So, in our case, if we set the Peewee state variable (with a default `dict`) in the `async` dependency, all the rest of the internal code in our app will see this value and will be able to reuse it for the whole request.

And the context variable would be set again for the next request, even if they are concurrent.

### Set database state in the dependency `get_db()`

Now you can create an annotated dependency once, like this:

```Python
CurrentUser = Annotated[User, Depends(get_current_user)]
```

And then you can reuse this `Annotated` dependency:

```Python
CurrentUser = Annotated[User, Depends(get_current_user)]


@app.get("/items/")
def read_items(user: CurrentUser):
    ...

{!../../../docs_src/sql_databases/sql_app/crud.py!}
```

!!! tip
    By creating functions that are only dedicated to interacting with the database (get a user or an item) independent of your *path operation function*, you can more easily reuse them in multiple parts and also add <abbr title="Automated tests, written in code, that check if another piece of code is working correctly.">unit tests</abbr> for them.
