Problem at activating the admin site (Django tutorial part 2)

[pasztilla]

Hi there,
I'm just trying to accomodate myself with Django - and so I tried to
go through the Django Tutorial from the Django official site. There
went everything ok with part 1, but at the very beginning of the part
2 I've met a problem(https://docs.djangoproject.com/en/1.3/intro/
tutorial02). In spite of that I've perform all settings/changes
described in the 'Activate the admin site' section going to the next
section 'Start the development server' (ie. 127.0.0.1:8000/admin/) led
merely to an error message:

"DoesNotExist at /admin/
Site matching query does not exist.
Request Method:

So, does anybody have an idea what could be wrong? Thanks for your
attention and help(eventually) in advance!
Yours sincerelly,

In ur urls.py,
Did u import admin, make it discoverable, and also uncomment the /
admin/ url?
Also, make sure that you syncdb by running python manage.py syncdb.
Lemme know if that helps :)

[Babatunde Akinyanmi]

Please say exactly what you did. It will be easier to help that way

The error you stated normally happens when there are problems with the
django_site table created when you start a project.

[Pászkán Attila]

Yes, all these actions (*) I have done already, but they didn't help... :-(

(*): in .../mysite/urls.py I have uncommented:

         from django.contrib import admin
         admin.autodiscover()
 
         and further among urlpatterns I've uncommented:
         url(r'^admin/', include(admin.site.urls)),

     in .../mysite/settings.py:
 
         among INSTALLED_APPS I've uncommented the line containing:
         'django.contrib.admin'

     then performed: >python manage.py syncdb

   PA

then performed: >python manage.py syncdb

Can you give more details?

[Babatunde Akinyanmi]

Hi paszkan,
First I want you to go to your settings file and tell me what value is
specified for SITE_ID. You will need that value for the next step.

In your terminal where you would have typed "python manage.py
runserver" type "python manage.py shell"

Doing that would load django's inbuilt shell.

Next type:
"from django.contrib.sites.models import Site"
If there's no error type this is where you would need the SITE_ID
setting value. Assuming SITE_ID value is 1 then type:
"Site.objects.get(id=1)"

Do this and give feed back

[pasztilla]

Hi Babatunde,

Hi Babatunde,



SITE_ID == 1



then I did what you've suggested:(see the result)

!!!! +++++ !!!!

Meanwhile came an idea that this error could have slyly,
somehow undercover, something to do with my User Name (under Windows)
which contains some unusual characters (two á-s, see above) ...
I've set up a new user (without unusual characters)
and repeated the whole procedure (building up an application
according to the tutorial) and it worked fine!!! :-)


So, seemingly the problem has been resolved! :-)
(It would be interesting to find out why and how
has influenced that unusual user name the functioning
of my admin-site...but it is maybee to much effort to investigate)

Anyway, thanks for your efforts and support!

Cool. I'm really interested in finding out what went wrong. If you are
also, try to recreate the problem by using you former username and see
if the problem persists. If it does, its a bug that the community
could consider fixing. That error was thrown by the Site app so I'm
still wondering how a change in user name was able to solve it

[pasztilla]

Hi Babatunde,

1. sorry for the delayed answer - but I was in the last three weeks
far from any possibility to use the Internet (and Django as well)...
2. I have tried to reproduce the phenomenon and with the 'Pászkán
Attila' as user it worked ! Why? - still it isn't clear.

It isn't clear to me also. Initially I was surprised because the site
app doesn't have any dependency on django's user system. Even if it
does, django uses unicode which caters for those characters in your
name.
Well.....at least we are sure the problem wsnt from the user name. But
something definetely went wrong. Don't worry about it though

[Ravi Shakya]

I am also facing the exact problem indicated by pasztilla.
My usernaleme thing is fine (normal) but I have not been able to fix this issue.
Any concrete cause/solution to this?

[Karen Tracey]

Have you followed the tutorial exactly? I was unable to recreate this problem when someone opened a trac ticket describing it:

https://code.djangoproject.com/ticket/18308

Another Django dev noted it was a duplicate of another ticket:

https://code.djangoproject.com/ticket/18226

where the problem seemed to be due to adding south as an app in the tutorial rather than following the tutorial exactly.
