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

问题描述

django 管理视图中是否有用于排序外键字段的选项?即我有一个学校"模型的外键，它显示为一个下拉列表，按 pk 排序——我希望它按字母顺序排序.

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 - 你可以...

Sure - you can...

• ModelAdmin 特定排序通过 formfield_for_foreignkey
• 通过管理器设置默认全局排序
• 通过模型元类设置默认排序李>
• 表单特定排序然后传递给您的 ModelAdmin

ModelAdmin 特定方法:(其他方法在我上面链接的帖子中的回答中)

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)
