/// tip

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

And you will also see the amounts of code it will save you.

# Общее — Как сделать — Рецепты { #general-how-to-recipes }

Здесь несколько указателей на другие места в документации для общих или частых вопросов.

## Фильтрация данных — Безопасность { #filter-data-security }

Чтобы убедиться, что вы не возвращаете больше данных, чем следует, прочитайте документацию: [Руководство — Модель ответа — Возвращаемый тип](../tutorial/response-model.md){.internal-link target=_blank}.

Aber in realen Fällen würden Sie bei der Implementierung von Sicherheit mehr Vorteile durch die Verwendung der integrierten [Sicherheits-Werkzeuge (siehe nächstes Kapitel)](../security/index.md){.internal-link target=_blank} erzielen.

## Abhängigkeitsfehler und -Rückgabewerte { #dependencies-errors-and-return-values }

### Sicherheit und Authentifizierung { #security-and-authentication }

Sicherheit und Authentifizierung sind integriert. Ohne Kompromisse bei Datenbanken oder Datenmodellen.

Alle in OpenAPI definierten Sicherheitsschemas, inklusive:

* HTTP Basic.
* **OAuth2** (auch mit **JWT Tokens**). Siehe dazu das Tutorial zu [OAuth2 mit JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API Schlüssel in:

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

{* ../../docs_src/handling_errors/tutorial001_py39.py hl[11] *}

* **출력 모델** 은 비밀번호를 가지면 안됩니다.
* **데이터베이스 모델** 은 해시처리된 비밀번호를 가질 것입니다.

/// danger | 위험

절대 사용자의 비밀번호를 평문으로 저장하지 마세요. 항상 이후에 검증 가능한 "안전한 해시(secure hash)"로 저장하세요.

만약 이게 무엇인지 모르겠다면, [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.에서 비밀번호 해시에 대해 배울 수 있습니다.

## 다중 모델

아래는 비밀번호 필드와 해당 필드가 사용되는 위치를 포함하여, 각 모델들이 어떤 형태를 가질 수 있는지 전반적인 예시입니다:

# Maintenance Mode

**This project is currently under maintenance and is not accepting new changes.**

- The codebase is in a maintenance-only state
- No new features, enhancements, or pull requests will be accepted
- Critical security fixes may be evaluated on a case-by-case basis
- Existing issues and pull requests will not be actively reviewed
- Community support continues on a best-effort basis through [Slack](https://slack.min.io)
