# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

## `File` und `Form` importieren { #import-file-and-form }

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

## `File` und `Form`-Parameter definieren { #define-file-and-form-parameters }

Erstellen Sie Datei- und Formularparameter, so wie Sie es auch mit `Body` oder `Query` machen würden:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

Declara los **parámetros query** que necesitas en un **modelo de Pydantic**, y luego declara el parámetro como `Query`:

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** **extraerá** los datos para **cada campo** de los **parámetros query** en el request y te proporcionará el modelo de Pydantic que definiste.

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.

So, the path parameter will be extracted, validated, converted to the specified type and annotated with OpenAPI.

## Запретить Дополнительные Query-Параметры { #forbid-extra-query-parameters }

В некоторых случаях (не особо часто встречающихся) вам может понадобиться **ограничить** query-параметры, которые вы хотите получить.

        assertEquals(Trans2FindFirst2.LIST_SIZE, next.maxDataCount, "Max data count should use LIST_SIZE");
        assertEquals((byte) 0x00, next.maxSetupCount, "Max setup count must be 0");

        // Information level defaults to BOTH_DIRECTORY_INFO (0x104) — check via parameters encoding

            Map<String, Object> parameters = new HashMap<>();
            // NOTE: These parameter names _must_ match the setter names in ReleaseNotesTransformer
            parameters.put("baseCss", getBaseCssFile().get().getAsFile());
            parameters.put("releaseNotesCss", getReleaseNotesCssFile().get().getAsFile());

* Beide _Pfade_ nehmen `GET` Operationen (auch bekannt als HTTP-_Methoden_) entgegen.
* Der _Pfad_ `/items/{item_id}` hat einen _Pfad-Parameter_ `item_id`, der ein `int` sein sollte.
* Der _Pfad_ `/items/{item_id}` hat einen optionalen `str`-_Query-Parameter_ `q`.
