# Plantillas { #templates }

Puedes usar cualquier motor de plantillas que desees con **FastAPI**.

Una elección común es Jinja2, el mismo que usa Flask y otras herramientas.

Hay utilidades para configurarlo fácilmente que puedes usar directamente en tu aplicación de **FastAPI** (proporcionadas por Starlette).

## Instala dependencias { #install-dependencies }

Asegúrate de crear un [entorno virtual](../virtual-environments.md), activarlo e instalar `jinja2`:

dataclass는 자동으로 Pydantic dataclass로 변환됩니다.

이렇게 하면 해당 스키마가 API docs 사용자 인터페이스에 표시됩니다:

## 중첩 데이터 구조에서 Dataclasses 사용하기 { #dataclasses-in-nested-data-structures }

`dataclasses`를 다른 타입 애너테이션과 조합해 중첩 데이터 구조를 만들 수도 있습니다.

일부 경우에는 Pydantic 버전의 `dataclasses`를 사용해야 할 수도 있습니다. 예를 들어 자동 생성된 API 문서에서 오류가 발생하는 경우입니다.
