// Officially, the name and comment fields are supposed to be encoded
	// in CP-437 (which is mostly compatible with ASCII), unless the UTF-8
	// flag bit is set. However, there are several problems:
	//
	//	* Many ZIP readers still do not support UTF-8.
	//	* If the UTF-8 flag is cleared, several readers simply interpret the
	//	name and comment fields as whatever the local system encoding is.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/cookie_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra cookies**, they will receive an **error** response.

        super.tearDown(testInfo);
        // Clear static fields
        clearStaticFields();
    }

    private void clearStaticFields() throws Exception {
        Field runningField = Crawler.class.getDeclaredField("running");
        runningField.setAccessible(true);
        ((AtomicBoolean) runningField.get(null)).set(false);

        Field errorsField = Crawler.class.getDeclaredField("errors");

## List alanları { #list-fields }

Bir attribute’u bir alt tipe sahip olacak şekilde tanımlayabilirsiniz. Örneğin, bir Python `list`:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Bu, `tags`’in bir list olmasını sağlar; ancak list’in elemanlarının tipini belirtmez.

## Tip parametresi olan list alanları { #list-fields-with-type-parameter }
