かっこよくredirectかつreturn in rails

Posted at

Railsのコントローラーで、redirectして更にその後の処理をしたくないときはかなりあると思います。
そんなとき僕は今まで

users_controller.rb
def show
  @user = User.find params[:id]
  if @user.nil?
    redirect_to :root
    return
  end
end

と書いていて、ただのチェックの処理に4行も使っているのがすごく不満だったのですが

users_controller.rb
def show
  @user = User.find params[:id]
  return redirect_to :root if @user.nil?
end

このようにreturn redirect_to ... if ...と書けば一行で、更にかっこ良く書けることに今更ながら気づきました。
