# By default, changes to the layout temnplate won't cause a Rails etag
# to change. I suppose this is to facilitate Turbolinks. Sometimes you
# might want to change an etag in response to changes in the layout -
# this is particularly true when working in development mode. This is
# one way to do it, there are probably other (read: likely better) ways
# to do this too.
class FooController < ApplicationController
  # There's probably some API method to get the name of the layout
  # rather than hard-coding it like I did here, but I'm too lazy to
  # look it up right now.

FriendlyId uses Rails's extending method to avoid overwriting your model's find method. Internally this is implemented similar to this:

def self.friendly
  all.extending(friendly_id_config.finder_methods)
end

This however comes with a performance impact, because extending invokes Ruby's extend, which blows away MRI's method cache. To work around this, FriendlyId lets you include a :finders module which overrides your model's find to increase performance.

        def build_#{underscored}(attributes = {})
          attributes = valid_#{underscored}_attributes.deep_merge(attributes)
          #{name}.new(attributes)
