如何在Rails控制台中获得良好的格式
如何在Rails控制台中获得良好的格式
提问于 2009-08-03 20:43:19
我想让这样的东西看起来更漂亮：
>> ProductColor.all
=> [#<ProductColor id: 1, name: "White", internal_name: "White", created_at: "2009-06-10 04:02:44", updated_at: "2009-06-10 04:02:44">, #<ProductColor id: 2, name: "Ivory", internal_name: "Ivory", created_at: "2009-06-10 04:02:44", updated_at: "2009-06-10 04:02:44">, #<ProductColor id: 3, name: "Blue", internal_name: "Light Blue", created_at: "2009-06-10 04:02:44", updated_at: "2009-06-10 04:02:44">, #<ProductColor id: 4, name: "Green", internal_name: "Green", created_at: "2009-06-10 04:02:44", updated_at: "2009-06-10 04:02:44">]这不起作用：
>> ProductColor.all.inspect
=> "[#<ProductColor id: 1, name: \"White\", internal_name: \"White\", created_at: \"2009-06-10 04:02:44\", updated_at: \"2009-06-10 04:02:44\">, #<ProductColor id: 2, name: \"Ivory\", internal_name: \"Ivory\", created_at: \"2009-06-10 04:02:44\", updated_at: \"2009-06-10 04:02:44\">, #<ProductColor id: 3, name: \"Blue\", internal_name: \"Light Blue\", created_at: \"2009-06-10 04:02:44\", updated_at: \"2009-06-10 04:02:44\">, #<ProductColor id: 4, name: \"Green\", internal_name: \"Green\", created_at: \"2009-06-10 04:02:44\", updated_at: \"2009-06-10 04:02:44\">]"这一点也不是：
>> ProductColor.all.to_yaml
=> "--- \n- !ruby/object:ProductColor \n attributes: \n name: White\n created_at: 2009-06-10 04:02:44\n updated_at: 2009-06-10 04:02:44\n id: \"1\"\n internal_name: White\n attributes_cache: {}\n\n- !ruby/object:ProductColor \n attributes: \n name: Ivory\n created_at: 2009-06-10 04:02:44\n updated_at: 2009-06-10 04:02:44\n id: \"2\"\n internal_name: Ivory\n attributes_cache: {}\n\n- !ruby/object:ProductColor \n attributes: \n name: Blue\n created_at: 2009-06-10 04:02:44\n updated_at: 2009-06-10 04:02:44\n id: \"3\"\n internal_name: Light Blue\n attributes_cache: {}\n\n- !ruby/object:ProductColor \n attributes: \n name: Green\n created_at: 2009-06-10 04:02:44\n updated_at: 2009-06-10 04:02:44\n id: \"4\"\n internal_name: Green\n attributes_cache: {}\n\n"有什么想法？

你应该试试hirb。它是用来在ruby控制台中格式化对象的一块宝石。您的脚本/控制台会话将如下所示：
>> require 'hirb'
=> true
>> Hirb.enable
=> true
>> ProductColor.first
+----+-------+---------------+---------------------+---------------------+
| id | name | internal_name | created_at | updated_at |
+----+-------+---------------+---------------------+---------------------+
| 1 | White | White | 2009-06-10 04:02:44 | 2009-06-10 04:02:44 |
+----+-------+---------------+---------------------+---------------------+
1 row in set
=> true你可以在它的homepage上了解更多关于hirb的信息。

如果你想缩进一个对象，Awesome print也不错。类似于：
$ rails console
rails> require "awesome_print"
rails> ap Account.all(:limit => 2)
[
[0] #<Account:0x1033220b8> {
:id => 1,
:user_id => 5,
:assigned_to => 7,
:name => "Hayes-DuBuque",
:access => "Public",
:website => "http://www.hayesdubuque.com",
:toll_free_phone => "1-800-932-6571",
:phone => "(111)549-5002",
:fax => "(349)415-2266",
:deleted_at => nil,
:created_at => Sat, 06 Mar 2010 09:46:10 UTC +00:00,
:updated_at => Sat, 06 Mar 2010 16:33:10 UTC +00:00,
:email => "info@hayesdubuque.com",
:background_info => nil
},
[1] #<Account:0x103321ff0> {
:id => 2,
:user_id => 4,
:assigned_to => 4,
:name => "Ziemann-Streich",
:access => "Public",
:website => "http://www.ziemannstreich.com",
:toll_free_phone => "1-800-871-0619",
:phone => "(042)056-1534",
:fax => "(106)017-8792",
:deleted_at => nil,
:created_at => Tue, 09 Feb 2010 13:32:10 UTC +00:00,
:updated_at => Tue, 09 Feb 2010 20:05:01 UTC +00:00,
:email => "info@ziemannstreich.com",
:background_info => nil
}
]要在默认情况下将其与irb/rails/pry控制台集成，请添加到您的~/.irbrc或~/.pryrc文件：
require "awesome_print"
AwesomePrint.irb! # just in .irbrc
AwesomePrint.pry! # just in .pryrcStack Overflow用户
