Ruby 在脚本中插入 ENV[api_key]

Question

在 application.yml 我有 api_key: 1234567890

如果我这样做（直接插入 api 键 'appid'）它会工作（小部件显示和填充）：

<script>
  window.myWidgetParam ? window.myWidgetParam : window.myWidgetParam = [];  window.myWidgetParam.push({id: 15,cityid: '2643743',appid: '1234567890' %>,units: 'metric',containerid: 'openweathermap-widget-15',  });  (function() {var script = document.createElement('script');script.async = true;script.charset = "utf-8";script.src = "//openweathermap.org/themes/openweathermap/assets/vendor/owm/js/weather-widget-generator.js";var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(script, s);  })();
</script>

但是如果我这样做（插入 <%= ENV["api_key"] %>）它不会（由于缺少 api 键周围的引号，小部件未显示）：

<script>
  window.myWidgetParam ? window.myWidgetParam : window.myWidgetParam = [];  window.myWidgetParam.push({id: 15,cityid: '2643743',appid: <%= ENV["api_key"] %>,units: 'metric',containerid: 'openweathermap-widget-15',  });  (function() {var script = document.createElement('script');script.async = true;script.charset = "utf-8";script.src = "//openweathermap.org/themes/openweathermap/assets/vendor/owm/js/weather-widget-generator.js";var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(script, s);  })();
</script>

我错过了什么？

Answer 1

appid: '<%= ENV["api_key"] %>'怎么样？

Answer 2

我会做：

<%== ENV['api_key'].to_json %>
