def add_target(targets, file, msgid) # :nodoc:
  key_existed = targets.assoc(msgid)

	targets[targets.index(key_existed)] = key_existed << "#{file}:-"
  else
	targets << [msgid, "#{file}:-"]
  end
  targets
end

.init(config) ⇒ Object

Sets some preferences to parse ActiveRecord files.

  • config: a Hash of the config. It can takes some values below:

    • :use_classname: If true, the msgids of ActiveRecord become “ClassName|FieldName” (e.g. “Article|Title”). Otherwise the ClassName is not used (e.g. “Title”). Default is true.

    • :db_yml: the path of database.yml. Default is “config/database.yml”.

    • :db_mode: the mode of the database. Default is “development”

    • :activerecord_classes: an Array of the superclass of the models. The classes should be String value. Default is [“ActiveRecord::Base”]

“ClassName|FieldName” uses GetText.sgettext. So you don’t need to translate the left-side of “|”. See <Documents for Translators for more details(www.yotabanana.com/hiki/ruby-gettext-translate.html)>.
