Dans ce cas **FastAPI** attendra un body semblable à :

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

au lieu de :

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

## Pour résumer

Eğer bu örneği çalıştırıp <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> sayfasına giderseniz, şöyle bir çıktı ile karşılaşırsınız:

```JSON
{"item_id":"foo"}
```

## Tip İçeren Yol Parametreleri

Значення параметра шляху `item_id` передається у функцію як аргумент `item_id`.

Якщо запустити цей приклад та перейти за посиланням <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, то отримаємо таку відповідь:

```JSON
{"item_id":"foo"}
```

## Path параметри з типами

Ви можете визначити тип параметра шляху у функції, використовуючи стандартні анотації типів Python:

The defaultValueMap.dataprop is for common columns like this:
/- - - - - - - - - - - - - - - - - - - -
map:{
    ; REGISTER_DATETIME = sysdate
    ; REGISTER_USER     = foo
    ; REGISTER_PROCESS  = bar
    ; UPDATE_DATETIME   = sysdate
    ; UPDATE_USER       = foo
    ; UPDATE_PROCESS    = bar
    ; VERSION_NO        = 0
}

		return tx.Model(&User{}).Where("id = ?", 100).Update("name", "Foo bar")
	})
	assertEqualSQL(t, `UPDATE "users" SET "name"='Foo bar',"updated_at"='2021-10-18 19:50:09.438' WHERE id = 100 AND "users"."deleted_at" IS NULL`, sql)

	// UpdateColumn
	sql = DB.ToSQL(func(tx *gorm.DB) *gorm.DB {
		return tx.Model(&User{}).Where("id = ?", 100).UpdateColumn("name", "Foo bar")
	})

Então, se você rodar este exemplo e for até <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, você verá a seguinte resposta:

```JSON
{"item_id":"foo"}
```

## Parâmetros da rota com tipos

Você pode declarar o tipo de um parâmetro na função usando as anotações padrões do Python:
