Para isso, nós utilizamos `security_scopes.scopes`, que contém uma `list` com todos esses escopos como uma `str`.

## Árvore de dependência e escopos { #dependency-tree-and-scopes }

Vamos rever novamente essa árvore de dependência e os escopos.

 *   <li>Project setup, execution, and teardown phases management</li>

### Создание зависимости Session { #create-a-session-dependency }

**`Session`** хранит **объекты в памяти** и отслеживает необходимые изменения в данных, затем **использует `engine`** для общения с базой данных.

            include_in_schema=include_in_schema,
            json_schema_extra=json_schema_extra,
            **extra,
        )


@dataclass(frozen=True)
class Depends:
    dependency: Optional[Callable[..., Any]] = None
    use_cache: bool = True
    scope: Union[Literal["function", "request"], None] = None


@dataclass(frozen=True)
class Security(Depends):

### Crear una Dependencia de Session { #create-a-session-dependency }

Una **`Session`** es lo que almacena los **objetos en memoria** y lleva un seguimiento de cualquier cambio necesario en los datos, luego **usa el `engine`** para comunicarse con la base de datos.

* APIキー：
     * ヘッダー
     * クエリパラメータ
     * クッキー、等

さらに、Starletteのすべてのセキュリティ機能も含みます（**セッションCookie**を含む）。

これらは、システム、データストア、リレーショナルデータベース、NoSQLデータベースなどと簡単に統合できる再利用可能なツールとコンポーネントとして構築されています。

### 依存性の注入（Dependency Injection）

FastAPIには非常に使いやすく、非常に強力な<abbr title='also known as "components", "resources", "services", "providers"'><strong>依存性の注入</strong></abbr>システムを備えています。

* 依存関係でさえも依存関係を持つことができ、階層または **依存関係の"グラフ"** を作成することができます。

## Dependabot PRs

Dependabot will create PRs to update dependencies for several things, and those PRs all look similar, but some are way more delicate than others.

* If the PR is for a direct dependency, so, Dependabot is modifying `pyproject.toml`, **don't merge it**. 😱 Let me check it first. There's a good chance that some additional tweaks or updates are needed.

    Note over dep: Run code up to yield
    opt raise Exception
        dep -->> handler: Raise Exception
        handler -->> client: HTTP error response
    end
    dep ->> operation: Run dependency, e.g. DB session
    opt raise
        operation -->> dep: Raise Exception (e.g. HTTPException)
        opt handle
            dep -->> dep: Can catch exception, raise a new HTTPException, raise other exception

### Criar uma Dependência de Sessão { #create-a-session-dependency }

Uma **`Session`** é o que armazena os **objetos na memória** e acompanha as alterações necessárias nos dados, para então **usar o `engine`** para se comunicar com o banco de dados.
