How to solve a problem with Django admin?

Question

Django

AttributeError at /admin/ 'module' object has no attribute 'rindex'
The problem occurs only when trying to go to the admin page 127.0.0.1:8000/admin/
I can’t say for sure after what the problem appeared, but I noticed after I added a new module .

Answer 1

from django.conf.urls import include, url
from birthday.views import *

urlpatterns = [
    url(r'^', bthd, name="bthd"),
]

bthd is the name of the view?
A similar problem is described on SOF
And it is related to the incorrect indication of the view name in urls.py. Recheck for yourself.
