    连接 PostgreSQL 等数据库时，需要修改 `DATABASE_URL`。

## 创建表

本例中，使用 Python 文件创建表，但在生产环境中，应使用集成迁移等功能的 Alembic 创建表。

本例在启动 **FastAPI** 应用前，直接执行这些操作。

* 创建 `engine`
* 使用 `metadata` 对象创建所有表

```Python hl_lines="25-28"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

## 创建模型

创建以下 Pydantic 模型：

* 创建笔记的模型（`NoteIn`）
* 返回笔记的模型（`Note`）

```Python hl_lines="31-33  36-39"

        }
    }

    private boolean isSpecificVersion(String version) {
        return !((version == null || version.isEmpty()) || version.startsWith("[") || version.startsWith("("));
    }

    // TODO !![jc; 28-jul-2005] check this; if we're using '-r' and there are aggregator tasks, this will result in
    // weirdness.
    public MavenProject getTopLevelProject() {
        return sortedProjects.stream()

Here, this section would run directly, right before starting your **FastAPI** application.

* Create an `engine`.
* Create all the tables from the `metadata` object.

```Python hl_lines="25-28"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

## Create models

Create Pydantic models for:

* Notes to be created (`NoteIn`).
* Notes to be returned (`Note`).

그리고 이 수천 개의 *경로 작동*은 모두 3줄 정도로 줄일 수 있습니다.

=== "파이썬 3.7 이상"

    ```Python hl_lines="30-32"

=== "파이썬 3.10 이상"

    ```Python hl_lines="28-30"
    {!> ../../../docs_src/security/tutorial002_py310.py!}
    ```

## 요약

이제 *경로 작동 함수*에서 현재 사용자를 직접 가져올 수 있습니다.

우리는 이미 이들 사이에 있습니다.
