Whenever a new request arrives, **FastAPI** will take care of:

* Calling your dependency ("dependable") function with the correct parameters.
* Get the result from your function.
* Assign that result to the parameter in your *path operation function*.

In this example, it would convert the Pydantic model to a `dict`, and the `datetime` to a `str`.
