Django:list_filter 和外键字段 [英] Django: list_filter and foreign key fields

问题描述

Django 不支持从 list_display 或 list_filter(例如 foo__bar)获取外键值.我知道您可以创建一个模块方法作为 list_display 的解决方法，但是我将如何为 list_filter 做同样的事情?谢谢.

Django doesn't support getting foreign key values from list_display or list_filter (e.g foo__bar). I know you can create a module method as a workaround for list_display, but how would I go about to do the same for list_filter? Thanks.

推荐答案

Django 支持带有外键字段的 list_filter

Django supports list_filter with foreign key fields

# models.py:
class Foo(models.Model):
    name = models.CharField(max_length=255)

    def __unicode__(self):
        return self.name

class Bar(models.Model):
    name = models.CharField(max_length=255)
    foo = models.ForeignKey(Foo)

# admin.py:
class BarAdmin(admin.ModelAdmin):
    list_filter = ('foo__name')

来自文档:list_filter 中的字段名称也可以使用 __ 查找跨越关系

From documentation: Field names in list_filter can also span relations using the __ lookup
