## Aider les autres à résoudre les problèmes dans GitHub

Vous pouvez voir <a href="https://github.com/fastapi/fastapi/issues" class="external-link" target="_blank">les problèmes existants</a> et essayer d'aider les autres, la plupart du temps il s'agit de questions dont vous connaissez peut-être déjà la réponse. 🤓

## Atualização de dados existentes com `PUT`

Para atualizar um item, você pode usar a operação <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

Você pode usar `jsonable_encoder` para converter os dados de entrada em dados que podem ser armazenados como JSON (por exemplo, com um banco de dados NoSQL). Por exemplo, convertendo `datetime` em `str`.

     * path if the project directory is given as an absolute path.
     *
     * @param projectDirectory The (possibly non-existent) base directory to locate the POM file in, must not be {@code
     *            null}.
     * @return The path to the (possibly non-existent) POM file, never {@code null}.
     * @deprecated Use {@link #locatePom(Path)} instead.
     */
    @Deprecated
    File locatePom(File projectDirectory);

    /**
     * Gets the global settings file.
     *
     * @return The global settings file or {@code null} if none.
     */
    File getGlobalSettingsFile();

    /**
     * Sets the global settings file. A non-existent settings file is equivalent to empty settings. If both user
     * settings and global settings are given, the user settings take precedence.

### Vet

The new `tests` analyzer reports common mistakes in declarations of
tests, fuzzers, benchmarks, and examples in test packages, such as
malformed names, incorrect signatures, or examples that document
non-existent identifiers. Some of these mistakes may cause tests not
to run.

    assert response.status_code == 401, response.text
    assert response.json() == {"detail": "Not authenticated"}


def test_incorrect_token():
    response = client.get("/items", headers={"Authorization": "Non-existent testtoken"})
    assert response.status_code == 401, response.text
    assert response.json() == {"detail": "Not authenticated"}


def test_token():

    assert response.status_code == 401, response.text
    assert response.json() == {"detail": "Not authenticated"}


def test_incorrect_token():
    response = client.get("/items", headers={"Authorization": "Non-existent testtoken"})
    assert response.status_code == 401, response.text
    assert response.json() == {"detail": "Not authenticated"}


def test_token():

Por ejemplo, digamos que quieres tener una *operación de path* que permita actualizar ítems y devolver códigos de estado HTTP 200 "OK" cuando sea exitosa.

Pero también quieres que acepte nuevos ítems. Cuando los ítems no existan anteriormente, serán creados y devolverá un código de estado HTTP 201 "Created".

Para conseguir esto importa `JSONResponse` y devuelve ahí directamente tu contenido, asignando el `status_code` que quieras:

	fileModified, errChan := make(chan struct{}), make(chan error)
	go watchFiles(watcher, fileModified, errChan)

	for _, path := range paths {
		if !file.Exists(path) {
			log.Infof("file watcher skipping watch on non-existent path: %v", path)
			continue
		}
		if err := watcher.Add(path); err != nil {
			if closeErr := watcher.Close(); closeErr != nil {
				err = fmt.Errorf("%s: %w", closeErr.Error(), err)
			}
			return nil, err
		}

Par exemple, il était clair que l'idéal était de se baser sur les annotations de type Python standard.

De plus, la meilleure approche était d'utiliser des normes déjà existantes.

Ainsi, avant même de commencer à coder **FastAPI**, j'ai passé plusieurs mois à étudier les spécifications d'OpenAPI, JSON Schema, OAuth2, etc. Comprendre leurs relations, leurs similarités et leurs différences.
