Sie können auch Pydantic-Modelle zurückgeben (dazu später mehr).

Es gibt viele andere Objekte und Modelle, die automatisch zu JSON konvertiert werden (einschließlich ORMs usw.). Versuchen Sie, Ihre Lieblingsobjekte zu verwenden. Es ist sehr wahrscheinlich, dass sie bereits unterstützt werden.

## Zusammenfassung

* Importieren Sie `FastAPI`.
* Erstellen Sie eine `app` Instanz.

También puedes devolver modelos de Pydantic (ya verás más sobre esto más adelante).

Hay muchos objetos y modelos que pueden ser convertidos automáticamente a JSON (incluyendo ORMs, etc.). Intenta usar tus favoritos, es muy probable que ya tengan soporte.

## Repaso

* Importa `FastAPI`.
* Crea un instance de `app`.
* Escribe un **decorador de operación de path** (como `@app.get("/")`).

Você também pode devolver modelos Pydantic (você verá mais sobre isso mais tarde).

Existem muitos outros objetos e modelos que serão convertidos automaticamente para JSON (incluindo ORMs, etc). Tente usar seus favoritos, é altamente provável que já sejam compatíveis.

## Recapitulando

* Importe `FastAPI`.
* Crie uma instância do `app`.

You can also return Pydantic models (you'll see more about that later).

There are many other objects and models that will be automatically converted to JSON (including ORMs, etc). Try using your favorite ones, it's highly probable that they are already supported.

## Recap

* Import `FastAPI`.
* Create an `app` instance.

You could use any other SQL or NoSQL database library you want (in some cases called <abbr title="Object Relational Mapper, a fancy term for a library where some classes represent SQL tables and instances represent rows in those tables">"ORMs"</abbr>), FastAPI doesn't force you to use anything. 😎

As SQLModel is based on SQLAlchemy, you can easily use **any database supported** by SQLAlchemy (which makes them also supported by SQLModel), like:

FFE6          ; mapped                 ; 20A9          # 1.1  FULLWIDTH WON SIGN
FFE7          ; disallowed                             # NA   <reserved-FFE7>
FFE8          ; mapped                 ; 2502          # 1.1  HALFWIDTH FORMS LIGHT VERTICAL
FFE9          ; mapped                 ; 2190          # 1.1  HALFWIDTH LEFTWARDS ARROW
FFEA          ; mapped                 ; 2191          # 1.1  HALFWIDTH UPWARDS ARROW

请注意，大部分代码是`SQLAlchemy`的标准代码，您可以用于任何框架。FastAPI特定的代码和往常一样少。

## ORMs（对象关系映射）

**FastAPI**可与任何数据库在任何样式的库中一起与 数据库进行通信。

一种常见的模式是使用“ORM”：对象关系映射。

ORM 具有在代码和数据库表（“*关系型”）中的**对象**之间转换（“*映射*”）的工具。

使用 ORM，您通常会在 SQL 数据库中创建一个代表映射的类，该类的每个属性代表一个列，具有名称和类型。
