!!! info "`@decorator` Info"
    That `@something` syntax in Python is called a "decorator".

    You put it on top of a function. Like a pretty decorative hat (I guess that's where the term came from).

    A "decorator" takes the function below and does something with it.

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

This part is pretty normal, most of the code is probably already familiar to you:

```Python hl_lines="9-13  36-53"
{!../../../docs_src/openapi_callbacks/tutorial001.py!}
```

## Docker-образ и Poetry

Если вы пользуетесь <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a> для управления зависимостями вашего проекта, то можете использовать многоэтапную сборку образа:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)

fastapi>=0.45.0,<0.46.0
```

that would mean that you would use the versions `0.45.0` or above, but less than `0.46.0`, for example, a version `0.45.2` would still be accepted.

If you use any other tool to manage your installations, like Poetry, Pipenv, or others, they all have a way that you can use to define specific versions for your packages.

## Available versions

cela signifierait que vous utiliseriez les versions `0.45.0` ou supérieures, mais inférieures à `0.46.0`, par exemple, une version `0.45.2` serait toujours acceptée.

Si vous utilisez un autre outil pour gérer vos installations, comme Poetry, Pipenv, ou autres, ils ont tous un moyen que vous pouvez utiliser pour définir des versions spécifiques pour vos paquets.

## Poetry의 도커 이미지

만약 여러분들이 프로젝트 의존성을 관리하기 위해 <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a>를 사용한다면, 도커의 멀티-스테이지 빌딩을 사용할 수 있습니다:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)
COPY ./pyproject.toml ./poetry.lock* /tmp/

```

o que significa que você pode usar as versões `0.45.0` ou acima, mas menor que `0.46.0`. Por exemplo, a versão `0.45.2` poderia ser aceita.

Se você usa qualquer outra ferramenta para gerenciar suas instalações, como Poetry, Pipenv ou outro, todos terão um modo que você possa usar para definir versões específicas para seus pacotes.

### Versões disponíveis

* 使用Nomad等其他工具
* 使用云服务获取容器镜像并部署它

## Docker 镜像与Poetry

如果你使用 <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a> 来管理项目的依赖项，你可以使用 Docker 多阶段构建：



```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)
COPY ./pyproject.toml ./poetry.lock* /tmp/

# (5)

Das würde bedeuten, dass Sie eine Version `0.45.0` oder höher verwenden würden, aber kleiner als `0.46.0`, beispielsweise würde eine Version `0.45.2` immer noch akzeptiert.

Wenn Sie zum Verwalten Ihrer Installationen andere Tools wie Poetry, Pipenv oder andere verwenden, sie verfügen alle über eine Möglichkeit, bestimmte Versionen für Ihre Packages zu definieren.
