사실, FastAPI는 내부적으로 이 두 데코레이터를 사용합니다.

///

## `yield`를 사용하는 데이터베이스 의존성

예를 들어, 이 기능을 사용하면 데이터베이스 세션을 생성하고 작업이 끝난 후에 세션을 종료할 수 있습니다.

응답을 생성하기 전에는 `yield`문을 포함하여 그 이전의 코드만이 실행됩니다:

{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

yield된 값은 *경로 작업* 및 다른 의존성들에 주입되는 값 입니다:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

`yield`문 다음의 코드는 응답을 생성한 후 보내기 전에 실행됩니다:

        FacetInfo facetInfo = searchRequestParams.createFacetInfo(request);
        assertNotNull(facetInfo);
        assertEquals(2, facetInfo.field.length);
        assertEquals("field1", facetInfo.field[0]);
        assertEquals("field2", facetInfo.field[1]);
        assertEquals(2, facetInfo.query.length);
        assertEquals("query1", facetInfo.query[0]);
        assertEquals("query2", facetInfo.query[1]);

			field.IgnoreMigration = true
		case "migration":
			field.IgnoreMigration = true
		}
	}

	if v, ok := field.TagSettings["->"]; ok {
		field.Creatable = false
		field.Updatable = false
		if strings.ToLower(v) == "false" {
			field.Readable = false
		} else {
			field.Readable = true
		}
	}

	if v, ok := field.TagSettings["<-"]; ok {
		field.Creatable = true
		field.Updatable = true

        BooleanQuery.Builder boolQueryBuilder = new BooleanQuery.Builder();
        TermQuery termQuery1 = new TermQuery(new Term("field1", "value1"));
        TermQuery termQuery2 = new TermQuery(new Term("field2", "value2"));
        TermQuery termQuery3 = new TermQuery(new Term("field3", "value3"));

        boolQueryBuilder.add(termQuery1, BooleanClause.Occur.MUST);

   **FastAPI** использует их "под капотом" с этой целью.

## Зависимости с `yield` и `HTTPException`

Вы видели, что можно использовать зависимости с `yield` совместно с блоком `try`, отлавливающие исключения.

Таким же образом вы можете поднять исключение `HTTPException` или что-то подобное в завершающем коде, после `yield`.

# Abhängigkeiten mit yield

FastAPI unterstützt Abhängigkeiten, die nach Abschluss einige <abbr title="Manchmal auch genannt „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontext Manager Exit Code“, usw.">zusätzliche Schritte ausführen</abbr>.

Verwenden Sie dazu `yield` statt `return` und schreiben Sie die zusätzlichen Schritte / den zusätzlichen Code danach.

/// tip | Tipp

Stellen Sie sicher, dass Sie `yield` nur einmal pro Abhängigkeit verwenden.

# Dependencies with yield { #dependencies-with-yield }

FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.
