You can combine `dataclasses` with other type annotations in many different combinations to form complex data structures.

Check the in-code annotation tips above to see more specific details.

You can also combine `dataclasses` with other Pydantic models, inherit from them, include them in your own models, etc.

### 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] *}

			// ADR label, R. Label is in From.
			target = &a[0]
			prog.To = a[1]
			targetAddr = &prog.From
		} else {
			target = &a[1]
			prog.From = a[0]
		}
	case 3:
		if p.arch.Family == sys.PPC64 {
			// Special 3-operand jumps.
			// a[1] is a register number expressed as a constant or register value
			target = &a[2]
			prog.From = a[0]
			if a[0].Type != obj.TYPE_CONST {

     */
    int getColumnNumber();

    /**
     * Gets the identifier of the model from which the problem originated. While the general form of this identifier is
     * <code>groupId:artifactId:version</code> the returned identifier need not be complete. The identifier is derived
     * from the information that is available at the point the problem occurs and as such merely serves as a best effort

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

Если вам нужно использовать некоторые специфичные для FastAPI инструменты для параметров, такие как `Body`, `Query`, `Form` и т.п., с моделями Pydantic v1, вы можете импортировать их из `fastapi.temp_pydantic_v1_params`, пока завершаете миграцию на Pydantic v2:

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

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

Wenn Sie einige der FastAPI-spezifischen Tools für Parameter wie `Body`, `Query`, `Form`, usw. zusammen mit Pydantic‑v1‑Modellen verwenden müssen, können Sie die aus `fastapi.temp_pydantic_v1_params` importieren, während Sie die Migration zu Pydantic v2 abschließen:
