error when start dagobah

[nacrowei]

Hi , I have installed dagobah by gitting the source code. When I executed the dagobahd , it showed as below:

No handlers could be found for logger "dagobah"
Logging output to /opt/dagobah/logs/logging
Starting app on 10.228.152.18:9000

I can access the website and login the dagobah , but I couldn't add any jobs . I checked the source code , it just like this

def add_job(self, job_name, job_id=None):
""" Create a new, empty Job. """
logger.debug('Creating a new job named {0}'.format(job_name))
if not self._name_is_available(job_name):
raise DagobahError('name %s is not available' % job_name)

    if not job_id:
        job_id = self.backend.get_new_job_id()
        self.created_jobs += 1

    self.jobs.append(Job(self,
                         self.backend,
                         job_id,
                         job_name))

    job = self.get_job(job_name)
    job.commit()

I guess that '''No handlers could be found for logger "dagobah" ''' caused the issue . I have googled for this kind of problem, someone said that I should import the logging , but I check the source code and found it contained the sentence 'import logging' .

Is there any mistaken I have made ? Or there is no any relationship between No handlers could be found for logger "dagobah" and the "import logging"
