Question

这是rails 3.2.13 app。

我很困惑这里的问题是什么。任何帮助深表感谢。我在这个位置有我的形象：

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

这是在layout.html.erb中：

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

在开发中它正确链接：

<link ... href="/assets/icons/apple-touch-icon-precomposed.png" />

生产中

it does not link correctly:
<link ... href="/icons/apple-touch-icon-precomposed.png" />
what i am expecting:    
<link ... href="http://asset.domain.com/assets/icons/apple-touch-icon-precomposed-5796a048f16a314924adbb237adf88d6.png" />

当我浏览生产服务器时，我在正确的位置看到了带有缩略图的图像：

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

这是我的config/environments/production.rb：

Answer 1

在生产中，我的经验是从PUBLIC目录加载的文件未编译。尝试将图像放在PUBLIC目录中，并使用文件名完整的相应文件夹。

因此，/icons/apple-touch-icon-precomposed.png将其放入/public/assets/icons/apple-touch-icon-precomposed.png尝试放入非编译图像。

rails prod中的image_path问题，没有自定义域，没有指纹，路径错误
