Method: FriendlyId::Slugged#normalize_friendly_id

Defined in:

lib/friendly_id/slugged.rb

#normalize_friendly_id(value) ⇒ Object

Process the given value to make it suitable for use as a slug.

This method is not intended to be invoked directly; FriendlyId uses it internally to process strings into slugs.

However, if FriendlyId's default slug generation doesn't suit your needs, you can override this method in your model class to control exactly how slugs are generated.

Example

class Person < ActiveRecord::Base
  extend FriendlyId
  friendly_id :name_and_location

  def name_and_location
    "#{name} from #{location}"
  end

  # Use default slug, but upper case and with underscores
  def normalize_friendly_id(string)
    super.upcase.gsub("-", "_")
  end
end

bob = Person.create! :name => "Bob Smith", :location => "New York City"
bob.friendly_id #=> "BOB_SMITH_FROM_NEW_YORK_CITY"
