Question

I just deployed a website using Google App Engine that I built using Django. However, whenever I try to view my site live, I get a 500 error, and when I go into the App Engine dashboard and check the logs, I see the error:

"ImproperlyConfigured: Middleware module "autoload.middleware" does 
not define a "AutoloadMiddelware" class"

But this doesn’t quite make sense as I checked the autoload folder in my project and inside, there is a middeware.py file that indeed defines an AutoloadMiddleware class as follows:

from django.utils.importlib import import_module
from django.conf import settings

# load all models.py to ensure signal handling installation or index loading
# of some apps 
for app in settings.INSTALLED_APPS:
    try:
        import_module('%s.models' % (app))
    except ImportError:
        pass

class AutoloadMiddleware(object):
    """Empty because the import above already does everything for us"""
    pass

Is there something wrong with the import, perhaps? Is it possible my deployment didn’t upload the necessary django modules in addition to those in my project folder?

Answer 1

Make sure you add it to your settings.py

MIDDLEWARE_CLASSES = (
    # This loads the index definitions, so it has to come first
    'autoload.middleware.AutoloadMiddleware',

    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
)
