Ayrıca, dikkatinizi çekerim ki; **FastAPI**, `item_id` parametresinin bir yol parametresi olduğunu ve `q` parametresinin yol değil bir sorgu parametresi olduğunu fark edecek kadar beceriklidir.

## Sorgu Parametresi Tip Dönüşümü

Aşağıda görüldüğü gibi dönüştürülmek üzere `bool` tipleri de tanımlayabilirsiniz:

{* ../../docs_src/query_params/tutorial003_py310.py hl[7] *}

my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```


/// info

`**second_user_data` 意思是:

直接将`second_user_data`字典的键和值直接作为key-value参数传递，等同于：`User(id=4, name="Mary", joined="2018-11-30")`

### 编辑器支持

整个框架都被设计得易于使用且直观，所有的决定都在开发之前就在多个编辑器上进行了测试，来确保最佳的开发体验。
