前提

本題

上のを参考に日本地図を描画する

ゆくゆくは変数を渡したいけど今回の目標は素の日本地図を描画すること

js ファイルを記事を参考にセットアップ。しかし描画されず

コンソールでは

Uncaught ReferenceError: google is not defined

読み込みエラー


読み込み位置が悪かった

= javascript_include_tag 'application'
script src="https://www.gstatic.com/charts/loader.js"  

ってなってたけど正しくは

script src="https://www.gstatic.com/charts/loader.js"  
= javascript_include_tag 'application'

地図をロードする前にマニフェストファイルを読み込もうとしていた
