Rails 3 Team to Insert Text of My CSS Styles into the Head of My HTML

Question

Heroku gives the following advice for anyone using HyPDF to convert HTML to PDF:

Place your styles and scripts within <style> and <script> tags instead of loading them using <link> tag.

I am currently using the following:

 = stylesheet_link_tag "print", :media => "print, screen, projection" 

What is the Rails 3.2 code to generate the <style> equivalent with inline unlinked CSS?

(That is, with Rails, it automatically inserts all the CSS from /app/assets/stylesheets/print.scss into the HTML that it generates, instead of manually copying all these CSS into the content_tag and then saving the contents of this tag.)

Could not find anything in the API docs.

Thanks.

Paste the following code directly into the chapter section of your application. html.erb should work:

 <style> <%= render :file => Rails.application.assets.find_asset('print') %> </style> 

Of course, if you include stylesheets from several different views, instead you want to set up revenue in application.html.erb:

 <style> <%= yield(:inline_style) %> </style> 

Then from each view:

 <% content_for :inline_style %> <%= render :file => Rails.application.assets.find_asset('**stylesheet name**') %> <% end %>
