module FriendlyId
=begin
## Reserved Words
The {FriendlyId::Reserved Reserved} module adds the ability to exclude a list of
words from use as FriendlyId slugs.
With Ruby on Rails, FriendlyId's generator generates an initializer that
reserves some words such as "new" and "edit" using {FriendlyId.defaults
FriendlyId.defaults}.
Note that the error messages for fields will appear on the field
`:friendly_id`. If you are using Rails's scaffolded form errors display, then
it will have no field to highlight. If you'd like to change this so that
scaffolding works as expected, one way to accomplish this is to move the error
message to a different field. For example:
class Person < ActiveRecord::Base
extend FriendlyId
friendly_id :name, use: :slugged
after_validation :move_friendly_id_error_to_name
def move_friendly_id_error_to_name
errors.add :name, *errors.delete(:friendly_id) if errors[:friendly_id].present?
end
end
=end
module Reserved
# When included, this module adds configuration options to the model class's
# friendly_id_config.
def self.included(model_class)
model_class.class_eval do
friendly_id_config.class.send :include, Reserved::Configuration
validates_exclusion_of :friendly_id, :in => ->(_) {
friendly_id_config.reserved_words || []
}
end
end
# This module adds the `:reserved_words` configuration option to
# {FriendlyId::Configuration FriendlyId::Configuration}.
module Configuration
attr_accessor :reserved_words
end
end
