Ruby on rails 产品中的rails映像路径问题，没有自定义域，没有指纹，路径错误

这是一个rails 3.2.13应用程序

我很困惑这里的问题是什么。非常感谢您的帮助。 我在这个位置有我的图像：

app/assets/images/icons/apple-touch-icon-precomposed.png

public/assets/icons/apple-touch-icon-precomposed-5796a048f16a314924adbb237adf88d6.png

这在layout.html.erb中：

<link rel="apple-touch-icon-precomposed" href="<%= image_path("icons/apple-touch-icon-precomposed.png") %>" />

这是我的

config/environments/production.rb

：

Aliencom::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # Code is not reloaded between requests
  config.cache_classes = true

  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)

  Paperclip::Attachment.default_options.update({

根据我在生产中的经验，从公共目录加载的文件没有经过编译。 尝试将图像与文件名完整的相应文件夹一起放入公共目录

---

因此，对于

/icons/apple-touch-icon-precomposed.png

将其放入

/public/assets/icons/apple-touch-icon-precomposed.png

尝试放入未编译的图像。

您是否正在运行

RAILS\u ENV=production-rake-assets:precompile

？它现在指向产品中的链接是什么？右键单击并查看url。是的，需要在prod模式下预编译资产才能找到它们。不过，根据您发布的链接，我认为它们是正确的。@Slicedpan我发布了capistrano输出，我认为这是正确的行。@Isafie生产路径输出包含在上面。@LessQuesar尝试转换erb/haml（无论您使用什么）是的，这确实有效。主要令人沮丧的是，我不知道如何为指纹/自定义域等正确使用图像路径。CSS和JS链接良好。这是一个常见问题。我有一个应用程序与另一个应用程序使用相同的代码，其中一个将使用编译后的图像，而另一个则对原始图像大喊大叫。我还没有发现原因。有点像魔术，我让它起作用了。我黑了一堆像这里描述的设置：还有更多，不确定是什么造成了不同。但我想我要结束这一次了。
