我在rails中使用google amp兼容页面的网站布局有以下rails模板,它正在开发中,但样式表无法在生产中编译
<!doctype html>
<html ⚡>
<head>
<title>
<%= App.title %>
</title>
<%= render 'layouts/meta' %>
<style amp-boilerplate>
body{-webkit-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-moz-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:-amp-start 8s steps(1,end) 0s 1 normal both;animation:-amp-start 8s steps(1,end) 0s 1 normal both}@-webkit-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}
</style>
<style amp-custom>
<%= Rails.application.assets.find_asset('amp').to_s.gsub('@charset "UTF-8";', '').html_safe %>
</style>
<script async src="https://cdn.ampproject.org/v0.js"></script>
</head>
<body>
<%= render 'layouts/header' %>
<%= yield %>
<%= render 'layouts/footer' %>
</body>
</html>

看起来并不太难。您可以添加以下帮助程序,我在vyachkonovalov
中找到将以下内容添加到erb
模板中:
<style amp-custom>
<%= asset_to_string('amp.css').html_safe %>
</style>
ApplicationHelper
的助手。它在本地和生产中都能很好地工作。
module ApplicationHelper
def asset_to_string(name)
app = Rails.application
if Rails.configuration.assets.compile
app.assets.find_asset(name).to_s
else
controller.view_context.render(file: File.join('public/assets', app.assets_manifest.assets[name]))
end
end

您可以使用内置的Sass功能来压缩scss文件。
例如,在您的application_helper文件中:
def amp_stylesheet
amp_css = Rails.application.assets['amp/application'].to_s
if amp_css.count('\n') > 2
::Sass::Engine.new(amp_css, syntax: :scss, style: :compressed).render
else
amp_css
end
end
在你的布局文件中:
<style amp-custom>
<%= amp_stylesheet.html_safe %>
</style>
