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)
......
......
在我的 adim.py 中,我必须为状态为“生产”的字段“县”显示模型“县信息”的过滤器。
list_filter = ['county__name', ] # will Show all data in that table. I need onlt the data which has status= 'production'
我怎样才能做到这一点 ?
