Add the resource to your browser scope in web/router.ex:

    resources "/posts", PostController

Remember to update your repository by running migrations:

    $ mix ecto.migrate

してあげた

ログにあるようにルーティング追加してあげた resources "/posts", PostController

一つだけ注意しときたいなと思ったのが、タイムスタンプ。 Railsでは生成されるフィールドがcreated_at, updated_atだったが、 Phoenixではinserted_at, updated_atだった。

とりあえず新規作成、編集、削除、表示、戻るボタンなどを試したのでclose!
