Server error (500) in Django if template debug parameter is set to False?

Question

I see a Django 500 Error when I set DEBUG = False to Django. I am using Django 1.5 and Python 2.7 . I also included ALLOWED_HOSTS in my template. Here are my full settings.py:

 # Django settings for genalytics project. from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS import djcelery import os __file__ = os.getcwd() ROOT_PATH = os.path.dirname(__file__) djcelery.setup_loader() #New in Django 1.5 ALLOWED_HOSTS = ['localhost', '127.0.0.1:8000'] DEBUG = False TEMPLATE_DEBUG = DEBUG ADMINS = ( ('sachit', ' [e-mail] ') ) BROKER_TRANSPORT = "sqlalchemy" BROKER_URL = "sqla+mysql://root: password@localhost /galaxy" MANAGERS = ADMINS DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.

LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'require_debug_false': { '()': 'django.utils.log.RequireDebugFalse' } }, 'handlers': { 'mail_admins': { 'level': 'ERROR', 'filters': ['require_debug_false'], 'class': 'django.utils.log.AdminEmailHandler' } }, 'loggers': { 'django.request': { 'handlers': ['mail_admins'], 'level': 'ERROR', 'propagate': True, }, } } 

What's wrong?

The log is updated as suggested by Ryu_hayabusa, and I get this error in the console:

 Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x22e08d0>> Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/django/core/management/commands/runserver.py", line 114, in inner_run ipv6=self.use_ipv6, threading=threading) File "/usr/local/lib/python2.7/dist-packages/django/core/servers/basehttp.py", line 193, in run httpd.serve_forever() File "/usr/lib/python2.7/SocketServer.py", line 235, in serve_forever r, w, e = _eintr_retry(select.select, [self], [], [], AttributeError: 'NoneType' object has no attribute 'select' 

Answer 1

For django v 1.5+ in the settings.py file, configure ALLOWED_HOSTS = ['*'] if you want to fix it quickly

If you really want to produce (and are concerned about security), put the resolved hostnames in ALLOWED_HOSTS

Setting DEBUG = False causes a 500 error

Answer 2

Change the LOGGING settings below the code, after which you can get an error message in the console.

 LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'require_debug_false': { '()': 'django.utils.log.RequireDebugFalse' } }, 'handlers': { 'mail_admins': { 'level': 'ERROR', 'filters': ['require_debug_false'], 'class': 'django.utils.log.AdminEmailHandler' }, 'console':{ 'level': 'DEBUG', 'class': 'logging.StreamHandler', }, }, 'loggers': { 'django.request': { 'handlers': ['mail_admins'], 'level': 'ERROR', 'propagate': True, }, } } 

don't forget to set DEBUG = False

Answer 3

Go to the django administration portal.
Click on the sites table and edit example.com for your domain name.
He will work.
