How to see every activity in logs of Django 2.0.6?

[prateek gupta]

Hi Experts,

I am facing a strange issue in my Django2.0.6+Mysql application.

In my settings ,py I have set Debug=True, but in logs I am not seeing any info/warning/error.

Currently I am merging two products into one to remove duplicate products from Django admin panel but when I click on Preview button page is just refreshed; no any error in logs.

So I need to investigate the cause but unable to find since not getting any logs.

Can anyone please tell me how can enable logs here?

Thanks!

sounds like you have a misconfiguration with your logging.  post your LOGGING dict in your settings

PFB my settings-

# Reading data from the environment file

ENV_FILE_PATH = os.path.join(BASE_DIR, 'config.json')

try:

    with open(ENV_FILE_PATH) as env_file:

        ENV_TOKENS = json.load(env_file)

except IOError:

    logger = logging.getLogger(__name__)

    logger.warning('Couldn\'t find the env file! You running on '

                   'absolute dummy configurations.')

    ENV_TOKENS = {}

# SECURITY WARNING: don't run with debug turned on in production!

DEBUG = True

[Jason]

ok, so you don't even have any logging configuration at all, no wonder you don't see anything.

I suggest you look in the docs for this:  https://docs.djangoproject.com/en/2.0/topics/logging/

decent example  https://gist.github.com/ipmb/0618f44dc5270f9a2be2826d0d933ed7

I forgot to mentions, I am using logger also as below-

# send server errors to admin
ADMINS = (('admin', 'admin@example.com'),)
MANAGERS = ADMINS

# Logging configuration for production
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': '%(asctime)s [%(levelname)s] %(filename)s:%(lineno)s %(funcName)s() : %(message)s'
        },
        'simple': {
            'format': '%(asctime)s [%(levelname)s] : %(message)s'
        },
    },
    'handlers': {
        'file': {
            'level': 'ERROR',
            'class': 'logging.FileHandler',
            'filename': 'error.log',
            'formatter': 'verbose'
        },
        'mail_admins': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
            'formatter': 'simple'
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'ERROR',
            'propagate': True,
        },
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
    },
}

OK, that's helpful.  Your loggers are set to handle error and above, right?  So Django's blocked from doing any logging below that, even with DEBUG = True

[prateek gupta]

I tried with below one to include warning also but no any warning or error in logs-

LOGGING_CONFIG = None

LOGLEVEL = os.environ.get('LOGLEVEL', 'info').upper()

logging.config.dictConfig({

    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {

        'default': {
            # exact format is not important, this is the minimum information
            'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
        },
        'django.server': DEFAULT_LOGGING['formatters']['django.server'],
    },
    'handlers': {
        # console logs to stderr
        'console': {
            'class': 'logging.StreamHandler',
            'formatter': 'default',
        },
        # Add Handler for Sentry for `warning` and above
        'sentry': {
            'level': 'WARNING',
            'class': 'raven.contrib.django.raven_compat.handlers.SentryHandler',
        },
        'django.server': DEFAULT_LOGGING['handlers']['django.server'],
    },
    'loggers': {
        # default for all undefined Python modules
        '': {
            'level': 'WARNING',
            'handlers': ['console', 'sentry'],
        },
        # Our application code
        'app': {
            'level': LOGLEVEL,
            'handlers': ['console', 'sentry'],
            # Avoid double logging because of root logger
            'propagate': False,
        },
        # Prevent noisy modules from logging to Sentry
        'noisy_module': {
            'level': 'ERROR',
            'handlers': ['console'],
            'propagate': False,
        },
        # Default runserver request logging
        'django.server': DEFAULT_LOGGING['loggers']['django.server'],
    },
})

You need to add the logging config to `LOGGING` in the settings for django to pick it up.   logging.config.dictConfig   doesn't do it.

I have changes like below but does not have any affect-

import logging
# Disable Django's logging setup

[Jason]

no, I mean like this:

LOGGING = {

[prateek gupta]

then it says -

File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed

  File "E:\cms-app\ps-cms\ps_cms\settings.py", line 256, in <module>

    'django.server': DEFAULT_LOGGING['loggers']['django.server'],

TypeError: 'module' object is not callable

[prateek gupta]

I am using like below-

logging({

})

[prateek gupta]

If I use as yours then there is no any trace in logs.
