Heroku 不在 Rails 4 应用程序中显示图像或字体

Question

我已经尝试severalguides 让图像和字体出现在 Heroku 上，但似乎没有任何效果。预编译然后推送到 Heroku 和 changing images are referenced 似乎也不起作用。任何帮助将非常感激。 Full source code here.

例如 stylesheets/themes/default/style.css

.iconset {
  background-image: image-url("icon/top-tray.png")  no-repeat;
  background-image: url(image-path('icon/top-tray.png')) no-repeat;
  background-image: asset_path('icon/top-tray.png') no-repeat;
  background: url(<%= asset_path 'icon/top-tray.png' %>) no-repeat;
}

呈现为

.iconset {
  background-image: image-url("icon/top-tray.png")  no-repeat;
  background-image: url(image-path('icon/top-tray.png')) no-repeat;
  background-image: asset_path('icon/top-tray.png') no-repeat;
  background: url(<%= asset_path 'icon/top-tray.png' %>) no-repeat;
}

config/environments/production.rb

  config.serve_static_assets = false
  config.assets.compile = false

config/application.rb

config.assets.paths << Rails.root.join('app', 'assets', 'fonts', 'plugins', 'scss')

config.assets.precompile += %w( .svg .eot .woff .ttf .png .jpg .gif)

Answer 1

解决方法是将config/environments/production.rb file中的config.assets.compile = false改为config.assets.compile = true。
