运行良好，请帮助解决这个问题。

提前感谢

我想出了答案

在Django1.5中，我们应该访问像'TestIP._meta.verbose_name_plural‘这样的元类

我变了

kwargs[TestIP.Meta.verbose_name_plural.lower().replace(' ', '')] = table

至

kwargs[TestIP._meta.verbose_name_plural.lower().replace(' ', '')] = table

它在django1.5中运行良好。
