defaultList.add("keyword1");
        defaultList.add("keyword2");
        fieldLogMap.put(Constants.DEFAULT_FIELD, defaultList);
        getMockRequest().setAttribute(Constants.FIELD_LOGS, fieldLogMap);

        queryContext = new QueryContext("test", true);
        List<String> keywords = queryContext.getDefaultKeyword();
        assertEquals(2, keywords.size());

So, we get a Pydantic model from the data in another Pydantic model.

#### Unpacking a `dict` and extra keywords { #unpacking-a-dict-and-extra-keywords }

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

- AWS S3's [reserved keywords](https://docs.aws.amazon.com/AmazonS3/latest/dev/s3-glacier-select-sql-reference-keyword-list.html) list is not yet respected.

            list = new ArrayList<>();
            fieldLogMap.put(field, list);
        }
        list.add(text);
    }

    /**
     * Gets the default field keywords from the field log.
     * @return List of keywords for the default field, or empty list if none.
     */
    public List<String> getDefaultKeyword() {
        if (fieldLogMap != null) {

## Recap { #recap }

You can use Pydantic's `Field` to declare extra validations and metadata for model attributes.

...Python has a little special syntax for that.

Pass `*`, as the first parameter of the function.

Python won't do anything with that `*`, but it will know that all the following parameters should be called as keyword arguments (key-value pairs), also known as <abbr title="From: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>. Even if they don't have a default value.

{* ../../docs_src/path_params_numeric_validations/tutorial003.py hl[7] *}

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).
* Any sequence of arguments that should be passed to the task function in order (`email`).
* Any keyword arguments that should be passed to the task function (`message="some notification"`).

## Dependency Injection { #dependency-injection }

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

Before that, it only supported the keyword `example` with a single example. That is still supported by OpenAPI 3.1.0, but is deprecated and is not part of the JSON Schema standard. So you are encouraged to migrate `example` to `examples`. 🤓

- To enhance usability and developer experience, CRD validation rules now support direct use of (CEL) reserved keywords as field names in object validation expressions for existing expressions in storage, will fully support runtime in next release for compatibility concern.
