I've read the old posts with the same title. But the answers are not for my simple case.... But I need your help to be able to move on.
I just installed django 1.8.1, followed the tutorial to the first time hitting url http://localhost:8000/admin
I did have 'django.contrib.admin' in my settings.py, INSTALLED_APPS list. Beside that, I haven't done anything about admin.
So what's the problem? how to verify my installation? Thanks a lot for your help!
(It's ok for the home page http://localhost:8000)

If django.contrib.sites is in your list of installed apps, then you need SITE_ID in your settings file. Adding SITE_ID = 1 to settings.py should do the trick.
Maybe domain name in table django_site not equal your current domain http://localhost:8000.
You need to open dango_site db table and change in first record in field domain value to localhost:8000
I had this issue too and as Mikhail suggested, I had a look in django_site db table, and there was an entry with a domain named example.com.
You could change that record to localhost or 127.0.0.1 as Mikhail said, or you could map example.com domain to 127.0.0.1 in /etc/hosts (as I did) and it will solve the problem. If you choose the latter approach, make sure you access the web interface using http://example.com:8000/admin

This looks similar to this post
with your limited error description I can only suggest a few things that were mentioned in the above post:
Older Django versions use MIDDLEWARE_CLASSES = (...) in the settings.py rather than MIDDLEWARE = (...) try changing that variable.
If you are using virtualenv be sure to activate it before trying to runserver
If you created your app in a different version of Django and then installed it on another version it might give you errors.
I'm running nginx, gunicorn and wagtail on Ubuntu 16.04. I am not using virtualenv. Both nginx and gunicorn seem to work just fine but when I go to my domain in a browser (let's say myweb.com) I get a disallowed host error.
This seems like a simple problem but I have already added myweb.com as an allowed host in base.py like so: ALLOWED_HOSTS = ['myweb.com']. It even says in the request information that myweb.com is an allowed host in the settings file but it seems like wagtail is just ignoring that. I also tried turning debug off in the dev settings but it still showed me the debug screen.
Edit: The specific error message is (with myweb.com instead of the actual domain):

There was quite a bit more information on the page but I think this is everything that might be relevant to the problem
Gunicorn needed to be restarted. I don't know if it's supposed to work like this but on my setup it seems like Gunicorn always needs to be restarted to detect changes made to the project files.
I am trying to install "Django Registration Redux".
I followed every step in the official website to install.
When I am installing django.contrib.sites, the admin doesn't work, and when I comment this the admin starts working but registration does not work in either way.
It gives the error as:

It sounds like you haven't followed the instructions to enable the sites framework.
After adding django.contrib.sites to INSTALLED_APPS, you need to set SITE_ID = 1 in your settings, then run the migrate command.

I recently deleted a Django App "polls_ChoiceField" which was sitting inside another app "polls" as I was only using it to test a few things. However since i deleted it then the app it was sitting in no longer works.
I deleted the file through the pyDev package explorer. When I synced the Database it gave my the option of deleting the stale content, I selected yes.
Can anyone tell me what I have to do to get the original "polls" all running again?
Relevant Terminal output
localhost:src brendan$ python manage.py syncdb
Creating tables ...
The following content types are stale and need to be deleted:
polls | choice_choicefield
polls | poll_choicefield
Any objects related to these content types by a foreign key will also
be deleted. Are you sure you want to delete these content types?
If you're unsure, answer 'no'.
Type 'yes' to continue, or 'no' to cancel: yes

Installing indexes ...
Installed 0 object(s) from 0 fixture(s)
I then synced the DB
localhost:src brendan$ python manage.py syncdb
Creating tables ...
Installing custom SQL ...
Installing indexes ...
Installed 0 object(s) from 0 fixture(s)
And I am able to run the server
localhost:src brendan$ python manage.py runserver

When i try to revisit the app in my browser i get

Thanks
EDIT:
My urls.py with the bad line of code (the middle url)
urlpatterns = patterns('',
url(r'^polls/', include('polls.urls', namespace="polls")),
url(r'^polls_ChoiceField/', include('polls_ChoiceField.urls', namespace="polls_ChoiceField")),
url(r'^admin/', include(admin.site.urls)),
)
Thanks again.
Check your project-level urls.py, looks like it still tries to use urls from the deleted app.
My first post here. I have started learning Django over the past week. I have experience with other languages such but am also fairly new to python.
I have been going through this book: http://withdjango.com It has been great so far, however it was written when Django was at version 1.0 if I can tell correctly. However I am using Django 1.6.
I have managed to figure out a few of the small differences between the two here and there, however I am stuck on this one.
I have attempted to follow along with there 'pastebin' exercise (all of the source code is here http://withdjango.com.s3.amazonaws.com/src/pastebin.zip)
One thing I noticed was they used:
from django.views.generic.list_detail import object_list, object_detail
from django.views.generic.create_update import create_object
Where as in 1.6, if I am correct it should be
from django.views.generic.list import ListView
from django.views.generic.detail import DetailView
from django.views.generic.edit import CreateView
However when I launch this set of code which I have written. I get the following error:
> TypeError at /
> __init__() takes exactly 1 argument (4 given) Request Method: GET Request URL: http://[REMOVED FOR SECURITY] Django

Does anyone have any idea? I should also mention that I have tried using the exact source code the provide online, only changing those changes I mentioned.
Sorry if this is obvious, but I am brand new to all of this. Thank you for any help!
Django 1.0 and latest stable 1.6 have great differences. I advise learning through a more updated book. Particularly Django's own tutorial or Two Scoops of Django have great material (the latter book is going to be updated for 1.6 in near future).
