In some cases you don't really need the return value of a dependency inside your *path operation function*.

Or the dependency doesn't return a value.

But you still need it to be executed/solved.

For those cases, instead of declaring a *path operation function* parameter with `Depends`, you can add a `list` of `dependencies` to the *path operation decorator*.

## Add `dependencies` to the *path operation decorator*

# path operationデコレータの依存関係

場合によっては*path operation関数*の中で依存関係の戻り値を本当に必要としないこともあります。

もしくは、依存関係が値を返さない場合もあります。

しかし、それでも実行・解決する必要があります。

このような場合、*path operation関数*のパラメータを`Depends`で宣言する代わりに、*path operation decorator*に`dependencies`の`list`を追加することができます。

##  *path operationデコレータ*への`dependencies`の追加

*path operationデコレータ*はオプショナルの引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:

# Global Dependencies

For some types of applications you might want to add dependencies to the whole application.

Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

    final List<ServiceMethod> decorators;
    final List<ServiceMethod> factories;
    final List<ServiceMethod> configurers;

    private RelevantMethods(List<ServiceMethod> decorators, List<ServiceMethod> factories, List<ServiceMethod> configurers) {
        this.decorators = decorators;
        this.factories = factories;
        this.configurers = configurers;
