django admin排序外键字段列表 [英] django admin sort foreign key field list

问题描述

在django管理视图中是否有一个选项来排序外键字段？即我有一个外键为学校模式，它显示为一个下拉列表，按照pk排序 - 我希望按字母顺序排序。

Is there an option in the django admin view for ordering of foreign key fields? i.e. I have a foreign key to a "School" model, which shows as a dropdown, sorted on pk-- I would like it to be sorted alphabetically.

推荐答案

当然可以...

• ModelAdmin具体通过formfield_for_foreignkey进行排序


• 通过Manager设置默认全局排序


• 通过模型元类设置默认排序


• 表单具体订购传递给您的ModelAdmi n

• ModelAdmin specific ordering via formfield_for_foreignkey
• Set default global ordering via a Manager
• Set default ordering via model meta class
• Form specific ordering then passed to your ModelAdmin

ModelAdmin具体方法（其他方法在我的回答中链接到上面）

ModelAdmin specific method: (the other methods are in my answer in the post linked to above)

class MyModelAdmin(admin.ModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
        if db_field.name == "school":
            kwargs["queryset"] = School.objects.order_by('name')
        return super(MyModelAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

其他3个非管理员特定方法的示例我的帖子链接在上面。
