You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/request_form_models/tutorial002_an_py310.py hl[12] *}

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

Alerting with prometheus is two step process. First we setup alerts in Prometheus server and then we need to send alerts to the AlertManager.
