Sign up doesn't work out of the box

[diegovargasf]

Hello, I followed the instructions here:http://pinaxproject.com/pinax/quick_start/ mainly:
pip install virtualenv
virtualenv mysiteenv
source mysiteenv/bin/activate
pip install pinax-cli
pinax start account mysite

cd mysite
npm install
pip install -r requirements.txt
./manage.py migrate
./manage.py loaddata sites
npm run dev

And when I tried to sign up a new user, after sending the form, I received this error:
Exception Type: AttributeError at /account/signup/
Exception Value: 'AnonymousUser' object has no attribute '_meta'

Am I missing something?

[diegovargasf]

Disregard,
I just had to add: "django.contrib.auth.backends.ModelBackend" to my authentication backends

[nstephenh]

I'm fairly sure this should still be open, as its a bug that does need to be fixed with the template.

[jacobwegner]

I hit this as well on a project; I'm wondering if https://django-user-accounts.readthedocs.io/en/latest/usage.html#using-email-address-for-authentication needs to be updated to ensure that we are adding additional backends to AUTHENTICATION_BACKENDS, rather than overwriting the default setting (which has django.contrib.auth.backends.ModelBackend)
