Si chaque élément JSON que vous voulez renvoyer est de type `Item` (un modèle Pydantic) et que c'est une fonction async, vous pouvez déclarer le type de retour comme `AsyncIterable[Item]` :

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[9:11,22] *}

但此處示例使用 `PATCH`，因為它正是為這類情境設計的。

/// note | 注意

請注意，輸入的模型依然會被驗證。

因此，如果你希望接收可以省略所有屬性的部分更新，你需要一個所有屬性皆為可選（具預設值或為 `None`）的模型。

為了區分用於更新（全部可選）與用於建立（欄位為必填）的模型，你可以參考 [額外模型](extra-models.md) 中的做法。

## 创建含有单一模型的应用 { #create-the-app-with-a-single-model }

我们先创建应用的最简单的第一个版本，只有一个 **SQLModel** 模型。

稍后我们将通过下面的**多个模型**提高其安全性和多功能性。🤓

### 创建模型 { #create-models }

导入 `SQLModel` 并创建一个数据库模型：
