mongoDB 和 Django TypeError: __init__() 正好需要 2 个参数（1 个给定）

Question

我已经安装了以下，来自link

django-nonrel 

djangotoolbox 

mongodb-engine 

我把我的installed_apps从

INSTALLED_APPS = (
   .. apps ..
)

到

INSTALLED_APPS = [
   .. apps ..
]

但我收到如下错误，

Validating models...

TypeError: __init__() takes exactly 2 arguments (1 given)

我正在使用 Django 1.5 和 python 2.7

提前致谢

django-nonrel是 Django 1.3 的一个分支，所以你不能在 Django 1.5 中使用它。尝试卸载 Django 1.5。
