!!! info
    FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

    If you have an older version, you would get errors when trying to use `Annotated`.

    Make sure you [Upgrade the FastAPI version](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

## Use `Annotated` in the type for the `q` parameter

$ python ./scripts/docs.py serve

Warning: this is a very simple server. For development, use mkdocs serve instead.

#### Übersetzungsspezifische Tipps und Richtlinien

And it shows their true commitment to FastAPI and its **community** (you), as they not only want to provide you a **good learning experience** but also want to make sure you have a **good and healthy framework**, FastAPI. 🙇

You might want to try their courses:

## Using the `jsonable_encoder` in a `Response`

Because **FastAPI** doesn't do any change to a `Response` you return, you have to make sure it's contents are ready for it.

For example, you cannot put a Pydantic model in a `JSONResponse` without first converting it to a `dict` with all the data types (like `datetime`, `UUID`, etc) converted to JSON-compatible types.

For large responses, returning a `Response` directly is much faster than returning a dictionary.

This is because by default, FastAPI will inspect every item inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.

And we return the scopes as part of the JWT token.

!!! danger
    For simplicity, here we are just adding the scopes received directly to the token.

    But in your application, for security, you should make sure you only add the scopes that the user is actually able to have, or the ones you have predefined.

=== "Python 3.10+"

    ```Python hl_lines="155"
    {!> ../../../docs_src/security/tutorial005_an_py310.py!}
    ```

```Python hl_lines="24"
{!../../../docs_src/sql_databases_peewee/sql_app/database.py!}
```

!!! tip
    Make sure you overwrite `db._state` *after* creating `db`.

!!! tip
    You would do the same for any other Peewee database, including `PostgresqlDatabase`, `MySQLDatabase`, etc.

## Create the database models

                Custom operation ID to be used by this *path operation*.

                By default, it is generated automatically.

                If you provide a custom operation ID, you need to make sure it is
                unique for the whole API.

                You can customize the
                operation ID generation with the parameter
                `generate_unique_id_function` in the `FastAPI` class.

    ```

!!! tip
    By the spec, you should return a JSON with an `access_token` and a `token_type`, the same as in this example.

    This is something that you have to do yourself in your code, and make sure you use those JSON keys.

    It's almost the only thing that you have to remember to do correctly yourself, to be compliant with the specifications.

    For the rest, **FastAPI** handles it for you.
