Question

I’ve got an email address based backend I’m trying to use.

I’ve put the code in:

myapp /
  mymodule /
    backends.py

and in settings.py I’ve got

AUTHENTICATION_BACKENDS = (
    'myapp.mymodule.backends.EmailOrUsernameModelBackend',
    'django.contrib.auth.backends.ModelBackend'
)

but I get the error

Module "myapp.mymodule.backends" does not define a 
   "EmailOrUsernameModelBackend" authentication backend

What am I doing wrong?

Answer 1

Your settings.py and project layout look ok. You’ve not shown us your backends.py, so all we can do is guess why it’s not working.

It might be a typo in your backends.py or your settings. Check that the name of your backend class exactly matches EmailOrUsernameModelBackend, including capital letters.

If you’re not using the built in dev server, make sure that you’ve restarted it so that you’re not running an older version of the code.
