Format message arguments

Question

Closed this issue 9 years ago · 4 comments

We get messages with %s in them and an args field. Should it format the message with the provided arguments ?

logging.Formatter does

s = self._fmt % record.__dict__

agreed.

+1 This was the behaviour I expected

The actual behavior is to have the message do

message.format(fields)

Which means references to fields will have to be done as for format:

logger.warning("account {account} is in status {status}", extra={'account': 'foo', 'status': 'bar'})
