'NoneType' object has no attribute 'converter'

Description of problem:
MySQL connector for Django provided by mysql-connector-python is not compatible with django-1.6.2, which will be soon available in Fedora 20.


Version-Release number of selected component (if applicable):
mysql-connector-python-1.1.5-1.fc20.noarch
python-django-1.6.2-2.fc20.noarch
mariadb-server-5.5.36-1.fc20.x86_64


Steps to Reproduce:
1. create default project:
$ django-admin startproject test1; cd test1

2. create database:
$ echo create database test1 | mysql

3. setup django to use mysql.connector.django as database backend:
$ grep -A 4 -B 2 mysql.connector.django test1/settings.py
DATABASES = {
    'default': {
        'ENGINE': 'mysql.connector.django',
        'NAME': 'test1',
        'USER': 'root',
    }
}

4. sync db:
$ python manage.py syncdb

5. run server:
$ python manage.py runserver

6. visit admin site at: http://127.0.0.1:8000/admin/

Actual results:
Exception Type: AttributeError at /admin/
Exception Value: 'NoneType' object has no attribute 'converter'
(attached traceback)

Expected results:

Comment 1 Remi Collet 2014-04-16 15:30:45 UTC 
So obvioulsy, if this upgrade of django breaks such thing, it should not be push to stable release F20.
Comment 2 Remi Collet 2014-04-16 16:09:28 UTC 
I just push mysql-connector-python-1.1.6-1.fc20.noarch to testing.

Please test it 

According to changelog it fixes a bug with Django backend (but according to previous entries in changelog, it should work with 1.6).
Comment 3 Jakub Dorňák 2014-04-16 20:07:35 UTC 
It works fine with these versions:
mysql-connector-python-1.1.6-1.fc20.noarch
python-django-1.6.2-2.fc20.noarch
mariadb-server-5.5.36-1.fc20.x86_64
Comment 4 Jakub Dorňák 2014-04-16 20:20:24 UTC 
I am changing the severity, because I realized, that most of the applications probably use Django's default mysql backend, which uses MySQL-python. Therefore this should not affect them. I use django backend from mysql-connector-python, because MySQL-python is not available for python3.

This reminds me to note that it also works with python3 variants:
mysql-connector-python3-1.1.6-1.fc20.noarch
python3-django-1.6.2-2.fc20.noarch

Thank You for very fast update.
