`PUT` is used to receive data that should replace the existing data.

### Warning about replacing { #warning-about-replacing }

That means that if you want to update the item `bar` using `PUT` with a body containing:

```Python
{
    "name": "Barz",

    * **WebSockets**
    * des tests extrêmement faciles basés sur HTTPX et `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ... et plus encore.

### Déployer votre application (optionnel) { #deploy-your-app-optional }

Vous pouvez, si vous le souhaitez, déployer votre application FastAPI sur [FastAPI Cloud](https://fastapicloud.com), allez vous inscrire sur la liste d'attente si ce n'est pas déjà fait. 🚀

# Background Tasks { #background-tasks }

You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

   * graph implementations, this method should replace {@link #graph} with a new graph that includes
   * this node.
   */
  abstract void addNode(Integer n);

  /**
   * A proxy method that adds the edge {@code e} to the graph being tested. In case of Immutable
   * graph implementations, this method should replace {@link #graph} with a new graph that includes
   * this edge.
   */

        response.header("Content-Disposition", "attachment; filename=\"" + name + "\"; filename*=utf-8''" + encodedName);
        response.header("Pragma", "no-cache");
