Django中的自定义过滤器（1.3）Admin

Question

如何在Django Admin中添加一个过滤器，该过滤器应该在模型仪表板右侧显示的过滤器中给出过滤结果。

更清楚：

class County (models.Model): 
    status = models.CharField(max_length = 255, blank = True) 
    name = models.CharField(max_length = 255, blank = True) 


class County_info (models.Model): 
    county = models.ForeignKey(County) 
    city = models.CharField(max_length = 255, blank = True) 
    state = models.CharField(max_length = 255, blank = True) 
    ...... 
    ...... 

在我adim.py我必须表明该模型“County_info”的具有状态“生产”领域“县”的过滤器。

list_filter = ['county__name', ] # will Show all data in that table. I need onlt the data which has status= 'production' 

我该怎么做？

前几天我有同样的问题，我想出了它只能使用1.4：Admin filter documentation
