Rails 콘솔에서 멋진 포맷을 얻는 방법

Rails 콘솔에서 멋진 포맷을 얻는 방법

---

다음과 같이 멋지게 보이기를 원합니다.

>> 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">]

작동하지 않습니다.

>> 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\">]"

그리고 이것도 마찬가지입니다.

>> 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"

이 y방법은 꽤 YAML 출력을 얻는 편리한 방법입니다.

y ProductColor.all

당신이 있다고 가정 script/console

jordanpg가 언급 했듯이이 답변은 구식입니다. Rails 3.2+의 경우 y메소드가 작동 하기 전에 다음 코드를 실행해야합니다 .

YAML::ENGINE.yamler = 'syck'

에서 루비 문서

예전의 루비 버전에서는 <= 1.9, Syck는 여전히 제공되지만 Ruby 2.0.0 릴리스에서는 완전히 제거되었습니다.

rails 4 / ruby ​​2의 경우 바로 사용할 수 있습니다

puts object.to_yaml

---

당신은 hirb 시도해야합니다 . 루비 콘솔에서 객체를 예쁜 형식으로 만들기 위해 만든 보석입니다. 스크립트 / 콘솔 세션은 다음과 같습니다.

>> 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

hirb에 대한 자세한 내용은 홈페이지를 참조하십시오 .

들여 쓰기를 원한다면 멋진 인쇄 도 좋습니다. 다음과 같은 것 :

$ 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
    }
]

기본적으로 irb / rails / pry 콘솔과 통합하려면 ~/.irbrc또는 ~/.pryrc파일에 추가 하십시오.

require "awesome_print"
AwesomePrint.irb! # just in .irbrc
AwesomePrint.pry! # just in .pryrc

---

또한 다음을 사용할 수 있습니다.

j ProductColor.all.inspect

Yaml 대신 Json 형식으로 출력

---

>> puts ProductColor.all.to_yaml

간단하게 잘 작동합니다!

---

안녕하세요, 스크립트 / 콘솔에서 시도해 볼 수도 있습니다.

>> y ProductColor.all

당신을 위해 작동하지 않습니다.

이 시도:

>> require 'yaml'

>> YAML::ENGINE.yamler = 'syck'

그때

>> y ProductColor.all

---

나는 그것을 작동시키는 데 문제가 있었으므로 awesome_print에 2 센트를 추가 할 것입니다 .Gemfile에 이것을 추가하십시오. :development

gem 'awesome_print', require: 'ap'

그런 다음

rails console

넌 할 수있어

> ap Model.all그게 다야. 그러나 당신은 또한 추가 할 수 있습니다

require "awesome_print"
AwesomePrint.irb!

~ / .irbrc에 콘솔을 열 때마다 awesome_print가 필요하며 간단하게 할 수 있습니다.

Model.all without the need of typing ap

---

Use irbtools gem.

It will automatically format the the console output plus you'll get tons of great features.

---

You might want to define ProductColor's inspect method to return something that you find nice. For example:

def inspect
  "<#{id} - #{name} (#{internal_name})>"
end

After which the result of ProductColor.all will display as something like [<1 - White (White)>, ...]. Of course you should adjust the inspect method to your needs, so that it displays all the information you need in a style that you like.

Edit: also if the issue was the lack of line breaks in the output, you might try

require 'pp'
pp ProductColor.all

which should insert linebreaks where appropriate

---

To add to Alter Lago's suggestion for using AwesomePrint, If you can't/shouldn't/don't want to add the awesome_print gem to your project's Gemfile, do this:

gem install awesome_print

Edit ~/.irb.rc and add this:

$LOAD_PATH << '/Users/your-user/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/gems/1.9.1/gems/awesome_print-1.1.0/lib'

require 'awesome_print'

(Making sure the path and version are correct, of course)

---

You may also try the following for a group of objects

Object.all.map(&:attributes).to_yaml

This will give you much nicer output, like

---
id: 1
type: College
name: University of Texas
---
id: 2
type: College
name: University of California

Calling to_yaml on attributes rather than the object itself saves you from viewing the full contents of the object in the output

Or puts Object.last.attributes.to_yaml for a single object

Shorthand is also available: y Object.last.attributes

---

I think this solution is the most accurate one. You should try this:

puts JSON.pretty_generate Entry.all.map(&:attributes)

This will give you a super nice output compare to YAML format:

[
  {
    "id": 44,
    "team_id": null,
    "member_id": 1000000,
    "match_id": 1,
    "created_at": "2019-04-09 15:53:14 +0900",
    "updated_at": "2019-04-09 15:53:14 +0900"
  },
  {
    "id": 45,
    "team_id": null,
    "member_id": 1000001,
    "match_id": 1,
    "created_at": "2019-04-09 15:53:36 +0900",
    "updated_at": "2019-04-09 15:53:36 +0900"
  },
  {
    "id": 46,
    "team_id": null,
    "member_id": 1000003,
    "match_id": 1,
    "created_at": "2019-04-09 15:56:40 +0900",
    "updated_at": "2019-04-09 15:56:40 +0900"
  },
  {
    "id": 47,
    "team_id": null,
    "member_id": 1000004,
    "match_id": 1,
    "created_at": "2019-04-09 15:56:48 +0900",
    "updated_at": "2019-04-09 15:56:48 +0900"
  }
]
