## 依赖项树与作用域

再次查看这个依赖项树与作用域。

`get_current_active_user` 依赖项包含子依赖项 `get_current_user`，并在 `get_current_active_user`中声明了作用域 `"me"` 包含所需作用域列表 ，在 `security_scopes.scopes` 中传递给 `get_current_user`。

*路径操作*自身也声明了作用域，`"items"`，这也是 `security_scopes.scopes` 列表传递给 `get_current_user` 的。

依赖项与作用域的层级架构如下：

* *路径操作* `read_own_items` 包含：
    * 依赖项所需的作用域 `["items"]`：
    * `get_current_active_user`:
        *  依赖项函数 `get_current_active_user` 包含：

Jetzt werden wir unsere Abhängigkeiten aktualisieren.

Wir möchten den `current_user` *nur* erhalten, wenn dieser Benutzer aktiv ist.

Daher erstellen wir eine zusätzliche Abhängigkeit `get_current_active_user`, die wiederum `get_current_user` als Abhängigkeit verwendet.

Beide Abhängigkeiten geben nur dann einen HTTP-Error zurück, wenn der Benutzer nicht existiert oder inaktiv ist.

## Update the dependencies { #update-the-dependencies }

Now we are going to update our dependencies.

We want to get the `current_user` *only* if this user is active.

So, we create an additional dependency `get_current_active_user` that in turn uses `get_current_user` as a dependency.

Both of these dependencies will just return an HTTP error if the user doesn't exist, or if is inactive.

Ahora vamos a actualizar nuestras dependencias.

Queremos obtener el `current_user` *solo* si este usuario está activo.

Entonces, creamos una dependencia adicional `get_current_active_user` que a su vez utiliza `get_current_user` como dependencia.

Ambas dependencias solo devolverán un error HTTP si el usuario no existe, o si está inactivo.

Agora vamos atualizar nossas dependências.

Queremos obter o `current_user` *somente* se este usuário estiver ativo.

Portanto, criamos uma dependência adicional `get_current_active_user` que por sua vez usa `get_current_user` como dependência.

Ambas as dependências retornarão apenas um erro HTTP se o usuário não existir ou se estiver inativo.
