Rails6.1では、notyをCDNで読み込ませる際に「app/views/layouts/application.html.erb」ファイルのheadタグに直接記述していました。
Rails7.1ではimportmapが標準となり、そこからCDNを読み込ませることができます。
しかし、notyのバージョンが古く、importmapで対応していないためScriptだけScriptタグで直接読み込ませ、CSSを新たに作成して動かします。


まず、notyのCSSファイルを作成します。
「app/assets/stylesheets」フォルダに「_noty.scss」という名前のファイルを新規作成します。
作成した「_noty.scss」ファイルを以下のように編集します。


新規作成 【app/assets/stylesheets/_noty.scss】

#noty_layout__bottom,#noty_layout__bottomCenter,#noty_layout__bottomLeft,#noty_layout__bottomRight,#noty_layout__center,#noty_layout__centerLeft,#noty_layout__centerRight,#noty_layout__top,#noty_layout__topCenter,#noty_layout__topLeft,#noty_layout__topRight,.noty_layout_mixin{position:fixed;margin:0;padding:0;z-index:9999999;-webkit-transform:translateZ(0)
