やっと出て来たのが rabl-rails 版ｗ

[speee-nakajima]

• rabl-railsをやってみる
• せっかく出てきたからやってみるか...

mkdir -p ossws/gon

• gon rabl-rails いれる
• rails ありきだからGemfileに追記する形で書いてあるのか...

gem 'gon'
gem 'rabl-rails'

bundle

入った

これ Rabl-Rails みないとあかんやつや

[speee-nakajima]

• 普通の rails で gon を動かす
• rabl読むの辛いから普通のrailsで動かすために上に戻ってその通り書いてみる
• 最初から普通のrailsで動かすための一通りの手順を入れてほしい(rails入っている前提でなく...)
• この辺

[speee-nakajima]

• rails アプリケーションを作る
• 確認用のcontrollerとviewを作る

vi app/views/application.html.erb

下記LINEを追加
一度使ったことあるからなんとなく入れることもわかるけど一発でわかるのだろうか？
でも、このまままるっとコピっても動くからよし？

<%= Gon::Base.render_data %>

controllerを作る

bundle exec rails g controller test

gon.your_int = @your_int
gon.your_other_int = 345 + gon.your_int
gon.your_array = @your_array
gon.your_array << gon.your_int
gon.your_hash = @your_hash

gon.all_variables # > {:your_int => 123, :your_other_int => 468, :your_array => [1, 2, 123], :your_hash => {'a' => 1, 'b' => 2}}
gon.your_array # > [1, 2, 123]

gon.clear # gon.all_variables now is {}

[speee-nakajima]

• rails アプリケーション上でgonを動かす
• routes と view を作るの忘れてた

config/route.rb

...
get '/test' => 'test#index'

test/index.erb

test

[speee-nakajima]

• rails アプリケーション動いた
• そのままコピペすると gon.clear が入っているので何も出ないでちょっと困りそう

[speee-nakajima]

• rails アプリ動かしながら
• tutorial ぐらいあるとパっと動きが確認できるので助かる

[speee-nakajima]

• gon で rspec を動かしてみよう

• rspec 動かす
• contributing 書いてほしい

[speee-nakajima]

• rspecを動かす
• gem の spec はこう動かすのか...

bundle exec rake spec

[speee-nakajima]

• issueの内容を考える(思案中)
  *

初めに instration をつけてほしい
その中で rails と gon が使える簡単な example を入れてほしい
rails new から いれたいなーと思ったけど

Very good and detailed example and reasons to use is considered in railscast by Ryan Bates

があったっぽいできれば readme 上で完結したい

contributing を作って欲しい

[speee-nakajima]

• issueの内容を考える(思案中)

# or new syntax
gon.push({
  :user_id => 1,
  :user_role => "admin"
})

を

user_id: 1

とかに書き直す

[speee-nakajima]

• issueを考える
• そのまま書くと

gon.clear

が入ってて動きが不安

[speee-nakajima]

• issueの内容を考える

readme を読んでさっと確認したいので rails と gon を含んだものを example に載せてほしい

Usage のところで gon.clear が入っているがそのまま下の example と一緒に動かすと何も表示されずに困るのでコメントとかにしておいてほしい

[speee-nakajima]

• issue
• Usage のコードをそのまま貼り付けて動かすと何も値がでないので動くものをおいておいてほしい
  gon.clear が問題だと思うのでコメントアウトしてもらえるとさっと動くので助かる

[speee-nakajima]

• issueを考える

開発者向け

rails の環境を構築して gon をドキュメント通りに導入して Usage のところを一通りコピーして実行すると alert で何かが表示されるのが期待されるが何も変数が表示されずに困った。

理由は controller のコードに gon.clear が最後に書かれているので起こった問題だった。

なので、 gon.clear は便利な機能だと思うがコメントアウトなどで書いておいてもらえると嬉しい。

• 英語にしてみる

sample code do not run as expected

i build rails app with gon.
i installed gon using your documentation.
and, i copied the code from Usage.
i expected to display something variables in alert box.
but, display nothing.

show my steps below:

mkdir test_app
cd test_app
vi Gemfile

Gemfile

source 'https://rubygems.org'
gem 'rails'

bundle

...

bundle exec rails new .

...

• add gon into Gemfile

i tried to commentout gon.clear line, this issue is solved!

app/controllers/test_controller.rb

#gon.clear # gon.all_variables now is {}

so, gon.clear is useful features!
but, i want to commentout gon.clear line in sample code.

サンプルコードをコピーして実行したが動かなかった

rails の環境を構築して gon をドキュメント通りに導入して Usageのところを一通りコピーして実行すると alert で何かが表示されるのが期待されるが何も変数が表示されずに困った。

試しに controller の gon.clear をコメントアウトしたら表示されるようになったので、サンプルコード上では gon.clear をコメントアウトにしてほしい。

version には関係ないと思うが、記載します

rails: 4.2.6
ruby: 2.2.3

# gon.clear

下記に作成手順を示します。

mkdir test_app
cd test_app
vi Gemfile

Gemfile

source 'https://rubygems.org'
gem 'rails'

bundle

...

bundle exec rails new .

• Gemfileにgonを追加

Gemfile

gem 'gon'         # add

bundle

...

sample code do not run as expected

Hi.

I build rails app with gon.
I installed gon using your documentation.
and, I copied the code from Usage.
I expected to display something variables in alert box.
but, display nothing.

I tried to commentout gon.clear line, this issue is solved!
so, gon.clear is useful features!
but, I want to commentout gon.clear line in sample code like this.

@your_int = 123
@your_array = [1,2]
@your_hash = {'a' => 1, 'b' => 2}
gon.your_int = @your_int
gon.your_other_int = 345 + gon.your_int
gon.your_array = @your_array
gon.your_array << gon.your_int
gon.your_hash = @your_hash

gon.all_variables # > {:your_int => 123, :your_other_int => 468, :your_array => [1, 2, 123], :your_hash => {'a' => 1, 'b' => 2}}
gon.your_array # > [1, 2, 123]

#gon.clear # gon.all_variables now is {}

show ruby and rails versions.

rails: 4.2.6
ruby: 2.2.3

appendix) show my steps.

mkdir test_app
cd test_app
vi Gemfile

Gemfile

source 'https://rubygems.org'
gem 'rails'

bundle
...
bundle exec rails new .
...

Gemfile

gem 'gon'         # add

bundle
...

application.html.erb

...
<%= Gon::Base.render_data %>
...

bundle exec rails g controller test
...

get '/test' => 'test#index'

def index
  @your_int = 123
  @your_array = [1,2]
  @your_hash = {'a' => 1, 'b' => 2}
  gon.your_int = @your_int
  gon.your_other_int = 345 + gon.your_int
  gon.your_array = @your_array
  gon.your_array << gon.your_int
  gon.your_hash = @your_hash

  gon.all_variables # > {:your_int => 123, :your_other_int => 468, :your_array => [1, 2, 123], :your_hash => {'a' => 1, 'b' => 2}}
  gon.your_array # > [1, 2, 123]

  gon.clear # gon.all_variables now is {}
end

alert(gon.your_int)
alert(gon.your_other_int)
alert(gon.your_array)
alert(gon.your_hash)
