django设置打印数据库日志

在settings.py中添加：

LOGGING = {
'disable_existing_loggers': False,
'version': 1,
'handlers': {
'console': {
# logging handler that outputs log messages to terminal
'class': 'logging.StreamHandler',
'level': 'DEBUG', # message level to be written to console
},
},
'loggers': {
'': {
# this sets root level logger to log debug and higher level
# logs to console. All other loggers inherit settings from
# root level logger.
'handlers': ['console'],
'level': 'DEBUG',
'propagate': False, # this tells logger to send logging message
# to its parent (will send if set to True)
},
'django.db': {
# # django also has database level logging
'handlers': ['console'],
'level': 'DEBUG',
'propagate': False,
},
},
}
