Make RichHandler display context variables

[Siponek]

Hello,

I would like to log context variables when logging messages. An example (without rich) would be to add new keys to json object logging via filter and somehow json logger prints out the whole object.
Example of context filter that adds attributes to json object:

if isinstance(context, dict):
    # Add the context variables to the log record
    for key, value in context.items():
        if not hasattr(record, key):
            # Add individual context variables as attributes
            setattr(record, key, value)

But when doing that with rich it does not print these variables that are added as attributes. Right now I could only "append" them to the message field, but that really defeats the purpose of structured logging.

logging_config = {
    "version": 1,
    "disable_existing_loggers": False,
    "formatters": {

        "json": {
            "()": "pythonjsonlogger.json.JsonFormatter",
            "format": """
                    %(asctime)s
                    %(created)f
                    %(filename)s
                    %(lineno)d
                    %(funcName)s
                    %(levelname)s
                    %(message)s
                """,
            "datefmt": "%Y-%m-%d %H:%M:%S",
        },
        "rich": {
            "format": "%(message)s",
            ### Is there a way to make the rich handle the secondary arguments and create a structured log?
        },
    },
    "filters": {
        "enhanced_context_filter": {
            "()": ContextFilter,
        },
    },
    "handlers": {
        "json": {
            "formatter": "json",
            "class": "logging.StreamHandler",
            "stream": stream,
        },
        "rich": {
            "class": "rich.logging.RichHandler",
            "formatter": "rich",
            "markup": True,
            "show_time": True,
            "show_path": True,
            "enable_link_path": False,
            # "rich_tracebacks": True,
            "filters": ["enhanced_context_filter"],
        },
    },
}

logging.config.dictConfig(logging_config)

Maybe this was answered before therefore let me know so I will close the discussion, but couldn't find anything. Thank you all for you input.
Here is an example with the context vars put into "message" field, but I would rather make the richHandler to print them but keep them in some different field.
