## 단일 모델로 애플리케이션 생성하기 { #create-the-app-with-a-single-model }

우선 단일 **SQLModel** 모델을 사용하여 애플리케이션의 가장 간단한 첫 번째 버전을 생성해보겠습니다.

이후 아래에서 **여러 모델**로 보안과 유연성을 강화하며 개선하겠습니다. 🤓

### 모델 생성하기 { #create-models }

`SQLModel`을 가져오고 데이터베이스 모델을 생성합니다:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

                    toString() == "/${JarFile.MANIFEST_NAME}" && !seenManifest

                private
                fun visitClassFile(file: Path) {
                    try {
                        if (file.endsWith("module-info.class")) {
                            // We can't keep this info intact, ignore this.
                            return
                        }

# Código de Estado del Response { #response-status-code }

De la misma manera que puedes especificar un modelo de response, también puedes declarar el código de estado HTTP usado para el response con el parámetro `status_code` en cualquiera de las *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

{* ../../docs_src/response_status_code/tutorial001_py310.py hl[6] *}

/// note | Nota

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

Si cada ítem JSON que quieres enviar de vuelta es de tipo `Item` (un modelo de Pydantic) y es una función async, puedes declarar el tipo de retorno como `AsyncIterable[Item]`:

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[9:11,22] *}

## Utilidades de **FastAPI** { #fastapi-utilities }

FastAPI proporciona varias herramientas para cada uno de estos esquemas de seguridad en el módulo `fastapi.security` que simplifican el uso de estos mecanismos de seguridad.

En los siguientes capítulos verás cómo agregar seguridad a tu API usando esas herramientas proporcionadas por **FastAPI**.

Import `ServerSentEvent` from `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}

The `data` field is always encoded as JSON. You can pass any value that can be serialized as JSON, including Pydantic models.

## Raw Data { #raw-data }

If you need to send data **without** JSON encoding, use `raw_data` instead of `data`.
