## Clase obsoleta `GraphQLApp` en Starlette

Versiones anteriores de Starlette incluyen la clase `GraphQLApp` para integrarlo con <a href="https://graphene-python.org/" class="external-link" target="_blank">Graphene</a>.

# yieldを持つ依存関係

FastAPIは、いくつかの<abbr title='時々"exit"、"cleanup"、"teardown"、"close"、"context managers"、 ...のように呼ばれる'>終了後の追加のステップ</abbr>を行う依存関係をサポートしています。

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | "豆知識"

`yield`は必ず一度だけ使用するようにしてください。

///

/// info | "情報"

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```

				return

			if rows, err := db.Statement.ConnPool.QueryContext(db.Statement.Context, db.Statement.SQL.String(), db.Statement.Vars...); db.AddError(err) == nil {
				gorm.Scan(rows, db, mode)
				db.AddError(rows.Close())
			}
		}
	}
}

func AfterDelete(db *gorm.DB) {
	if db.Error == nil && db.Statement.Schema != nil && !db.Statement.SkipHooks && db.Statement.Schema.AfterDelete {

        "The pipe state is invalid.", "All pipe instances are busy.", "No process is on the other end of the pipe.", "The pipe is being closed.",
        "Waiting for a process to open the other end of the pipe.", "File is a directory.", "A duplicate name exists on the network.",

    String JAR = "jar";

    * Por exemplo, `await myfile.seek(0)` irá para o início do arquivo.
    * Isso é especialmente útil se você executar `await myfile.read()` uma vez e precisar ler o conteúdo novamente.
* `close()`: Fecha o arquivo.

Como todos esses métodos são métodos `assíncronos`, você precisa "aguardar" por eles.

Por exemplo, dentro de uma função de *operação de rota* `assíncrona`, você pode obter o conteúdo com:

```Python

					dest := db.Statement.Dest
					db.Statement.Dest = db.Statement.ReflectValue.Addr().Interface()
					gorm.Scan(rows, db, mode)
					db.Statement.Dest = dest
					db.AddError(rows.Close())
				}
			} else {
				result, err := db.Statement.ConnPool.ExecContext(db.Statement.Context, db.Statement.SQL.String(), db.Statement.Vars...)

				if db.AddError(err) == nil {

		return
	}

	resp, err := target.Send(eventData)
	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}
	defer resp.Body.Close()

	if eventData.GetObjectContext.OutputRoute != resp.Header.Get(xhttp.AmzRequestRoute) {
		tokenErr := errorCodes.ToAPIErr(ErrInvalidRequest)
		tokenErr.Description = "The request route included in the request is invalid"
