Rubyコーディング規約 ❏Ruby❏

Last updated at Posted at 2019-11-24

#コーディング規約
ルールではなくマナー
僕が気をつけているポイントを紹介するよ!

#インデントは2つ

if num > 0
●●if num < 100
●●●●puts "100より小さい正の数"
●●end
end

#クラス内の各構成要素の区切りに空行を入れる
ただし、最初と最後は空けない。

tweets_controller.rb
class TweetsController < ApplicationController   #最初は空けない
  before_action :move_to_index, except: :index
#---ここ---
  def index
    @tweets = Tweet.all
  end
#---ここ---
  def new
    @tweet = Tweet.new
  end
#---ここ---
  def create
    Tweet.create(tweet_params)
  end
#---ここ---
  private
    def tweet_params
      params.require(:tweet).permit(:text, :image)
    end
#---ここ---
    def move_to_index
      redirect_to root_path unless user_signed_in?
    end
end   #最後も空けない

#if文のthen
while文のdoは省略する

if num < 100
  puts "100より小さい"
end

while num < 100
  puts num
  num += 1
end

#文字列リテラルはダブルクォーテーション

puts "ダブル!!"

もちろん例外もあるよ!

#三項演算子は簡単な条件の時のみ

puts score > 60 ? "合格":"不合格"

少しでも複雑ならif文!

#変数・メソッド名は小文字&スネークケース

#変数
num = 15
add_color = "yellow"

#メソッド
def index
end

def add_something
end

2単語繋げる場合は_を使う!
