Overview

Mobility is a gem for storing and retrieving localized data through attributes on a class. The Mobility module includes all necessary methods and modules to support defining backend accessors on a class.

To enable Mobility on a class, simply include or extend the Mobility module, and define any attribute accessors using Translates#mobility_accessor (aliased to the value of Mobility.accessor_method, which defaults to translates).

class MyClass
  include Mobility
  translates :title, backend: :key_value
end

When defining this module, Mobility attempts to require various gems (for example, active_record and sequel) to evaluate which are loaded. Loaded gems are tracked with dynamic subclasses of the Loaded module and referenced in backends to define gem-dependent behavior.
