Discourse Translator를 설치하고 자체 호스팅한 LibreTranslate 인스턴스와 함께 사용하려고 했습니다. 작동하지 않았고 다음과 같은 백트레이스가 나타났습니다:

코드를 확인해 보니:
def self.translate!(translatable, target_locale_sym = I18n.locale)
detected_lang = detect(translatable)
save_translation(translatable, target_locale_sym) do
res =
result(
translate_uri,
q: text_for_translation(translatable),
source: detected_lang,
target: SUPPORTED_LANG_MAPPING[target_locale],
format: "html",
)
res["translatedText"]
end
end
특히 107번째 줄인 다음 코드입니다:
target: SUPPORTED_LANG_MAPPING[target_locale]
→ ‘target_locale’ 대신 'target_locale_sym’이어야 하는 것 같습니다. 제가 잘못 본 건가요?
수동으로 **target: SUPPORTED_LANG_MAPPING[target_locale_sym],**로 변경하고 저장한 뒤 앱을 재시작했는데 정상적으로 작동했습니다.
