开发中的ERB未处理Rails Asset Path中的CSS [英] CSS in Rails Asset Path not processed by ERB in development

问题描述

我在/app/assets/stylesheets/styles.css.erb中有一个具有以下内容的Rails应用程序:

I have a Rails app with the following in /app/assets/stylesheets/styles.css.erb:

...
#nestedbg {
    background-position: left top;
    background-image: url(<%= asset_path 'siteheader2.png' %>);
    background-repeat: repeat-x;
    background-attachment: fixed;
}
...

当我运行rake assets:precompile然后运行rails s -e production时，一切都会按预期进行.但是，当我删除预编译的资产并在开发中运行rails s时，CSS文件就会如上图所示出现，而不是被正确替换了.

When I run rake assets:precompile and then run rails s -e production, everything works as expected. However, when I remove the precompiled assets and run rails s in development, the CSS file comes up as shown above instead of being properly substituted.

我尝试将config.assets.compile = true放入/config/environments/development.rb，但这没有帮助.

I tried putting config.assets.compile = true in /config/environments/development.rb and that did not help.

有什么想法吗? 谢谢.

Any ideas? Thanks.

推荐答案

我正在使用Rails 3.1.1，当我将应用程序切换为使用Rails 3.1.3时，问题就消失了.我切换回3.1.1，以查看问题是否再次出现.

I was using Rails 3.1.1 and when I switched the app to use Rails 3.1.3, the problem went away. I switched back to 3.1.1 to see if the issue came back and it did not.

我猜这是其中一个gem的问题，对3.1.3的更新带来了其他gem更新.

I'm guessing that it was a problem with one of the gems and the update to 3.1.3 brought other gem updates with it.
