Django, upgrading to 1.9 - django

Question

I evolve my Django version to 1.9 (before I had the 1.6 or 1.7), so I modify many obseltes things...
But I have a problem with theses lines in my urls.py :
import django
import main_app
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView, ListView
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from main_app.views import *
from main_app.views import password_reset_confirm
... # many urls
url(r'^authentification/$', django.contrib.auth.views.login),
url(r'^forget/send/$', django.contrib.auth.views.password_reset_done),
url(r'^password/$', django.contrib.auth.views.password_reset),
url(r'^password_forget/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$', main_app.views.password_reset_confirm),
url(r'^password-init/$', django.contrib.auth.views.password_reset_complete),
I have this error when I write "python manage.py runserver" :
Unhandled exception in thread started by <function wrapper at 0x7f5bcf01af50>
Traceback (most recent call last):

url(r'^authentification/$', django.contrib.auth.views.login),
NameError: name 'django' is not defined
I don't understand why I have a problem just with those 5 urls ??!
Thank's

Answer 1

That code doesn't show you importing django: it shows you importing elements underneath it, but never the name itself. It is a fundamental principle of Python that you must import or define every name you use. In your case, import django at the top would work, although note you would then have another problem when the code gets to the password_reset URL since that is referenced from main_app which you again haven't imported.

Answer 2

Try to create a new project with django-admin startproject and copy over the needed settings / copy over manage.py and wsgi.py.
Some releases had breaking changes, i.e. on how the wsgi module imports certain django stuff. Most projects can easy be recreated and you have the newest django defaults in the files.
It's of course just a guess, but worth trying. If you're using a virtualenv, you may need to recreate some things inside, when your python was upgraded / you moved the virtualenv. Such stuff can be quite annoying sometimes.

Resolved !
Euh I think...
Just I add these lines :
from django.contrib.auth.views import login
from django.contrib import auth
And it's works !
It's normal hein ?
