Question

我成功安装了django，目前尝试将它与Mongoengine结合使用。在设置应用程序后使用“python manage.py makemigrate”时，我收到以下错误：

    $PATH$\env\lib\site-packages\mongoengine\django\mongo_auth\models.py:14: RemovedInDjango18Warning: `MongoUserManager.get_query_set` method should be renamed `get_queryset`.
      class MongoUserManager(UserManager):

    Traceback (most recent call last):
      File "manage.py", line 10, in <module>

        pub_date = models.DataTimeField('date published')
    AttributeError: 'module' object has no attribute 'DataTimeField'

$ PATH $是我项目的路径。

该应用包含以下models.py:

    from django.db import models
    #from mongoengine import *

    class Question(models.Model):
        question_text = models.CharField(max_length=200)
        pub_date = models.DataTimeField('date published')

    class Choice(models.Model):
        question = models.ForeignKey(Question)
        choice_text = models.CharField(max_length=200)
        votes = models.IntegerField(default=0)

我正在使用django v1.7.1和mongoengine v0.8.0。该错误也可能源自我的项目中的settings.py文件，我编辑该文件以包含mongo db。

此外，我正在使用virtualenv为我的项目创建一个虚拟环境。不确定这是否也会影响该计划。

你有一个拼写错误：DataTimeField而不是DateTimeField。
