## 多個模型 { #multiple-models }

以下是模型大致長相、與其密碼欄位以及它們被使用的位置：

### 關於 `**user_in.model_dump()` { #about-user-in-model-dump }

#### Pydantic 的 `.model_dump()` { #pydantics-model-dump }

`user_in` 是一個 `UserIn` 類別的 Pydantic 模型。

Pydantic 模型有 `.model_dump()` 方法，會回傳包含該模型資料的 `dict`。

因此，若我們建立一個 Pydantic 物件 `user_in` 如：
