Sie können einen `title` hinzufügen:

{* ../../docs_src/query_params_str_validations/tutorial007_an_py310.py hl[10] *}

Und eine `description`:

{* ../../docs_src/query_params_str_validations/tutorial008_an_py310.py hl[14] *}

## Alias-Parameter { #alias-parameters }

Stellen Sie sich vor, Sie möchten, dass der Parameter `item-query` ist.

Wie in:

    "docs_src/dependencies/tutorial013_an_py310.py",  # temporary code example?
    "docs_src/dependencies/tutorial014_an_py310.py",  # temporary code example?
    # Pydantic v1 migration, no longer tested
    "docs_src/pydantic_v1_in_v2/tutorial001_an_py310.py",
    "docs_src/pydantic_v1_in_v2/tutorial001_an_py39.py",
    "docs_src/pydantic_v1_in_v2/tutorial002_an_py310.py",

{* ../../docs_src/pydantic_v1_in_v2/tutorial001_an_py310.py hl[1,4] *}

### FastAPI-Unterstützung für Pydantic v1 in v2 { #fastapi-support-for-pydantic-v1-in-v2 }

        pytest.param("tutorial002_an_py39"),
        pytest.param("tutorial002_an_py310", marks=needs_py310),
        pytest.param("tutorial003_py39"),

        pytest.param("tutorial003_an_py310", marks=needs_py310),
        pytest.param("tutorial004_py39"),

### `Body` mit `examples` { #body-with-examples }

Hier übergeben wir `examples`, welches ein einzelnes Beispiel für die in `Body()` erwarteten Daten enthält:

{* ../../docs_src/schema_extra_example/tutorial003_an_py310.py hl[22:29] *}

### Beispiel in der Dokumentations-Benutzeroberfläche { #example-in-the-docs-ui }

Mit jeder der oben genannten Methoden würde es in `/docs` so aussehen:
