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.
# File activemodel/lib/active_model/translation.rb, line 44 def human_attribute_name(attribute, options = {}) options = { count: 1 }.merge!(options) parts = attribute.to_s.split(".") attribute = parts.pop namespace = parts.join("/") unless parts.empty? attributes_scope = "#{i18n_scope}.attributes" if namespace defaults = lookup_ancestors.map do |klass| :"#{attributes_scope}.#{klass.model_name.i18n_key}/#{namespace}.#{attribute}" end defaults << :"#{attributes_scope}.#{namespace}.#{attribute}" else defaults = lookup_ancestors.map do |klass| :"#{attributes_scope}.#{klass.model_name.i18n_key}.#{attribute}" end end defaults << :"attributes.#{attribute}" defaults << options.delete(:default) if options[:default] defaults << attribute.humanize options[: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 ActiveModel::Translation#human_attribute_name
.
