Logging django.request to file instead of console

Question

I am trying to configure my django settings.py to properly use the python logging facility but I've stumbled upon a rather strange problem:

Even after reading the docs, I simply can't find out how to redirect the console printed debug request lines from Django to a file I've specified; Below is part of my logging configuration.

LOGGING = {
    'version': 1,
    'formatters': {
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
    }
    'handlers': {
        'file_http': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': r'C:\mysystem-http.log',
            'formatter': 'verbose'
        }
    },
    'loggers': {
        'django.request': {
            'handlers': ['file_http'],
            'level': 'DEBUG',
            'propagate': False
        }
    }
}

I keep seeing my console print line of the following format:

[19/Dec/2014 11:48:03] "POST /api/v1/ HTTP/1.1" 200 10

How may I redirect these to a file using the logging facility?

Thanks in advance

Answer 1

These outputs are handled by your HTTP server (WSGIServer from the standard library if running in dev mode).

The configuration of your settings.py has nothing to do with it.

Answer 2

manage.py runserver is not using logging system for messages like [19/Dec/2014 11:48:03] "POST /api/v1/ HTTP/1.1" 200 10. Instead of this, runserver uses sys.stderr (and sys.stdout for others messages). If you really need to redirect this to file you can override sys.stderr settings.py. Example - logging sys.stderr to file and console:

import sys

class Logger(object):
    def __init__(self):
        self.console = sys.stderr
        self.file = open("runserver.log", "a", 0)

    def write(self, msg):
        self.console.write(msg)
        self.file.write(msg)

sys.stderr = Logger()

In write method you can use logging system to handle this by LOGGING settings as well.

Update:

In Django 1.10, runserver output goes through logging: https://docs.djangoproject.com/en/dev/releases/1.10/#runserver-output-goes-through-logging
