For the **next request**, as we will reset that context variable again in the `async` dependency `reset_db_state()` and then create a new connection in the `get_db()` dependency, that new request will have its own database state (connection, transactions, etc).

<blockquote markdown="1">

**FastAPI** wouldn't exist if not for the previous work of others.

There have been many tools created before that have helped inspire its creation.

I have been avoiding the creation of a new framework for several years. First I tried to solve all the features covered by **FastAPI** using many different frameworks, plug-ins, and tools.

    Using these `dependencies` in the *path operation decorator* you can make sure they are executed while avoiding editor/tooling errors.

    It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

!!! info
    In this example we use invented custom headers `X-Key` and `X-Token`.

    ```

### Declare the dependency, in the "dependant"

The same way you use `Body`, `Query`, etc. with your *path operation function* parameters, use `Depends` with a new parameter:

    ```Python hl_lines="13  18"

=== "Python 3.9+"

    ```Python hl_lines="15  20"

    # can create race conditions/deadlocks if the context manager itself
    # has its own internal pool (e.g. a database connection pool)
    # to avoid this we let __exit__ run without a capacity limit
    # since we're creating a new limiter for each call, any non-zero limit
    # works (1 is arbitrary)
    exit_limiter = CapacityLimiter(1)
    try:
        yield await run_in_threadpool(cm.__enter__)
    except Exception as e:
        ok = bool(

## Créer une Issue

Vous pouvez <a href="https://github.com/tiangolo/fastapi/issues/new/choose" class="external-link" target="_blank">créer une Issue</a> dans le dépôt GitHub, par exemple pour :

* Poser une question ou s'informer sur un problème.
* Suggérer une nouvelle fonctionnalité.

Der nächste Schritt besteht darin, das Skript auszuführen, um ein neues Übersetzungsverzeichnis zu erstellen:

<div class="termy">

```console
// Verwenden Sie das Kommando new-lang und fügen Sie den Sprach-Code als Argument hinten an
$ python ./scripts/docs.py new-lang ht

Successfully initialized: docs/ht
```

</div>

Jetzt können Sie in Ihrem Code-Editor das neu erstellte Verzeichnis `docs/ht/` sehen.

    new_config_docs_path: Path = new_path / "docs"
    new_config_docs_path.mkdir()
    en_index_path: Path = en_docs_path / "docs" / "index.md"
    new_index_path: Path = new_config_docs_path / "index.md"
    en_index_content = en_index_path.read_text(encoding="utf-8")
    new_index_content = f"{missing_translation_snippet}\n\n{en_index_content}"
    new_index_path.write_text(new_index_content, encoding="utf-8")

                    new_title = first_child.title or new_title
            # Creating a new section makes it render it collapsed by default
            # no idea why, so, let's just modify the existing one
            # new_section = Section(title=new_title, children=new_children)
            item.title = new_title
            item.children = new_children
            new_items.append(item)
