What is the rails way to do this? I'm using Rails 2.3.10

Error is: undefined local variable or method `favicon_link_tag' for #<ActionView::Base:0xb6e57034>

This module is needed I guess: ActionView::Helpers::AssetTagHelper

Here is what I did: app/views/layouts/application.html.haml !!! 5 %html   %head     %title App1 - Rails Way     = favicon_link_tag   %body     #content       = yield

Where would you expect favicon_link_tag to be defined? The error message is accurate.

I'm just learning rails and trying to learn the rails way. I expected that module ActionView::Helpers::AssetTagHelper would be available in the view.

It is. But favicon_link_tag is not defined in there, at least according to the docs. Where did you get the idea that this method even exists?

Alright, I've now learned that the method was introduced in Rails 3.0.0. Your responses strike me as rude, but I have learned somthing.

They were not meant to be rude. I was merely trying to figure out why you would expect an apparently nonexistent method to work. I didn't know that APIdock had that "helpful" (?) feature of displaying methods that don't actually exist...

BTW, I recommend http://www.railsbrain.com for Rails docs.

'build your custom package' at railsapi.com looks like my new goto Rails documentation.

Also, I was really not understanding the version information on favicon_link_tag and that had me confused and frustrated. Thanks for your help.
