Question

作为一名编程初学者，我第一次在Heroku上部署了Rails应用程序。我收到500错误，但找不到源。如果您可以帮助我在日志中找到它，那就太好了。请让我知道我需要共享进行调试的其他信息。

时间不多，要检查的东西很多链接到日志详细信息：https://pastebin.com/xPAkGWA8

Answer 1

这是错误：ActionView::Template::Error (Must supply cloud_name in tag or in configuration)

似乎您没有配置CLOUDINARY_URL，如此处所述：https://cloudinary.com/documentation/rails_integration#configuration

这是摘录，您应该寻找“ FATAL”标识符。

Answer 3

我认为您忘记在Rails应用程序中配置Heroku应用程序。您可以使用“ Heroku config” 对其进行配置。或者可以通过@beauraF。（https://devcenter.heroku.com/articles/config-vars）提供的链接。
