Hello Django Team, Thanks for creating such powerful framework and making
it open. For one of my projects i wanted to let users login with OTP, for
which i am doing the verification manually. I want to use the login() to
let the user login to his account, order products. For which i created my
own backend to query the model with the phone number all this part until
authenticate is working fine. but i am not able to figure out how to use
login from here. below is a snippet of what i created.
Backend:
{{{
from .models import Customer
class CustomerModelBackend(object):
def authenticate(self, phone_number=None, password=None):
try:
user = Customer.objects.get(phone=phone_number)
if user is not None:
return user
else:
return False
except user.DoesNotExist:
return False
def get_user(self, phone):
try:
return Customer.objects.get(pk=phone)
except Customer.DoesNotExist:
return None
}}}
Views.py
{{{
customer_backend = CustomerModelBackend()
customer_exist = customer_backend.authenticate(phone_number=phone)
login(request, customer_exist)
}}}
Here customer_exist is getting customer object as expected but login
function is throwing global name not defined. importing login from
contrib/auth is throwing backend not defined.
Someone please advice what to do.
Thanks.
