![Django Admin后台管理][Django Admin 8]

（5）关联对象

无法直接访问关联对象的属性或方法，可以在模型类中封装方法，访问关联对象的成员。

（a）例如：显示父级地区，如果没有父级就返回空

![Django Admin后台管理][Django Admin 9]

效果：

![Django Admin后台管理][Django Admin 10]

（6）分组显示：fields与fieldsets只能用一个

（7）关联对象

在一对多的关系中，可以在一端的编辑页面中编辑多端的对象，嵌入多端对象的方式包括表格、块两种。类型InlineModelAdmin：表示在模型的编辑页面嵌入关联模型的编辑。子类TabularInline：以表格的形式嵌入。子类StackedInline：以块的形式嵌入

（a）StackedInline，写入models.py的AreaInfo，在管理类写入Inlines = \[AreaStackedInline\] \#类名，extra = 2 表示额外添加两个空行

![Django Admin后台管理][Django Admin 13]
