### Parámetros de Pydantic v1 { #pydantic-v1-parameters }

Si necesitas usar algunas de las herramientas específicas de FastAPI para parámetros como `Body`, `Query`, `Form`, etc. con modelos de Pydantic v1, puedes importarlas de `fastapi.temp_pydantic_v1_params` mientras terminas la migración a Pydantic v2:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

		t.Fatalf("Failed to create product, got error: %v", err)
	}

	var result Product2
	if err := DB.First(&result, "name = ?", "Nice").Error; err != nil {
		t.Fatalf("Failed to query product, got error: %v", err)
	}

	var resultClone Product2
	if err := DB.First(&resultClone, "name = ?", "Nice_clone").Error; err != nil {
		t.Fatalf("Failed to find cloned product, got error: %v", err)
	}

/// note | Hinweis

Dies wird seit FastAPI Version `0.115.0` unterstützt. 🤓

///

/// tip | Tipp

Diese gleiche Technik gilt für `Query`, `Cookie` und `Header`. 😎

///

## Cookies mit einem Pydantic-Modell { #cookies-with-a-pydantic-model }

* «path operations» (plural): «opérations de chemin»
* «path operation function»: «fonction de chemin»
* «path operation decorator»: «décorateur d'opération de chemin»

* «path parameter»: «paramètre de chemin»
* «query parameter»: «paramètre de requête»

* «the `Request`»: «`Request`» (keep as code identifier)
* «the `Response`»: «`Response`» (keep as code identifier)

* «deployment»: «déploiement»
* «to upgrade»: «mettre à niveau»

	}

	var result ScannerValuerStruct

	if err := DB.Find(&result, "id = ?", data.ID).Error; err != nil {
		t.Fatalf("no error should happen when query scanner, valuer struct, but got %v", err)
	}

	if result.ExampleStructPtr.Val != "value2" {
		t.Errorf(`ExampleStructPtr.Val should equal to "value2", but got %v`, result.ExampleStructPtr.Val)
	}

### Pydantic v1 parameters { #pydantic-v1-parameters }

If you need to use some of the FastAPI-specific tools for parameters like `Body`, `Query`, `Form`, etc. with Pydantic v1 models, you can import them from `fastapi.temp_pydantic_v1_params` while you finish the migration to Pydantic v2:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

	return nil
}

func (c *OperatorDNS) endpoint(bucket string, del bool) (string, error) {
	u, err := url.Parse(c.Endpoint)
	if err != nil {
		return "", err
	}
	q := u.Query()
	q.Add("bucket", bucket)
	q.Add("delete", strconv.FormatBool(del))
	u.RawQuery = q.Encode()
	return u.String(), nil
}

// Put - Adds DNS entries into operator webhook server

## Cookies com Modelos Pydantic { #cookies-with-a-pydantic-model }

Then you just do the same in your tests.

E.g.:

* To pass a *path* or *query* parameter, add it to the URL itself.
* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.
* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
