今回は「アプリケーション」の作成を行います。

djangoもバックエンドを取り扱うものですので、
JSのexpressのように

・モデル
・ビュー
・コントローラー

のような機能を持っています。

アプリケーションの作成は、
上記の3点をモデルごとにフォルダ分けするようなイメージです。

ユーザーの管理を行うアプリケーション
python manage.py startapp accounts

ポストの管理を行うアプリケーション
python manage.py startapp posts

アプリケーションの作成ができましたら、
「myapp」直下の「settings.py」の30行目付近、
「INSTALLED_APPS」のリストに作成したアプリを追加します。

myapp/settings.py
