Django 2.0 removes the django.core.urlresolvers
module, which was moved to django.urls
in version 1.10. You should change any import to use django.urls instead, like this:
from django.urls import reverse
Note that Django 2.0 removes some features that previously were in django.core.urlresolvers
, so you might have to make some more changes before your code works. See the features deprecated in 1.9 for details on those additional changes.
