'Back' browser action in Ruby on Rails

Question

Can the 'Back' browser functionality be invoked from a Rails 'Back' link?

Answer 1

Use

<%= link_to 'Back', :back %> 

This is specificied in the RDoc here

This generates some Javascript to navigate backward. I've just tested it, and it works.

Answer 2

In Rails 3 and earlier:

link_to_function "Back", "history.back()" 

In Rails 4, this method has been removed. See Andreas's comment.
