Django how to print data when using runserver

I have a dictionary data with how many players every user created:

views.py

def statistics(request):
    users = User.objects.all()
    data = dict()
    for user in users:
        players = Players.objects.filter(created__email=user.email).count()
        if players > 0:
            data[user.email] = players
            logger.info(data)

How can i print this dictionary in the console when i use runserver? I have seen django loggers but i didn't understand them fully.

Just add print(players) in loop and it will print results in terminal.

def statistics(request):
users = User.objects.all()
data = dict()
for user in users:
    players = Players.objects.filter(created__email=user.email).count()
    if players > 0:
        print(players)
        data[user.email] = players
        logger.info(data)

Setup logging in your django settings file:

import os

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
            'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'),
        },
    },
}

Then you can start logging in your view:

import logging
logger = logging.getLogger(__name__)

# Put the logging info within your django view
logger.info("Simple info")

See more information on the Logging | Django Documentation

Good Luck !

You should do like

import os

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_true': {
            '()': 'django.utils.log.RequireDebugTrue',
        },
    },
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
            'filters': ['require_debug_true'],
        },
    },
    'loggers': {
        'mylogger': {
            'handlers': ['console'],
            'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'),
            'propagate': True,
        },
    },
}

This will be printing to console when DEBUG = True (normally use runserver). Then you can do

import logging
logger = logging.getLogger("mylogger")
logger.info("Whatever to log")

Assuming your project is running on linux, it depends if runserver is on nohup. If not then all print statements will be visible on command line otherwise if its running on nohup then run the below command on command line.

tail -f nohup.out

As @Andriy say you can use logging. It's get working out of the box. If you want to pretty print dictionary you can use pprint

import pprint
pp = pprint.PrettyPrinter(indent=4)

pp.pprint(yourdict)
