Django 静的ファイル (static) 関係の設定まとめ

The reason that STATICFILES_DIRS wants a filesystem path is that it needs to know where the files live in the operating system (so things like manage.py collectstatic are possible). The STATIC_URL setting is for webserver paths, and that's what it uses to show to the user in the admin or the {% static %} tag or whatever. STATICFILES_DIRS is server-side only and never shows up in any rendered templates or anything.

※まとまってない

Djangoを本番環境にデプロイするとき、静的ファイル関係の設定でいろいろはまったので、まとめる。 基本的に以下の5つあるようだが、上から3つだけ使用していたので、それらに関してまとめる。 ちなみに以下のそれぞれの定数はsetting.pyで設定する。

STATIC_ROOT
STATIC_URL
STATICFILES_DIRS (Prefixes (optional))
STATICFILES_STORAGE
STATICFILES_FINDERS
