  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Como `needy` é um parâmetro obrigatório, você precisaria defini-lo na URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

In this case, **FastAPI** will notice that there is more than one body parameter in the function (there are two parameters that are Pydantic models).

So, it will then use the parameter names as keys (field names) in the body, and expect a body like:

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    },
    "user": {

...sin agregar el parámetro requerido `needy`, verás un error como:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Como `needy` es un parámetro requerido, necesitarías establecerlo en la URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

Поскольку `needy` является обязательным параметром, вам необходимо указать его в URL-адресе:
