|

DRY helper used to emit an INFO-level log message.
|
|
|
|
Messages logged with this function are used to construct an audit trail. Log messages
|
|
should be emitted immediately after the event they correspond to has occurred and, if
|
|
applicable, after the database has been updated. These log messages use a verbose
|
|
key-value pair syntax to make it easier to extract fields when parsing the application's
|
|
logs.
|
|
|
|
This function is variadic, accepting a variable number of keyword arguments.
|
|
|
|
Arguments:
|
|
name (str): The name of the message to log. For example, 'payment_received'.
|
|
|
|
Keyword Arguments:
|
|
Indefinite. Keyword arguments are strung together as comma-separated key-value
|
|
pairs ordered alphabetically by key in the resulting log message.
|
|
|
|
Returns:
|
|
None
