Do you have any suggestion?
You can try to see this :
Django 1.7.1 added support for the preserve_default param in AlterField. Therefore an upgrade of Django from version 1.7 will resolve the issue.
pip install django --upgrade
python manage.py migrate
From : Django 1.7 Migrations

I'm developing a project with Django CMS 3.5. I used SQLite for development and have data in there. Now I'm trying to migrate to PostgreSQL. My steps so far:
python manage.py dumpdata --natural-primary --natural-foreign > dump.json
Switching to production settings
python manage.py migrate
TRUNCATE django_content_type CASCADE;
python manage.py loaddata dump.json
But I encounter the next error:

I'm new to South and I'm trying to perform a migration. It worked fine in local, but when I pushed the code to Heroku and tried to migrate I got this error:

In local I did:
python manage.py schemamigration spicemodels --auto
python manage.py migrate spicemodels
Then I pushed the migration files to Heroku and accessed the app using:
heroku run bash --app <app-name>
I then went into the correct directory and ran:
python manage.py migrate spicemodels
That is when I got the error above.
I am trying to apply tutorial http://docs.django-cms.org/en/2.1.3/getting_started/tutorial.html.
But I didn't succeed to perform the initial database setup
Why do I get this error when I run "python manage.py syncdb --all" ?

The verify_exists parameter for UrlField was deprecated in the 1.3.1 security release and removed in the current Git master (1.5dev). https://docs.djangoproject.com/en/1.4/internals/deprecation/. This makes this version of django-cms incompatible with the current master. I would recommend using a stable Django release such as the latest 1.4 rather than master.
my django app run with mysql, but when i try with mongodb then show thie error

** I have installed all necessary module installed, but when i want to runserver then show this message
I managed to fix the same error by using these packages on github:
https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox
instead of the ones recommended on Django-Mongodb's setup page. Also, make sure to use the master branch of each, so as to not run into compatibility problems. If you're using pip, you can either pip install each of the following lines separately, or put them into your version of a requirements.txt file for your project:
git+https://github.com/django-nonrel/django-nonrel#master
git+https://github.com/django-nonrel/djangotoolbox#master
git+https://github.com/django-nonrel/mongodb-engine#master
And then run
pip install -r requirements.txt

yes, that was errors..
But I'm a bit confuse, sudo or not sudo...python manage.py sync_cassandra or sudo python manage.py sync_cassandra
Solved. without sudo is the right. It will use python version from virtual environment
