  file_lineno = "#{file}:-"
  key_existed = targets.assoc(msgid)
  if key_existed and ! targets[targets.index(key_existed)].include?(file_lineno)

  targets

.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”]

    • :untranslate_columns - an Array of the column names which is ignored as the msgid.

    • :adapter - the options for ActiveRecord::Base.establish_connection. If this value is set, :db_yml option is ignored.

    • :host - ditto

    • :username - ditto

    • :password - ditto

    • :database - ditto

    • :socket - ditto

    • :encoding - ditto

“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)>.
