## Documentation automatique

Les schémas JSON de vos modèles seront intégrés au schéma OpenAPI global de votre application, et seront donc affichés dans la documentation interactive de l'API :

simply of `DCE 1.1 v4 UUID 4` (random data based), UUIDs are 128 bit numbers which are intended to have a high likelihood of uniqueness over space and time and are computationally difficult to guess. They are globally unique identifiers which can be locally generated without contacting a global registration authority. UUIDs are intended as unique identifiers for both mass tagging objects with an extremely short lifetime and to reliably identifying very persistent objects across a network.

When...

Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).

Nesse cenário, se você precisa manipular essa exceção de modo global com o FastAPI, você pode adicionar um manipulador de exceção customizada com `@app.exception_handler()`.

```Python hl_lines="5-7  13-18  24"

Il installera toutes les dépendances et votre FastAPI local dans votre environnement local.

#### Utiliser votre FastAPI local

Si vous créez un fichier Python qui importe et utilise FastAPI, et que vous l'exécutez avec le Python de votre environnement local, il utilisera votre code source FastAPI local.

| HOST_PROBE_SNAT_IP | "169.254.7.127" | Applied to SNAT host probe packets, so they can be identified/skipped podside. Any link-local address in the 169.254.0.0/16 block can be used |
| HOST_PROBE_SNAT_IPV6 | "fd16:9254:7127:1337:ffff:ffff:ffff:ffff" | IPv6 link local ranges are designed to be collision-resistant by default, and so this probably never needs to be overridden |

## Sidecar Mode Implementation Details

### Import `FastAPI`

You import and create a `FastAPI` class as normally.

And we can even declare [global dependencies](dependencies/global-dependencies.md){.internal-link target=_blank} that will be combined with the dependencies for each `APIRouter`:

```Python hl_lines="1  3  7" title="app/main.py"

## Settings in a dependency

In some occasions it might be useful to provide the settings from a dependency, instead of having a global object with `settings` that is used everywhere.

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file

            * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.
                * **FastAPI** adds a reference here to the global JSON Schemas in another place in your OpenAPI instead of including it directly. This way, other applications and clients can use those JSON Schemas directly, provide better code generation tools, etc.

### `FastAPI` importieren

Sie importieren und erstellen wie gewohnt eine `FastAPI`-Klasse.

Und wir können sogar [globale Abhängigkeiten](dependencies/global-dependencies.md){.internal-link target=_blank} deklarieren, die mit den Abhängigkeiten für jeden `APIRouter` kombiniert werden:

```Python hl_lines="1  3  7" title="app/main.py"
