Prefer to use the `Annotated` version if possible.

///

```Python
commons: CommonQueryParams ...
```

////

...doesn't have any special meaning for **FastAPI**. FastAPI won't use it for data conversion, validation, etc. (as it is using the `Depends(CommonQueryParams)` for that).

You could actually write just:

//// tab | Python 3.10+

```Python
commons: Annotated[Any, Depends(CommonQueryParams)]
```

/// note | Remarque

Notez que, bien que `item` ait été déclaré de la même manière qu'auparavant, il est désormais attendu à l'intérieur du corps de la requête sous la clé `item`.

///

**FastAPI** effectuera la conversion automatique depuis la requête, de sorte que le paramètre `item` reçoive son contenu spécifique, et de même pour `user`.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.

That way, we can declare just the differences between the models (with plaintext `password`, with `hashed_password` and without password):

        QueryBuilder buildQuery(String field, String text, float boost);
    }

    /**
     * Template method that handles the common pattern of query conversion:
     * 1. Check if field is DEFAULT_FIELD and apply default query builder
     * 2. Check if field is a search field and apply field-specific query
     * 3. Fall back to default query builder for unsupported fields
     *

Это обеспечит поддержку редактора кода внутри функции (проверка ошибок, автозавершение и т.п.).
