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

```
코드를 확인해 보니:
```plaintext
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:
```plaintext
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.

@dorina, 이 문제는 [FIX: Incorrect lang mapping using non-symbols for LibreTranslate - Pull Request #238 - discourse/discourse-translator - GitHub](https://github.com/discourse/discourse-translator/pull/238) 에서 수정되었습니다. 이 수정 사항을 적용하기 위해 플러그인을 업데이트할 수 있습니다.
