I have installed django-structlog 1.4.1 for my Django project. I have followed all the steps which has been described in that link.
In my settings.py file:
import structlog
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django_structlog.middlewares.RequestMiddleware',
]
LOGGING = {

}
}
structlog.configure(
processors=[
structlog.stdlib.filter_by_level,
structlog.processors.TimeStamper(fmt="iso"),
structlog.stdlib.add_logger_name,
structlog.stdlib.add_log_level,
structlog.stdlib.PositionalArgumentsFormatter(),
structlog.processors.StackInfoRenderer(),
structlog.processors.format_exc_info,

],
context_class=structlog.threadlocal.wrap_dict(dict),
logger_factory=structlog.stdlib.LoggerFactory(),
wrapper_class=structlog.stdlib.BoundLogger,
cache_logger_on_first_use=True,
)
In my views.py:
from django.http.response import HttpResponse
import structlog
logger = structlog.get_logger(__name__)
def func(request):
logger.debug("debug message", bar="Buz")
logger.info("info message", bar="Buz")
logger.warning("warning message", bar="Buz")
logger.error("error message", bar="Buz")
logger.critical("critical message", bar="Buz")
return HttpResponse('success')
Output in json.log:

My issues are:
- 'info' and 'debug' level log message is not showing at the console.
- Any type of log message is not writing at the log files except "event='request_started'" and "event='request_finished'"
I want same message in all of my log files and console. How can i achieve this?
