DJango memo: From the beginning (using the management screen) my addictive point

Entering Tutorial 2 from this time http://www.djangoproject.jp/doc/ja/1.0/intro/tutorial02.html#intro-tutorial02

By the way, I'm not addicted to it anymore, but I dare to leave it as it was at that time.

By the way, in my environment, python is 2.7.5 and DJango is 1.6.

Use admin page

First check settings.py

settings.py ######

#this part
INSTALLED_APPS = (
     'django.contrib.admin',   #I need this. In my case it was included by default
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     'django.contrib.sites',
     'polls'
 )

If you add it again

python manage.py syncdb

Execute. It's a theory to add a database after adding an application. Then edit urls.py. I got a little troubled here.

urls.py ###### In the tutorial

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Example:
    # (r'^mysite/', include('mysite.foo.urls')),

    # Uncomment the admin/doc line below and add 'django.contrib.admindocs'
    # to INSTALLED_APPS to enable admin documentation:
    # (r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    (r'^admin/(.*)', admin.site.root),
)

Since it is described as such, for the time being, just do it

python manage.py runserver

After this, if you go to http://127.0.0.1:8000/admin/, you should see the login screen. But the result is an error. The message is

ImportError at /admin/

No module named defaults

I think it may be due to the difference in version (the tutorial assumes 1.0, but I am 1.6), so I will return to the state before editing. Actually, there was the following description before editing.

from django.conf.urls import patterns, include, url   #Import statement included by default
 
from django.contrib import admin
admin.autodiscover()
 
urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'myDj.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),   #All examples()Is preceded by a url
)

Since what I'm doing looks the same, I thought that the writing style had changed, so I started it and accessed it. But again, no. However, the error message is different.

ImproperlyConfigured at /admin/

You're using the Django "sites framework" without having set the SITE_ID setting. Create a site in your database and set the SITE_ID setting to fix this error.

I don `t really understand. It's understandable that you are told to set a site ID, but how do you do that? Even if I googled with an error message

This time I tried to write in a timely manner as a measure of bitterness.

from django.conf.urls import patterns, include, url   #Adopt the one that does not fail here

from django.contrib import admin
admin.autodiscover()
 
urlpatterns = patterns('',
    #Default notation url(r'^admin/', include(admin.site.urls))
    #Tutorial notation(r'^admin/(.*)', admin.site.root)
    url(r'^admin/(.*)', include(admin.site.root))

Then

AttributeError at /admin/

'AdminSite' object has no attribute 'root'

The above is the contents at that time.

Now it's resolved thanks to the comments (I'm glad I posted it).
