錯誤與MongoDB的連接Django的：導入錯誤：沒有模塊名爲django.auth

Question

我試圖創建使用AWS EC2實例

，並在文件models.py Django和MongoDB的博客，我提出以下修改

from datetime import datetime 
from mongoengine import * 
from mongoengine.django.auth import User 
from django.core.urlresolvers import reverse 

class Post(Document): 
    user = ReferenceField(User, reverse_delete_rule=CASCADE) 
    title = StringField(max_length=200, required=True) 
    text = StringField(required=True) 
    text_length = IntField() 
    date_modified = DateTimeField(default=datetime.now) 
    is_published = BooleanField() 

from django.core.urlresolvers import reverse 

class Post(Document): 
    user = ReferenceField(User, reverse_delete_rule=CASCADE) 
    title = StringField(max_length=200, required=True) 
    text = StringField(required=True) 
    text_length = IntField() 
    date_modified = DateTimeField(default=datetime.now) 
    is_published = BooleanField() 

    def __unicode__(self): 
     return self.title 

    def save(self, *args, **kwargs): 
     self.text_length = len(self.text) 
     return super(Post, self).save(*args, **kwargs) 

    def get_absolute_url(self): 
     return reverse('detail', args=[self.id]) 

    def get_edit_url(self): 
     return reverse('update', args=[self.id]) 

    def get_delete_url(self): 
     return reverse('delete', args=[self.id]) 

而且，我得到這個錯誤

Traceback (most recent call last): 
     File "models.py", line 7, in <module> 
     from mongoengine.django.auth import User 
ImportError: No module named django.auth 

而且，在settings.py文件，我想提出以下更改

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))

那麼，我該如何解決導入錯誤？

在0.10.0中，從MongoEngine中刪除了Django支持。您可能能夠獲得早期版本，但它可能不支持最新版本的Django。

隨着mongoengine 0.10我們可以看到，

/usr/lib/python2.7/site-packages/mongoengine/

不會有Django的包在裏面。 安裝mongoengine 0.9使用

sudo pip install mongoengine==0.9

和django的包（支持或擴展）將可用。
