error:AttributeError: 'super' object has no attribute 'db_type' when run "python manage.py syncdb" in django

Question

I am working on a django project and I have two databases "mysql " and " neo4j" .I install neo4django package and change the setting.py like below:

setting.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'mylifetime',                     
        'USER': 'root',
        'PASSWORD': 'mypassword',
        'HOST': '',                      
        'PORT': '',
    }
}
NEO4J_DATABASES = {
    'default' : {
        'HOST':'localhost',
        'PORT':7474,
        'ENDPOINT':'/db/data'
    }
}

and my models currently have only neo4j models:

models.py:

from neo4django.db import models


class User(models.NodeModel):
    ...
    #my User models ...
    ....
class Post(models.NodeModel):
    ...
    #my Post models
    ...

when i run this command python manage.py syncdb I got error :

$ python ../manage.py syncdb
Creating tables ...
AttributeError: 'super' object has no attribute 'db_type'

When I use only MySql models I don't see the errors and tables will create successfully. where Am I wrong ? thanks

EDIT: when I write python manage.py syncdb --traceback I see below :

Creating tables ...
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/base.py", line 222, in run_from_argv

    output = self.handle(*args, **options)

    return self.handle_noargs(**options)

    col_type = f.db_type(connection=self.connection)

    return getattr(target, name)
AttributeError: 'super' object has no attribute 'db_type'

thanks.i don't insert DATABASE_ROUTERS = ['neo4django.utils.Neo4djangoIntegrationRouter'] following in the neo4j_docs in the settings.py.but really what is it ? — mojibuntu

Use the --traceback option to manage.py to see a full stack trace of the exception you get.

As noted in the docs, if you want to run against Neo4j and a relational DB, you need to add neo4django.utils.Neo4djangoIntegrationRouter to your DATABASE_ROUTERS in settings.py.
