Simple

import logging
from slack_logger import SlackHandler, SlackFormatter

sh = SlackHandler('YOUR_WEB_HOOK_URL') # url is like 'https://hooks.slack.com/...'
sh.setFormatter(SlackFormatter())
logging.basicConfig(handlers=[sh])
logging.warning('warn message')

Using logger

import logging
from slack_logger import SlackHandler, SlackFormatter

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)

sh = SlackHandler(username='logger', icon_emoji=':robot_face:', url='YOUR_WEB_HOOK_URL')
sh.setLevel(logging.DEBUG)

f = SlackFormatter()
sh.setFormatter(f)
logger.addHandler(sh)

logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.critical('critical message')

Using filter

You can also filter some messages only

from slack_logger import SlackLogFilter

sf = SlackLogFilter()
sh.addFilter(sf)

logger.info('info message')  # Not posted to slack
logger.info('info message to slack', extra={'notify_slack': True})  # Posted to slack

Mentioning someone

Use mention option to send message with mentioning someone:

sh = SlackHandler('YOUR_WEB_HOOK_URL', mention='U012ABC34')

You can find a member ID (e.g., U012ABC34) from user’s profile view.
