# Query Parameters

When you declare other function parameters that are not part of the path parameters, they are automatically interpreted as "query" parameters.

```Python hl_lines="9"
{!../../docs_src/query_params/tutorial001.py!}
```

The query is the set of key-value pairs that go after the `?` in a URL, separated by `&` characters.

For example, in the URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

## Use the model

Inside of the function, you can access all the attributes of the model object directly:

## Request body + path parameters

You can declare path parameters and request body at the same time.

New function [Comparable] returns the hash of comparable value v.

Como as dependências também serão chamadas pelo **FastAPI** (da mesma forma que *funções de operação de rota*), as mesmas regras se aplicam ao definir suas funções.

Você pode utilizar `async def` ou apenas `def`.

E você pode declarar dependências utilizando `async def` dentro de *funções de operação de rota* definidas com `def`, ou declarar dependências com `def` e utilizar dentro de *funções de operação de rota* definidas com `async def`, etc.

### Custom Generate Unique ID Function

FastAPI uses a **unique ID** for each *path operation*, it is used for the **operation ID** and also for the names of any needed custom models, for requests or responses.

You can customize that function. It takes an `APIRoute` and outputs a string.
