/// tip

You could use the same technique to extend the JSON Schema and add your own custom extra info.

For example you could use it to add metadata for a frontend user interface, etc.

///

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

* Methods.
* Request payloads in the body, query parameters, etc.
* Response payloads.

You would also have **inline errors** for everything.

And whenever you update the backend code, and **regenerate** the frontend, it would have any new *path operations* available as methods, the old ones removed, and any other change would be reflected on the generated code. 🤓

And the spec says that the fields have to be named like that. So `user-name` or `email` wouldn't work.

But don't worry, you can show it as you wish to your final users in the frontend.

And your database models can use any other names you want.

// RUnlock - block until read lock is released.
func (di *distLockInstance) RUnlock(lc LockContext) {
	if lc.cancel != nil {
		lc.cancel()
	}
	di.rwMutex.RUnlock(lc.ctx)
}

// localLockInstance - frontend/top-level interface for namespace locks.
type localLockInstance struct {
	ns     *nsLockMap
	volume string
	paths  []string
	opsID  string
}

// NewNSLock - returns a lock instance for a given volume and

# Handling Errors { #handling-errors }

There are many situations in which you need to notify an error to a client that is using your API.

This client could be a browser with a frontend, a code from someone else, an IoT device, etc.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

Ayrıca, API'nızla iletişim kuran istemciler için otomatik olarak kod üretmekte de kullanabilirsiniz. Örneğin frontend, mobil veya IoT uygulamaları.

### `pyproject.toml` içinde uygulama `entrypoint`'ını yapılandırın { #configure-the-app-entrypoint-in-pyproject-toml }

También podrías usarlo para generar código automáticamente, para clientes que se comuniquen con tu API. Por ejemplo, aplicaciones frontend, móviles o IoT.

### Configura el `entrypoint` de la app en `pyproject.toml` { #configure-the-app-entrypoint-in-pyproject-toml }

Puedes configurar dónde está tu app en un archivo `pyproject.toml` así:

```toml

Vous pourriez également l’utiliser pour générer du code automatiquement, pour les clients qui communiquent avec votre API. Par exemple, des applications frontend, mobiles ou IoT.

### Configurer le `entrypoint` de l’application dans `pyproject.toml` { #configure-the-app-entrypoint-in-pyproject-toml }

## About third party integrations { #about-third-party-integrations }

In this example we are using the OAuth2 "password" flow.

This is appropriate when we are logging in to our own application, probably with our own frontend.

Because we can trust it to receive the `username` and `password`, as we control it.
