Si pasas un "callable" como dependencia en **FastAPI**, analizará los parámetros de ese "callable", y los procesará de la misma manera que los parámetros de una *path operation function*. Incluyendo sub-dependencias.

Eso también se aplica a los callables sin parámetros. Igual que sería para *path operation functions* sin parámetros.

But this guide shows you, more or less, how they are intended to be used.

///

### Using Pydantic's `exclude_unset` parameter { #using-pydantics-exclude-unset-parameter }

If you want to receive partial updates, it's very useful to use the parameter `exclude_unset` in Pydantic's model's `.model_dump()`.

Like `item.model_dump(exclude_unset=True)`.

/// info

## Additional Response with `model` { #additional-response-with-model }

You can pass to your *path operation decorators* a parameter `responses`.

It receives a `dict`: the keys are status codes for each response (like `200`), and the values are other `dict`s with the information for each of them.

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Centrémonos en los parámetros declarados:

* Aunque esta función es una dependencia ("dependable") en sí misma, también declara otra dependencia (depende de algo más).
    * Depende del `query_extractor`, y asigna el valor que devuelve al parámetro `q`.
* También declara una `last_query` cookie opcional, como un `str`.

# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓
