- DRA device taint eviction: the controller might have reported "1 pod needs to be evicted in 1 namespace. 1 pod evicted since starting the controller." when only a single pod is involved, depending on timing (pod evicted, informer cache not updated yet). It would eventually arrive at the correct "1 pod evicted since starting the controller.", but now it tries harder to avoid the confusing intermediate state by delaying the status update after eviction.

    val response = call.execute()
    assertThat(response.body.string()).isEqualTo("ABC")
    assertThat(response.protocol).isEqualTo(protocol)

    // Confirm a single ping was sent and received, and its reply was sent and received.

首先，确保你创建并激活了[虚拟环境](../virtual-environments.md)，然后安装 `sqlmodel`：

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## 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：

				<executions>
