burgers = get_burgers(2)
```

Así que, si estás usando un paquete que te dice que puedes llamarlo con `await`, necesitas crear las *path operation functions* que lo usen con `async def`, como en:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

// getUserWithProvider - returns the appropriate internal username based on the user provider.
// if validate is true, an error is returned if the user does not exist.
func getUserWithProvider(ctx context.Context, userProvider, user string, validate bool) (string, error) {
	switch userProvider {
	case madmin.BuiltinProvider:

			if _, ok := globalIAMSys.GetUser(ctx, user); !ok {
				return "", errNoSuchUser

## Get the user { #get-the-user }

`get_current_user` will use a (fake) utility function we created, that takes a token as a `str` and returns our Pydantic `User` model:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Inject the current user { #inject-the-current-user }

So now we can use the same `Depends` with our `get_current_user` in the *path operation*:

 *
 * <p><b>Note:</b> by default, the returned map uses equality comparisons (the {@link Object#equals
 * equals} method) to determine equality for keys or values. However, if {@link #weakKeys} was
 * specified, the map uses identity ({@code ==}) comparisons instead for keys. Likewise, if {@link
 * #weakValues} was specified, the map uses identity comparisons for values.

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// info

`Form` is a class that inherits directly from `Body`.

///

/// tip

To declare form bodies, you need to use `Form` explicitly, because without it the parameters would be interpreted as query parameters or body (JSON) parameters.

Keep in mind that dataclasses can't do everything Pydantic models can do.

So, you might still need to use Pydantic models.

But if you have a bunch of dataclasses laying around, this is a nice trick to use them to power a web API using FastAPI. 🤓

///

## Dataclasses in `response_model` { #dataclasses-in-response-model }

You can also use `dataclasses` in the `response_model` parameter:

    /** Prefix used to identify role-based permissions */
    protected String rolePrefix = "{role}";

    /** Prefix used to identify group-based permissions */
    protected String groupPrefix = "{group}";

    /** Prefix used to identify user-based permissions */
    protected String userPrefix = "{user}";

    /** Prefix used to identify allow permissions */
