* Todo **manejado automáticamente** por el framework.
* Todas las dependencias pueden requerir datos de los requests y **aumentar las restricciones de la path operation** y la documentación automática.
* **Validación automática** incluso para los parámetros de *path operation* definidos en las dependencias.
* Soporte para sistemas de autenticación de usuario complejos, **conexiones a bases de datos**, etc.

Но далее я покажу, как это улучшить. 🤓

## Пользовательские ID операций и лучшие имена методов { #custom-operation-ids-and-better-method-names }

Вы можете **изменить** способ **генерации** этих ID операций, чтобы сделать их проще, а имена методов в клиентах — **более простыми**.

### Créer un chemin d'accès pour tester { #create-a-path-operation-to-test-it }

Maintenant, pour pouvoir vérifier que tout fonctionne, créez un chemin d'accès :

{* ../../docs_src/custom_docs_ui/tutorial001_py310.py hl[36:38] *}

### Tester { #test-it }

FastAPI artık şunları yapacak:

* Verinin uzunluğunun en fazla 50 karakter olduğundan emin olacak şekilde **doğrulayacak**
* Veri geçerli değilse client için **net bir hata** gösterecek
* Parametreyi OpenAPI şemasındaki *path operation* içinde **dokümante edecek** (dolayısıyla **otomatik dokümantasyon arayüzünde** görünecek)
