I am installing byteflow-0.7 on python 2.6.5 with django 1.3 on windows7(64-bits). Database used is MySQL 5.0.51b on wamp 2.0 server. I installed all the prerequisites well and have run the syncdb command. That run well and the database was created successfully. When I run the server and hit the localhost:8000 on my browser, I see the following:

AttributeError: 'AdminSite' object has no attribute 'root'
What do I need to do?
It seems that AdminSite.root had been marked deprecated in Django 1.1 and apparently it is now removed in Django 1.3. So you either have to downgrade Django to 1.0 (as this is what ByteFlow website says in requirements) or use a newer Byteflow version that has this issue fixed.
PS. Found a fix in a forked repo.

I have been working through the Web with Python and Django with the CS50 course.
When i got to the stage of 'makemigrations' it didnt run and not i cant use the command 'runserver' either.

I was told that I could use the CS50 API to make things easier, but I am using VS Code on a Windows machine. I also know that the lecturer uses Mac. Does anyone know how to solve my problem? Thanks
-Max
EDIT:After going through the tutorial again from scratch i got the same problem. While looking through the syntax there was an error:
ModuleNotFoundError: No module named 'flights.url'
I went to the location that this was displayed and then realised i had forgotten a 's' in flights.urls. This was possibly not the problem i had in the past but now my code is allowing me to makemigrations.
I'm upgrading a Django project from 1.8 to 1.9,
I deleted the database file and all cache files, then I tried to run

Are there any edits or updates should I make in Settings.py?
This question isn't related to your upgrade. You have a query inside your urls.py, where you do 'extra_context' : get_latest_news(). That executes as soon as the URLs are imported; so the migrations can never have a chance to run.
Note that as well as blocking the migrations, this code would give you out-of-date results, for the same reason: it is executed on import, not when the request is run. Remove that query and move it into the view itself.
Nevertheless, you really shouldn't have deleted the database, or the migration files.
After python3 manage.py makemigrations or python manage.py makemigrations
I did python3 manage.py migrate --fake or python manage.py migrate --fake.
It somehow worked. I did this fake migration after that I had commented out a ForeignKey, the model to the ForeignKey and the model in admin.py. I then went and looked in the admin, and the ForeignKey model was gone. So I did add that ForeignKey, model and admin.site.register back and did a real migration, the error was gone.
When i run python manage.py runserver 8000
one file fuzzy.xml comes first and when I delete that file from that directory it sends error

What should I do?
Your read-only postgresql user for the datastore database is not setup correctly: the user has write privileges. The relevant part of the docs is: http://docs.ckan.org/en/latest/maintaining/datastore.html#set-permissions
I too faced the problem like this....I have deleted the user "datastore_default" from the postgres. For Deleting the Postgres User Please refer: Postgres Delete user
And create again the postgres user "datastore_default" as per the CKAN Documentation. Please ref: Create User datastore_default for CKAN
I have recently upgraded the version of Django from 1.5.5 to 1.6.2 and Mezzanine to 3.0.9.
When I run
python manage.py test
All the tests run without problem.
But When I run project specific tests using
python manage.py test <project-name>
Then I get ImportError. I get that its something to do with Circular Imports.
Here is the stack trace. Please help.
