チュートリアル4章

htmlで

<%= yield(:title) %> | Ruby on Rails Tutorial Sample App
.
.
.
#各viewのタイトル
<% provide(:title, "Home") %>

これがあったと思うが、もしtitleをいれてなかったら上手く表示されないので、タイトルなしでも対応できるように

app/helpers/application_helper.rb
 module ApplicationHelper

  # ページごとの完全なタイトルを返します。
  def full_title(page_title = '')
    base_title = "Ruby on Rails Tutorial Sample App"
    if page_title.empty?
      base_title
    else
      page_title + " | " + base_title
    end
  end
end
app/views/layouts/application.html.erb
<title><%= full_title(yield(:title)) %></title>
#ヘルパーを作ったのでタイトル部分をこれに変更する

4章はconsoleでrubyの勉強が主だったのでコーディング自体はほぼしてないので、git pushして、終わり。
