Bu, tüm API'nızı oluşturmak için ana etkileşim noktası olacaktır.

### Adım 3: bir *path operation* oluşturun { #step-3-create-a-path-operation }

#### Path { #path }

Buradaki "Path", URL'in ilk `/` işaretinden başlayarak son kısmını ifade eder.

Yani, şu şekilde bir URL'de:

```
https://example.com/items/foo
```

...path şöyle olur:

```
/items/foo
```

## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` works the same way as `Query`, `Path` and `Body`, it has all the same parameters, etc.

/// note | Technical Details

# Body - Campos { #body-fields }

De la misma manera que puedes declarar validaciones adicionales y metadatos en los parámetros de las *path operation function* con `Query`, `Path` y `Body`, puedes declarar validaciones y metadatos dentro de los modelos de Pydantic usando `Field` de Pydantic.

## Importar `Field` { #import-field }

Primero, tienes que importarlo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

        Files.writeString(jcifsPropertiesPath, "jcifs.smb.client.nativeOs=FileOS");

        }
    }
