我正在进行codecademy练习portfolio而我无法理解资产管道位:第14步,其中指示说:
将您的JavaScript代码保存到app / assets / javascripts /,然后将其包含在此处显示的页面(链接)。
我所做的是在该目录中创建app.js文件,并将我的javascript代码放在该文件中,以便在application.html.erb中进行图片幻灯片放映和jquery。我可以看到幻灯片放映,一切正常,当我使用heroku部署应用程序时,我无法看到幻灯片而不是所有图片。这是我到目前为止所做的链接:[Myapp] [3]
我是Rails的新手,所以如果有人能够澄清教学期望我做什么以及如何在heroku中看到幻灯片,我们将不胜感激。

GET https://unslider.com/unslider.min.js net::ERR_INSECURE_RESPONSE
Unslider.com不支持HTTPS。
Heroku应用程序在HTTPS上运行,因为您使用的是协议相对链接//unslider.com/unslider.min.js
,它还会尝试通过HTTPS加载脚本。
最简单的解决方案是下载脚本并将其放在/vendor/assets/javascripts
中。
如果您想使用sprockets将文件包含在application.js中,请参阅How do you instruct Sprockets to include files from /vendors/assets/components on Heroku?。
