## 审查所有文件

最后回顾整个案例，您应该有一个名为的目录`my_super_project`，其中包含一个名为`sql_app`。

`sql_app`中应该有以下文件：

* `sql_app/__init__.py`：这是一个空文件。

* `sql_app/database.py`：

```Python
{!../../../docs_src/sql_databases/sql_app/database.py!}
```

* `sql_app/models.py`:

```Python
{!../../../docs_src/sql_databases/sql_app/models.py!}
```

* `sql_app/schemas.py`:

=== "Python 3.10+"

    ```Python

    Это и есть "**декоратор операции пути**".

Можно также использовать операции:

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

И более экзотические:

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

!!! tip "Подсказка"
    Вы можете использовать каждую операцию (HTTP-метод) по своему усмотрению.

    Dies ist der „**Pfadoperation-Dekorator**“.

Sie können auch die anderen Operationen verwenden:

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

Oder die exotischeren:

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

!!! tip "Tipp"
    Es steht Ihnen frei, jede Operation (HTTP-Methode) so zu verwenden, wie Sie es möchten.

@app.get("/by-alias/dict", response_model=Model)
def by_alias_dict():
    return {"alias": "Foo"}


@app.get("/by-alias/model", response_model=Model)
def by_alias_model():
    return Model(alias="Foo")


@app.get("/by-alias/list", response_model=List[Model])
def by_alias_list():
    return [{"alias": "Foo"}, {"alias": "Bar"}]


@app.get("/no-alias/dict", response_model=ModelNoAlias)

    It is the "**path operation decorator**".

You can also use the other operations:

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

And the more exotic ones:

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

!!! tip
    You are free to use each operation (HTTP method) as you wish.

    これが「*パスオペレーションデコレータ*」です。

他のオペレーションも使用できます:

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

また、よりエキゾチックなものも使用できます:

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

!!! tip "豆知識"
    各オペレーション (HTTPメソッド)は自由に使用できます。

    **FastAPI**は特定の意味づけを強制しません。

You can see those schemas because they were declared with the models in the app.

That information is available in the app's **OpenAPI schema**, and then shown in the API docs (by Swagger UI).

And that same information from the models that is included in OpenAPI is what can be used to **generate the client code**.

### Generate a TypeScript Client

Now that we have the app with the models, we can generate the client code for the frontend.

<summary>Informazioni sul comando <code>uvicorn main:app --reload</code>...</summary>

Vediamo il comando `uvicorn main:app` in dettaglio:

* `main`: il file `main.py` (il "modulo" Python).
* `app`: l'oggetto creato dentro `main.py` con la riga di codice `app = FastAPI()`.

## Przykład

### Stwórz

* Utwórz plik o nazwie `main.py` z:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
