Django: Error: ImproperlyConfigured Module does not define a " " class

Question

ImproperlyConfigured: Middleware module "report" does not define a "ReportMiddleware" class

But I had defined this, but probably defined in wrong place, so where should I place this class file?

Answer 1

Today I had the same error. It was due to confusing (at least for me) naming scheme.

If you specify your middleware like so:

'yourapp.SomeMiddleware'

in your settings.py and put your SomeMiddleware class definition in SomeMiddleware.py in your application directiory your project will break. In this case settings.py should read:

'yourapp.SomeMiddleware.SomeMiddleware'

a better method would be to use a common yourapp/middleware.py for all middleware definitions and use it like django.contrib middlewares do, in which case your seetings.py should include:

'yourapp.middleware.SomeMiddleware'

Answer 2

You should put it within the module in the package as specified in the MIDDLEWARE_CLASSES setting.
