Extending python log hander, getting "Level not an integer or a valid string"

I am trying to create my own log handler, which extends logging.Handler

import logging
from logging import Handler

class DBHandler(Handler,object):
    model = None
    def __init__(self, model):
        super(DBHandler, self).__init__(self)
        mod = __import__(model)
        components = name.split('.')
        for comp in components[1:]:
            mod = getattr(mod, comp)
        self.model = mod

    def emit(self,record):
        log_entry = self.model(level=record.levelname, message=record.msg)
        log_entry.save()

and this is the log config:

'search_log':{
    'level': 'INFO',
    'class': 'logger.handlers.DBHandler',
    'model': 'logger.models.SearchLog',
    'formatter': 'verbose',
     }

however I am getting the follow error, see stacktrace:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/james/virtualenv/hydrogen/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'search_log': Level not an integer or a valid string: <logger.handlers.DBHandler object at 0x2df1710>

I have been looking at the python logging source code and cannot figure out what I have done wrong

i solved the same problem with changing the level='Debug' to level=30 python 3.9.0

"Level not an integer or a valid string:'%r%' level

The problem is in this line:

super(DBHandler, self).__init__(self)

You should not be passing self in if you use super this way. You're passing in self twice, effectively, and the logging module is trying to interpret the 2nd self as a logging level.
