Instance Method Details

#gettext_model_name_msgid ⇒ Object

Canonical msgid for a model name is the raw class name (see #207), e.g. “SomeNamespace::SomeModel” – consistent with human_attribute_name.

def gettext_model_name_msgid
  gettext_resolve_legacy_msgid(to_s, humanize_class_name)
end

#gettext_resolve_legacy_msgid(current, legacy) ⇒ Object

Returns current, unless only the legacy msgid resolves to a translation – then legacy is returned and a deprecation is warned once. Keeps pre-#207 .po files working during the transition.
