Maven https://maven.apache.org/ https://maven.apache.org/ Maven is a project development management and comprehension tool. Maven is a project development management and comprehension tool. Based on the concept of a project object model: builds, dependency management, documentation creation, site publication, and distribution publication are all controlled from the declarative file. Maven can be extended by plugins to utilise a number of other development tools for reporting or the build process....

そのために、これらすべてのスコープを `str` の `list` として含む `security_scopes.scopes` を使います。

## 依存関係ツリーとスコープ { #dependency-tree-and-scopes }

依存関係ツリーとスコープをもう一度見てみましょう。

`get_current_active_user` 依存関係は `get_current_user` をサブ依存として持つため、`get_current_active_user` で宣言された `"me"` スコープは、`get_current_user` に渡される `security_scopes.scopes` の必須スコープ一覧に含まれます。

### Session 依存関係の作成 { #create-a-session-dependency }

`Session` は、メモリ上でオブジェクトを保持して変更を追跡し、`engine` を使ってデータベースと通信します。

各リクエストごとに新しい `Session` を提供する、`yield` を使った FastAPI の依存関係を作成します。これにより、1 リクエストにつき 1 つのセッションを使うことが保証されます。🤓

# build is static and TensorFlow symbols (in Python only) are loaded into the

# projects building with Bazel and importing TensorFlow as a dependency will not
# depend on libtensorflow_framework.so unless they opt in.

* How to set **validation constraints** as `maximum_length` or `regex`.
* A very powerful and easy to use **<dfn title="also known as components, resources, providers, services, injectables">Dependency Injection</dfn>** system.
* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.

Claro, há alguns casos em que não há problema em executar as etapas anteriores várias vezes; nesse caso, é muito mais fácil de lidar.

/// tip | Dica

Além disso, tenha em mente que, dependendo da sua configuração, em alguns casos você **pode nem precisar de nenhuma etapa anterior** antes de iniciar sua aplicação.

Nesse caso, você não precisaria se preocupar com nada disso. 🤷

然后，我们来添加一个函数，使用 `SQLModel.metadata.create_all(engine)` 为所有*表模型***创建表**。

### 创建会话（Session）依赖项 { #create-a-session-dependency }

**`Session`** 会存储**内存中的对象**并跟踪数据中所需更改的内容，然后它**使用 `engine`** 与数据库进行通信。

我们会使用 `yield` 创建一个 FastAPI **依赖项**，为每个请求提供一个新的 `Session`。这确保我们每个请求使用一个单独的会话。🤓

然后我们创建一个 `Annotated` 的依赖项 `SessionDep` 来简化其他也会用到此依赖的代码。
