我正在开发一个django项目,我有两个数据库“mysql”和“neo4j”.我安装neo4django包并更改如下的setting.py：

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'
    }
}

我的模特目前只有neo4j型号：

models.py：

from neo4django.db import models


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

当我运行此命令python manage.py syncdb我收到错误：

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

当我只使用MySql模型时,我没有看到错误,表格将成功创建.
我哪里错了？
谢谢

编辑：
当我写python manage.py syncdb –traceback时,我看到如下：

Creating tables ...

解决方法:

使用–traceback选项manage.py查看您获得的异常的完整堆栈跟踪.
