I have django.contrib.auth in my installed apps and everything was was working about 10 minutes ago. I deleted the existed database because I had problems with south migrations. When I try to rebuild it I get an error.
Error: django.db.utils.DatabaseError: no such table: auth_user

**django.db.utils.DatabaseError: no such table: auth_user**
The problem is that you are running a query against the User model
File "/home/bruk/workspace/hungryDroid/src/hungryDroid/Ingredient/models.py", line 26, in Ingredient
FKowner = models.ForeignKey(User, default=User.objects.get(pk=1).id)
In the syncdb process (during field declaration actually, so any time your module is imported, like during this validation process).
This will make sure that the auth_user query is executed before the auth_user table is created.
A safer way to get the functionality with the default user is to do
def get_default_user():
return User.objects.get(pk=1)
And then in your field declaration, do
FKowner = models.ForeignKey(User, default=get_default_user)
As per the model field reference default can be a callable. Note that you would have the same problem if you used get_default_user() in there - then it executes immediately, not on-demand.

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

it works fine on django1.8 without any error!
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Note that as well as blocking the migrations, this code would give you out-of-date results, for the same reason: it is executed on import, not when the request is run.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.
I'm currently trying to upgrade an existing django-cms site from 3.0.16 to 3.1.4 with django 1.7.11
I followed the instructions given in http://docs.django-cms.org/en/latest/upgrade/3.1.html but when I get to python manage.py migrate
I get the following error:
django.db.utils.OperationalError: (1054, "Unknown column 'cms_page.path' in 'field list'")
Any hints on how I can debug this? Thanks!

I'm not sure why this worked, but the traceback indicated that there was some problem in my projects urls.py
I commented out all of the url rules in this file, migrated the cms app, then uncommented my url rules. That seems to solve the migration problem.
I have an actions.py file which defines custom actions for the admin page for one of my models. It uses an intermediary page (like the default delete action) and hence has a corresponding form which is also declared in the same file.
For some reason, I had drop by database (development) and now when I try to run syncdb, it gives me the following error:

iiitd is the name of one of my apps. The reason this is happening is because actions.py imports the iiitd_clientinfo model - but that doesn't exist yet, obviously. Currently, I make it work by excluding/commenting out my actions.py file. Surely, there has to be a work around?
I have tried the following:
south migration before syncdb - same error.
sorted out the INSTALLED_APPS order to ensure that they are in a topological order- same error

except ClientInfo.DoesNotExist:
raise Exception('Please add a client info object to the client')
It's mostly a wild guess until you post the source for your actions.py module, but from the traceback I assume line 16 is at the top level of your SelectUserForm class body. If so, this statement will be executed each time the module is imported, which is a BadThing for many reasons. You just discovered one of these reasons, congrats. Another one is that this will be executed once per process, and only once per process, which leads to to strange bugs as soon as you're in production (stale state, incoherent state from one process to another, etc).
The cure here is to move this statement within a method of your form.
I installed dajaxice into a django project. When i run the web using manage.py runserver, all went well. Now I try to deploy it with apache/wsgi. When I run manage.py collectstatic, error occur:
ImportError: cannot import name Bag
where Bag is one model within my app.
I tried
manage.py shell
then import Bag, i works well.
And I tried comment out DajaxiceFinder from settings.py, collectstatic finished normally.
Could any one help me out?
Thanks

from emini.repairment.models import Bag
ImportError: cannot import name Bag
Enviroment:
Django==1.5.4
django-dajaxice==0.5.5
I try to delete the import Bag from express/models.py, then collectstatic successed.
Structure of my apps:
emini
express
models.py
repairment
models.py
in emini.express.models:
from emini.repairment.models import Bag
class Package(models.Model):
foo = models.CharField(max_length=20)
class BagPackageLink(models.Model):
bag = models.ForeignKey(Bag)
package = models.ForeignKey(Package)
class Meta:
unique_together = (("bag", "package"),)
in emini.repairment.models
class Bag(models.Model):
foo = models.CharField(max_length=20)
Am i messing up with 'overlap import'?
But why the runserver and shell can import Bag model?
I have a new server just installed. Everything seems to be fine but when i run:
python manage.py syncdb
it generates follow error:

All the tables and fields, in fact, created automatically without observable problem. I just wanna get rid of this error becoz the same thing does not happen in my old server with exactly the same project running on it.
So I am answering it here so that other people can have answer of same problem:
As said by Bill Kary:
He have solved this himself. Change all the collation of ALL tables AND fields to utf (utf8_general_ci) stops the error beautifully.
