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.
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.
Source: show
# File activemodel/lib/active_model/translation.rb, line 45 def human_attribute_name(attribute, options = {}) defaults = lookup_ancestors.map do |klass| :"#{self.i18n_scope}.attributes.#{klass.model_name.i18n_key}.#{attribute}" end defaults << :"attributes.#{attribute}" defaults << options.delete(:default) if options[:default] defaults << attribute.to_s.humanize options.reverse_merge! :count => 1, :default => defaults I18n.translate(defaults.shift, options) end
Returns the i18n_scope
for the class. Overwrite if you want
custom lookup.

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 #human_attribute_name.
