Like here:

Sometimes you want to alternate layouts depending on the execution time of the information, for example, logged in or not. This can be done either by specifying the link method as a symbol or using the built-in method (like proc).

In short, when you specify a character, Rails actually expects it to be a reference to a method, so the reason it claims that no method was found.
