Using it led to the creation of several Flask full-stack generators. These are the main stacks I (and several external teams) have been using up to now:

Usando essa combinação levou a criação de vários geradores Flask _full-stack_. Há muitas _stacks_ que eu (e vários times externos) estou utilizando até agora:

* <a href="https://github.com/tiangolo/full-stack" class="external-link" target="_blank">https://github.com/tiangolo/full-stack</a>

    ```Python hl_lines="13  15  22  25"
    {!> ../../../docs_src/background_tasks/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="13  15  22  25"
    {!> ../../../docs_src/background_tasks/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="14  16  23  26"
    {!> ../../../docs_src/background_tasks/tutorial002_an.py!}
    ```

=== "Python 3.10+ nicht annotiert"

```Python hl_lines="6-9"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

## Adicionar a tarefa em segundo plano

Dentro de sua _função de operação de caminho_, passe sua função de tarefa para o objeto _tarefas em segundo plano_ com o método `.add_task()`:

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` recebe como argumentos:

- <a href="https://github.com/tiangolo/full-stack-flask-couchdb" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-flask-couchdb</a>

Ces mêmes générateurs full-stack ont servi de base aux [Générateurs de projets pour **FastAPI**](project-generation.md){.internal-link target=\_blank}.

        self.http_connection_param_name = http_connection_param_name
        self.response_param_name = response_param_name
        self.background_tasks_param_name = background_tasks_param_name
        self.security_scopes = security_scopes
        self.security_scopes_param_name = security_scopes_param_name
        self.name = name
        self.call = call
        self.use_cache = use_cache

!!! tip
    There is an official project generator with **FastAPI** and **Couchbase**, all based on **Docker**, including a frontend and more tools: <a href="https://github.com/tiangolo/full-stack-fastapi-couchbase" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-fastapi-couchbase</a>

## Import Couchbase components

For now, don't pay attention to the rest, only the imports:
