Rails ActionController::UnknownAction for favicon

I have following line in my app/views/layouts/application.html.erb

<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />

ActionController::UnknownAction (No action responded to images. Actions: 

How to get rid of it ?

Use the favicon_link_tag helper instead:

<%= favicon_link_tag "/favicon.ico" %>

Just make sure your favicon.ico file is in the public folder... and do not forget the forward slash.

Believe me.. try prefixing images with a slash and this should work

<link rel="shortcut icon" href="/images/favicon.ico" type="image/x-icon" />
