title: Django logging creates an empty file
body: <p>I'm trying to use <code>Django Logging</code> so I followed some tutorials but it doesn"t seem to work, the file is created but it's empty.
  Here is my code :</p>
  
  <pre><code>LOGGING = {
      'version': 1,
      'disable_existing_loggers': False,
      'formatters': {
          'verbose': {
              'format' : "[%(asctime)s] %(levelname)s [%(name)s:%(lineno)s] %(message)s",
              'datefmt' : "%d/%b/%Y %H:%M:%S"
          },
          'simple': {
              'format': '%(levelname)s %(message)s'
          },
      },
      'handlers': {
          'file': {
              'level': 'INFO',
              'class': 'logging.FileHandler',
              'filename': 'LogFile.log',
              'formatter': 'verbose'
          },
      },
      'loggers': {
          'django': {
              'handlers':['file'],
              'propagate': True,
              'level':'DEBUG',
          },
          'app': {
              'handlers': ['file'],
              'level': 'DEBUG',
          },
  }
  }
  </code></pre>
  
  <p>and in the view :</p>
  
  <pre><code>import logging
  logger = logging.getLogger(__name__)
  
  def myfunction():
      logger.info("this is a debug message!")
  </code></pre>
