### Tags with Enums { #tags-with-enums }

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

    assertThat(Enums.getIfPresent(TestEnum.class, "POODLE")).hasValue(TestEnum.POODLE);

    assertThat(Enums.getIfPresent(TestEnum.class, "CHEETO")).isPresent();
    assertThat(Enums.getIfPresent(TestEnum.class, "HONDA")).isPresent();
    assertThat(Enums.getIfPresent(TestEnum.class, "POODLE")).isPresent();

    assertThat(Enums.getIfPresent(TestEnum.class, "CHEETO")).hasValue(TestEnum.CHEETO);

    assertThat(Enums.getIfPresent(TestEnum.class, "POODLE")).hasValue(TestEnum.POODLE);

    assertThat(Enums.getIfPresent(TestEnum.class, "CHEETO")).isPresent();
    assertThat(Enums.getIfPresent(TestEnum.class, "HONDA")).isPresent();
    assertThat(Enums.getIfPresent(TestEnum.class, "POODLE")).isPresent();

    assertThat(Enums.getIfPresent(TestEnum.class, "CHEETO")).hasValue(TestEnum.CHEETO);

這些標籤會被加入到 OpenAPI 結構描述，並由自動化文件介面使用：

### 含 Enum 的標籤 { #tags-with-enums }

如果你的應用很大，可能會累積數個標籤，你會希望對相關的「路徑操作」始終使用相同的標籤。

在這種情況下，可以考慮把標籤存放在 `Enum` 中。

**FastAPI** 對此的支援方式與使用普通字串相同：

{* ../../docs_src/path_operation_configuration/tutorial002b_py310.py hl[1,8:10,13,18] *}

## 摘要與描述 { #summary-and-description }

これらはOpenAPIスキーマに追加され、自動ドキュメントのインターフェースで使用されます:

### Enumを使ったタグ { #tags-with-enums }

大きなアプリケーションの場合、**複数のタグ**が蓄積されていき、関連する*path operations*に対して常に**同じタグ**を使っていることを確認したくなるかもしれません。

このような場合、タグを`Enum`に格納すると理にかなっています。

**FastAPI** は、プレーンな文字列の場合と同じ方法でそれをサポートしています:

{* ../../docs_src/path_operation_configuration/tutorial002b_py310.py hl[1,8:10,13,18] *}

### Tags con Enums { #tags-with-enums }

Si tienes una gran aplicación, podrías terminar acumulando **varias tags**, y querrías asegurarte de que siempre uses la **misma tag** para *path operations* relacionadas.

En estos casos, podría tener sentido almacenar las tags en un `Enum`.

**FastAPI** soporta eso de la misma manera que con strings normales:

<img src="/img/tutorial/path-operation-configuration/image01.png">

### Tags com Enums { #tags-with-enums }

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a ** mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:

    /**
     * Identifier used to encode this strategy, when marshalled as part of a BloomFilter. Only
     * values in the [-128, 127] range are valid for the compact serial form. Non-negative values
     * are reserved for enums defined in BloomFilterStrategies; negative values are reserved for any
     * custom, stateful strategy we may define (e.g. any kind of strategy that would depend on user
     * input).
     */
    int ordinal();
