未预编译file.png [英] file.png isn't precompiled

问题描述

我以为我已经确定了资产流水线，但现在没有了.

I thought I had the assets pipeline figured out, but not any more.

我有一个名为clients.css.scss的样式表

I have a stylesheet named clients.css.scss

.client
{

  .list_view
  {
    width: 650px;
    height: 500px;
    overflow: auto;

    table
    {
      width: 650px;
      border: solid 2px #999999;
      border-collapse: collapse;

      thead tr
      {
        background: image-url('list-view-header.png') repeat-x;
      }

      thead tr:first-child
      {
        background-image: none;
      }
    }
  }
}

每次我尝试在生产环境中对其进行预编译时，都会不断出现未预编译file.png"错误.

Every time I try to precompile it in production I keep getting a "file.png isn't precompiled" error.

bundle exec  rake assets:precompile RAILS_ENV=production --trace
/usr/local/rvm/gems/ruby-1.9.2-p290@pm/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_

  (in /var/rails/pm.onlinetherapy.com/app/assets/stylesheets/clients.css.scss.erb)

Tasks: TOP => assets:precompile
(See full trace by running task with --trace)

该图像文件位于app/assets/images目录中，我可以在public/assets目录中看到它的扩展指纹名称.

The image file is in the app/assets/images directory and I can see it in the public/assets directory with the extended finger print name.

任何想法都会有所帮助.

Any ideas would be helpful.

推荐答案

我相信您想要的是这样的:

I believe that what you want is this:

thead tr
  {
    background: image-url('/assets/list-view-header.png') repeat-x;
  }

或者您也可以将clients.css.scss更改为clients.css.scss.erb，然后执行以下操作:

Or you can change your clients.css.scss to clients.css.scss.erb and do this:

thead tr
  {
    background: image-url(<%= asset_path "list-view-header.png" %>) repeat-x;
  }
