How do I create dynamic CSS in Rails?

Question

what is the best/most efficient way of creating dynamic CSS with Rails. I am developing an admin area on a site, where I would like a user to be able to customize the style

Answer 1

You can use ERB with CSS, you just need to render css in the controller. However, for such a heavily requested resource, I do not recommend generating this every time. I would store the users stylesheet in memcached or redis, and recall from it when the page loads, rather than rerendering the file each time. When they update their style, you can expire the cache, just make sure it gets rebuilt when the page renders.
