Ruby on rails 3 在rails控制台中创建数据库表的图形视图

我需要在rails控制台中创建表的图形视图。以国家为例 它以图形形式向我显示了一个表格！[在此处输入图像描述][1]

---

我不知道该用那颗宝石。我是新手

您可以使用“hirb”gem在rails控制台中获取图形视图

gem install hirb

rails c

开放式轨道控制台

gem install hirb

rails c

那就试试这个

2.1.2 :001 > require 'hirb'
 => false 
2.1.2 :002 > Hirb.enable
 => true 
2.1.2 :003 > Advertiser.all
  Advertiser Load (3.1ms)  SELECT "advertisers".* FROM "advertisers"  WHERE "advertisers"."deleted_at" IS NULL
