Instance Method Details

#define_enum_t_methods ⇒ Object

enum attrubute_t and attributes_t return translated enum values

Example:

in the Client model
  enum gender: { undefined: 0, female: 1, male: 2 }
in use
  Client.first.gender    # => 'female'
  Client.first.gender_t  # => 'Frau'
  Client.first.genders_t # => { undefined: 'Nicht definiert', female: 'Frau', male: 'Mann' }

Requires:

locale key: activerecord.attributes.#{model_name}.#{enum}.#{enum_value_key}
eg.:        activerecord.attributes.client.genders.female                    # => 'Frau'
