4.如何在Django-admin添加数据库视图

你有这样创建的数据库视图：

create view entities_entity as
    select id, name from entities_hero
    union
    select 10000+id as id, name from entities_villain

它具有Hero和Villain所有的名称， Villain的id设置为10000+id,因为我们不打算横过10000名Heros

sqlite> select * from entities_entity;
1|Krishna
2|Vishnu
3|Achilles
4|Thor
5|Zeus
6|Athena
7|Apollo
10001|Ravana
10002|Fenrir

然后添加一个managed=False模型:

class AllEntity(models.Model):
    name = models.CharField(max_length=100)
    class Meta:
        managed = False
        db_table = "entities_entity"

并添加到admin:

@admin.register(AllEntity)
class AllEntiryAdmin(admin.ModelAdmin):
    list_display = ("id", "name")

你的admin看起来像这样：
