Buradaki kritik nokta, bir dependency'nin "callable" olması gerektiğidir.

Python'da "**callable**", Python'ın bir function gibi "çağırabildiği" her şeydir.

Yani elinizde `something` adlı bir nesne varsa (function _olmak zorunda değil_) ve onu şöyle "çağırabiliyorsanız" (çalıştırabiliyorsanız):

```Python
something()
```

veya

```Python
something(some_argument, some_keyword_argument="foo")
```

	Data0A string `gorm:"index:,composite:comp_id0"`

	CompIdxLevel1C

	// Composite Index: Unique and priority.
	Data2A string `gorm:"index:,unique,composite:comp_id2,priority:2"`

    }

Mais cet exemple reste valable et montre comment interagir avec les composants internes.

該 dataclass 會自動轉換為 Pydantic 的 dataclass。

如此一來，其結構描述（schema）會顯示在 API 文件介面中：

<img src="/img/tutorial/dataclasses/image01.png">

## 巢狀資料結構中的 Dataclasses { #dataclasses-in-nested-data-structures }

你也可以將 `dataclasses` 與其他型別註記結合，建立巢狀的資料結構。

在某些情況下，你可能仍需要使用 Pydantic 版本的 `dataclasses`。例如，當自動產生的 API 文件出現錯誤時。

這種情況下，你可以把標準的 `dataclasses` 直接換成 `pydantic.dataclasses`，它是可直接替換（drop-in replacement）的：

        assertNotNull(responseString);
        assertTrue(responseString.length() > 0);
    }
