标签： css ruby-on-rails-4 asset-pipeline fingerprinting

我在rails 4中遇到资产管道问题。 我在testapp/public/assets/中有一个目录，其中包含所有哈希或指纹css和javascripts bootstrap.min-58853fb115aba672ce98597de33da61b.js OR animate-d81627498b7ff4acf1a1964da02db789.css但是在浏览器中我看到没有哈希的css和javascripts，如<link rel="stylesheet" media="all" href="/stylesheets/bootstrap.min.css">  我需要在我的public / assets /

中请求散列文件 我有登陆控制器和一种方法 视图/降落/ one.html.erb 

<%= render "shared/headmeta" %>
<%= render "shared/headcss"%>
<%= render "shared/headscript"%>
<%= render "shared/header"%>

<h1>Landing#one</h1>
<p>Find me in app/views/landing/new.html.erb</p>


<%= render "shared/footer"%>
<%= render "shared/jscript"%

＆GT;

css在landing.scss中显示

/* ...
 *= require animate
 *= require bootstrap.min
 *= require default
 *= require style
 *= require overwrite
*/

headcss partial是：

<!-- Bootstrap core CSS -->
        <%= stylesheet_link_tag "bootstrap.min",  media: "all", "data-turbolinks-track" => true  %>

    <!-- Overwrite bootstrap style -->

    <%= stylesheet_link_tag "overwrite", media: "all","data-turbolinks-track" => true  %>

    <!-- Animate css -->

    <%= stylesheet_link_tag "animate", media: "all","data-turbolinks-track" => true  %>

    <!-- Heading font -->

    <%= stylesheet_link_tag "stylesheet", media: "all","data-turbolinks-track" => true %>

    <!-- General font -->
        <%= stylesheet_link_tag "http://fonts.googleapis.com/css?family=Open+Sans", media: "all" ,"data-turbolinks-track" => true%>

2 个答案:

答案 0 :(得分：1)

您在一个页面/应用中包含9个样式表吗？为什么不使用清单将它们编译成一个？

我真的不确定这里发生了什么......所以你没有在生产环境中获得编译过的文件？

我可能误解了您的问题，但您是否正在创建自己的css清单文件而不是application.css，例如assets / stylesheets / shared /？然后在你的production.rb（environment）文件中，你需要告诉Rails编译它们：

AppName::Application.configure do

# application.js, application.css, and all non-JS/CSS in app/assets folder are already added.
config.assets.precompile += ['shared/filename.css', 'shared2/filename2.css']

end

答案 1 :(得分：0)

运行RAILS_ENV=production bundle exec rake assets:precompile，然后添加，提交并将更改部署到生产中。
