Dynamic css - wrong content type

I need to add customizable interface for each user in my app. So after some googling i decided to generate css, cache it for every user and link it in views. I found good post and used it as example.

So there is pieces of resulting code from my app:

In controller shedule_themes_controller.rb:

...
def get_css
  respond_to do |format|
    format.css { render :text => "body {\n background-color: blue; \n}", :content_type => Mime::CSS }
  end
end

In layout:

...
<%= stylesheet_link_tag    "application" %>
<link href="<%= get_css_path %>" media="screen" rel="stylesheet" type="text/css" />

But when i start application, the css doesnt't load. It comes 406 Not Acceptable Error. And response headers are:

Cache-Control:no-cache, private
Connection:Keep-Alive
Content-Length:1
Content-Type:text/html; charset=utf-8

So as you see, response has content/type text/html so 406 error is.

Can anyone explain me, why controller response with text/html if request content-type is text/css ?

P.S. I tried to manually send request to localhost:3000/get_css using Google Chrome DEV HTTP CLIENT. I set up Content-Type: text/css and server responded with right css and content-type:

body {
  background-color: blue; 
}

So probably i made some mistakes in linking dynamic css in my layout?

Thank you!

The problem seems to be in the requested url. <%= get_css_path %> will return /get_css and hence the controller action with handle this request by the format.html part. So you can try to append the format with the url as:

<link href="<%= get_css_path(:format => :css) %>" media="screen" rel="stylesheet" type="text/css" />

This will request /get_css.css and hence the action will handle with format.css part.
