html - css 没有在 rails 4.2.5.1 中应用？

Question

“我在 rails 中生成 Controller ，它会为我生成 css，但是当我在 Assets /样式表 controller_name.scss.css 中添加 css 时，它不会被包含在内，但是当我将它本身添加到 html 文件中时，它会到达那里。”

“这是我的 controller_name.scss.css 文件”

// Place all the styles related to the boo controller here.
// They will automatically be included in application.css.
// You can use Sass (SCSS) here: http://sass-lang.com/
h1 { color:#77eeff;
    text-align: center;
    text-decoration: underline;}

这是 application.css

/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over    styles    defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.

请将“controller_name.scss.css”文件更改为“controller_name.css.scss”，据我所知，预处理器扩展应该链接在末尾。此外，如果您的应用程序环境是“生产环境”，那么您必须运行:

bundle exec production rake assets:precompile

如果是开发，那么就运行:

抽取 Assets :预编译
