资产管道：排除 admin.css 文件
我将 Rails 3.0 应用程序升级到 Rails 3.1，其中涉及将其放入
/*
*= require_self
*= require_tree .
*/
application.css 文件中。但是，有一个 admin.css 文件现在覆盖了主应用程序 css 文件。
有没有办法排除 admin.css 文件被包含？在网站的管理部分，我手动包含 admin.css 文件，但我需要一种方法将其从用户界面中排除。
I upgraded a Rails 3.0 app to Rails 3.1 which involved putting this
/*
*= require_self
*= require_tree .
*/
in the application.css file. However, there's an admin.css file that's now overriding the main app css file.
Is there a way to exclude the admin.css file from being included? In the admin section of the site I manually include the admin.css file but I need a way to exclude it from the user interface.

您可以在清单中使用
stubsprockets' 指令，如下所示：这将排除
admin.css以及其中所需的 ALL css！因此，如果您的
admin.css的清单看起来像这样：bootstrap.css也将被排除，并且没有require可以解决这个问题！照顾好这个；）You can use the
stubsprockets' directive in your manifest like this :This will exclude
admin.cssand also ALL css required in it !!So, if your
admin.css's manifest seems like this :the
bootstrap.csswill also be excludes and norequirecould fixe this ! Take care of this ;)之前曾提出过类似问题，您应该检查一下一个。
Sprockets 使用清单文件来确定要包含和提供哪些资产。这些清单文件包含指令——告诉 Sprockets 构建单个 CSS 或 JavaScript 文件需要哪些文件的指令。使用这些指令，Sprockets 加载指定的文件，在必要时处理它们，将它们连接成一个文件，然后压缩它们（如果 Rails.application.config.assets.compress 为 true）。通过提供一个文件而不是多个文件，可以大大减少页面的加载时间，因为浏览器发出的请求更少。
您可以根据需要拥有任意数量的清单文件。例如，admin.css 和 admin.js 清单可以包含用于应用程序管理部分的 JS 和 CSS 文件。
特别是，您可以指定单个文件，它们会按照指定的顺序进行编译。
示例和更多详细信息可以在本指南中找到。
因此，您的新 application.css 将变为：
Similar question was asked earlier and you should check that one.
Sprockets uses manifest files to determine which assets to include and serve. These manifest files contain directives — instructions that tell Sprockets which files to require in order to build a single CSS or JavaScript file. With these directives, Sprockets loads the files specified, processes them if necessary, concatenates them into one single file and then compresses them (if Rails.application.config.assets.compress is true). By serving one file rather than many, the load time of pages can be greatly reduced because the browser makes fewer requests.
You can have as many manifest files as you need. For example the admin.css and admin.js manifest could contain the JS and CSS files that are used for the admin section of the application.
In particular, you can specify individual files and they are compiled in the order specified.
Example and more details can be found in this guide.
Thus, your new application.css would become:
另一种解决方案是在
app/assets/stylesheets中有两个目录，例如public目录和admin目录。然后，在
app/assets/stylesheets/application.css中，您可以将require_tree .更改为require_tree ./public。您可能需要在管理方面执行类似的操作。我碰巧正在使用 管理 gem，它知道在哪里可以找到自己的资产。
Another solution is to have two directories in
app/assets/stylesheets, for example, apublicdirectory and anadmindirectory.Then, in
app/assets/stylesheets/application.css, you can changerequire_tree .torequire_tree ./public.You might have to do something similar on the admin side. I happen to be using the Administrate gem which knows where to find its own assets.
解决方案是在 config/assets.rb 中添加
并在 app/views/layouts/_adm_layout.html.erb 中添加
soluction is add in config/assets.rb
And Add in app/views/layouts/_adm_layout.html.erb
