过滤器的管理网站，如何工程FilterSpec，RelatedFilterSpec，ChoicesFilterSpec即？

Question

昨天，当我在Django中为我的管理站点编写特殊的过滤器时，我遇到了这个问题。

我有3个型号：

​

class ShopInfo(models.Model):
    name = models.CharField(max_length=200)


class Keyword(models.Model):
    keyword1 = models.CharField(max_length=4096,  blank=True)
    product = models.ManyToManyField(Products)


class Products(models.Model):
    shop = models.ForeignKey(ShopInfo)




In Admin site, on the Keyword edit page, I want create a filter for Keywords by shop.
In other words, I want to see full list of shops in filter list on the right of page, when you click on that we will choose the Keywords belonged this shop.

为此，您不需要任何自定义的FilterSpecs。您可以在ModelAdmin的list_filter属性中使用django的连接语法。例如：

class KeywordAdmin(admin.ModelAdmin):
    list_filter = ['product__shop']
