* Changes secret, configMap, downwardAPI and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will preserve the old behavior. ([#58720](https://github.com/kubernetes/kubernetes/pull/58720),...

但是在 ORM 模式下，由于 Pydantic 本身会尝试从属性访问它需要的数据（而不是假设为 `dict`），你可以声明你想要返回的特定数据，它甚至可以从 ORM 中获取它。

## CRUD工具

现在让我们看看文件`sql_app/crud.py`。

在这个文件中，我们将编写可重用的函数用来与数据库中的数据进行交互。

**CRUD**分别为：增加（**C**reate）、查询（**R**ead）、更改（**U**pdate）、删除（**D**elete），即增删改查。

...虽然在这个例子中我们只是新增和查询。

### 读取数据

从 `sqlalchemy.orm`中导入`Session`，这将允许您声明`db`参数的类型，并在您的函数中进行更好的类型检查和完成。

导入之前的`models`（SQLAlchemy 模型）和`schemas`（Pydantic*模型*/模式）。

# 並行処理と async / await

*path operation 関数*のための `async def` に関する詳細と非同期 (asynchronous) コード、並行処理 (Concurrency)、そして、並列処理 (Parallelism) の背景について。

次のような、`await` を使用して呼び出すべきサードパーティライブラリを使用している場合:

```Python
results = await some_library()
```

以下の様に `async def` を使用して*path operation 関数*を宣言します。

```Python hl_lines="2"

Performing blind upgrades in production environments carries significant risk. - Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily. - If...
