ActionController::RoutingError (No route matches [GET] “/favicon.ico”) in Rails

Question

I have tried to use

as well as this

Answer 1

Putting favicon.ico in my public folder wasn't working, so I combined some of the other answers to come up with this simple working method.

Copy the output of favicon_link_tag and inject image_path like so:

" rel="shortcut icon" type="image/vnd.microsoft.icon" />

Now place favicon.ico in your assets/images folder and you're set.
