TranslateableAttributes

Helper methods to display translated values of object attributes.

Installation

Add this line to your application's Gemfile:

gem 'translateable_attributes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install translateable_attributes

Usage

Setup your translations:

en:
  states:
    new: 'Initiated'
    completed: 'Done'

Extend a class with TranslateableAttributes::Methods and call translate_attributes method on it:

class TranslatedClass
  extend TranslateableAttributes::Methods

  translate_attributes state: 'states'
end

Use translated_attribute class and instance methods to display translated values:

TranslatedClass.translated_state('new') #=> 'Initiated'

translated_instance = TranslatedClass.new
translated_instance.state = 'new'
translated_instance.translated_state #=> 'Initiated'

In addition, attributes_for_select class method is defined that returns all available [translation, value] pairs - useful for select inputs in Rails form builders.

TranslatedClass.states_for_select #=> [['Initiated', 'new'], ['Done', 'completed']]

translate_attributes class method accepts a hash of attribute_name: 'translation.namespace'. Translations are looked up by appending attribute value to provided namespace and passing that to I18n.t method.

For example, given Klass.translate_attributes state: 'some.nested.translation.namespace', calling Klass.translated_state 'new' equals to I18n.t 'some.nested.translation.namespace.new'.
