require 'active_support/core_ext/hash/reverse_merge'
module ActiveModel
# == Active Model Translation
#
# Provides integration between your object and the Rails internationalization
# (i18n) framework.
#
# A minimal implementation could be:
#
# class TranslatedPerson
# extend ActiveModel::Translation
# end
#
# TranslatedPerson.human_attribute_name('my_attribute')
# #=> "My attribute"
#
# This also provides the required class methods for hooking into the
# Rails internationalization API, including being able to define a
# class based i18n_scope and lookup_ancestors to find translations in
# parent classes.
module Translation
include ActiveModel::Naming
# Returns the i18n_scope for the class. Overwrite if you want custom lookup.
def i18n_scope
:activemodel
end
# When localizing a string, it goes through the lookup returned by this
# method, which is used in ActiveModel::Name#human,
# ActiveModel::Errors#full_messages and
# ActiveModel::Translation#human_attribute_name.
def lookup_ancestors
self.ancestors.select { |x| x.respond_to?(:model_name) }
end
# Transforms attribute names into a more human format, such as "First name"
# instead of "first_name".
#
# Person.human_attribute_name("first_name") # => "First name"
#
# Specify +options+ with additional translating options.
