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
python manage.py migrate
or
python manage.py migrate --run-syncdb
but always raise this error django.db.utils.OperationalError: no such table:
here is the full traceback

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Note that as well as blocking the migrations, this code would give you out-of-date results, for the same reason: it is executed on import, not when the request is run.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.

django.db.utils.ProgrammingError: relation "swsite_hitcounter" does not exist
LINE 1: INSERT INTO "swsite_hitcounter" ("date", "template_location"...
This is confusing to me as it is specifically trying to build the swsite_hitcounter table as in the following migration I am trying to fun:
# -*- coding: utf-8 -*-
# Generated by Django 1.9.5 on 2017-07-05 15:56
from __future__ import unicode_literals
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [
('swsite', '0022_auto_20170307_1343'),
]
operations = [
migrations.CreateModel(
name='HitCounter',
fields=[
('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
('date', models.DateTimeField(auto_now=True)),
('template_location', models.TextField()),
],
),
]
Is something maybe out of sink? This is me trying to run this migration on my production box, it ran fine (of course) on my development box. Might of been cause I ran a specific migration? :
python manage.py migrate swsite 0023_hitcounter.py
Though running:
python manage.py showmigrations
Gives me same error? I am guessing my migrations are out of sync but not being able to show migrations, I don't know how to show the ones that didn't get into this update (on production from gilab)
The traceback is showing you that the error is occuring in IndexView. You are trying to create objects in the database when the view loads.
class IndexView(TemplateView):
newhit = HitCounter.objects.create() # remove this line
...
Accessing the database when the views load like this is a bad idea, so you should probably remove the line. In production, it gives you the error because it is trying to create the object in the database before you have applied the migration that creates the table.
When I start tests I get error

django.db.utils.ProgrammingError
When I run my application on the localhost - all ok, it happens only with the test. This is my settings
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'some_project',
'USER': 'web',
'PASSWORD': '',
'HOST': ''
}
}
I use Django==1.8.4 and psql (PostgreSQL) 9.4.1.
I turned on database logs and nothing has been printed out on the console, but it works good when application normally running.
Also, I granted super user rights to the web user.
What is going wrong? How can I get more logs without debugging by hands?
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!

django.db.utils.OperationalError: (1054, "Unknown column 'cms_page.path' in 'field list'")
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 use django_celery with connecting to Amazon Redshift. To migrate database, after "makemigrations" I used command "python manage.py migrate" and error message show up as shown below.
The reason is Redshift does not support data type 'serial' but the 'django_migrations' table that contain 'serial' type is automatically created.
How to stop Django Migrations create this table or avoid using serial on 'django_migrations' table.
D:\code\test_celery_django>python manage.py migrate

Are you trying to use Redshift as the backend database for your web application? That's a bad idea, Redshift is a data warehouse and as such individual query performance and latency are far from great, not to mention that Redshift doesn't enforce primary keys, which almost surely Django expects.
My recommendation, use PostgreSQL.
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.
