module FriendlyId::Base

Set up a model to use a friendly_id. This method accepts a hash with {FriendlyId::Configuration several possible options}.

@param [#to_sym] method The column or method that should be used as the

basis of the friendly_id string.

@param [Hash] options For valid configuration options, see

{FriendlyId::Configuration}.

@param [block] block An optional block through which to filter the

friendly_id text; see {FriendlyId::Configuration#normalizer}. Note that
passing a block parameter is now deprecated and will be removed
from FriendlyId 3.0.

@example

class User < ActiveRecord::Base
  has_friendly_id :user_name
end

class Post < ActiveRecord::Base
  has_friendly_id :title, :use_slug => true, :approximate_ascii => true
end

@see FriendlyId::Configuration

# File lib/friendly_id.rb, line 49
def has_friendly_id(method, options = {}, &block)
  raise NotImplementedError
end

Does the model class use the FriendlyId plugin?

# File lib/friendly_id.rb, line 54
def uses_friendly_id?
  respond_to? :friendly_id_config
end
