Question

我正在尝试使用aws ec2实例中的django和mongodb创建博客

在models.py文件中，我正在进行以下更改

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])

并且，我收到此错误

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

并且，在settings.py文件中，我正在进行以下更改

那么，我该如何解决导入错误？

Answer 1

Django支持已从0.10.0中的MongoEngine中删除。您可能可以使早期版本工作，但它可能不支持最新版本的Django。

使用mongoengine 0.10我们可以看到

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

不会有django包。使用

安装mongoengine 0.9

sudo pip install mongoengine == 0.9

和django包（支持或扩展）将可用。

连接django与mongodb时出错：ImportError：没有名为django.auth的模块
