end

.import_from_yaml(options = {}) ⇒ Object

This method imports yaml translations to the couchdb version. When run again new ones will be added. Translations already stored in the couchdb database are not overwritten if true or ovveride_existing: true is given

.indent_keys(selection = CouchI18n::Translation.all) ⇒ Object

This will return an indented strucutre of a collection of stores. If no argument is given by default all the translations are indented. So a command:

CouchI18n.indent_keys.to_yaml will return one big yaml string of the translations
