how to log a file in Django

Question

I have this function in views.py ( related to contact form). I need to log all the inputs and output to a temporary file, but I don't know how to do it in django. A new error appears : No handlers could be found for logger "farah"

Settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'farah': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': '/home/farah/update/farah.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['farah'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

The function in views.py : logger = logging.getLogger('farah') def contact(request):

form = FeedbackForm(request.POST or None)
   
    
if form.is_valid():
        
        recaptcha_response = request.POST.get('g-recaptcha-response')
        url = 'https://www.google.com/recaptcha/api/siteverify'
        values = {
            'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
            'response': recaptcha_response
        }
        data = urllib.urlencode(values).encode()
        req =  urllib2.Request(url, data=data)
        response = urllib2.urlopen(req)
        result = json.loads(response.read().decode())
        ''' End reCAPTCHA validation '''

        if result['success']:
    form.save()
    message = u'You have feedback\nName: %s\nEmail: %s\nPhone: %s\nCountry: %s\nFeedback:\n%s' % (
        self.cleaned_data.get['name'],
        self.cleaned_data.get['email'],
        self.cleaned_data.get['phone'],
        self.cleaned_data.get['country'],
        self.cleaned_data.get['feedback'])
    try:
        send_mail('NEW FEEDBACK', message, '', settings.DEFAULT_FROM_EMAIL) # to admin
        send_mail('THANK YOU for contacting us', 'We will be back to you promptly.', '', [self.cleaned_data.get['email'],]) # to user
        messages.info(request, 'SUCCESS! Your message has been sent!')
        form = FeedbackForm()
    except:
        messages.info(request, 'Sorry, can\'t send feedback right now.')
        else:
            messages.error(request, 'Invalid reCAPTCHA. Please try again.')

     
    else:
      form = FeedbackForm()
      logger.error('Log whatever you want') 
        
    

return render(request, 'contact.html', {'active_page':'contact','form': form,})

I viewed this page on google, but I don't know how to do it :

Add logging configurations in settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': '/path/to/django/debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

In views.py add the following code:

import logging
logger = logging.getLogger(__name__)
def contact(request):
    ...
    logger.debug('Log whatever you want')
    # It will be logged in '/path/to/django/debug.log' the path you have specified in settings.py logging conf
