Djangonrol syncdb和mongodb：pymongo.errors.OperationFailu

Question

我在mongodb引擎中使用django-nonrl，在运行python时遇到以下错误管理.py同步数据库：

我不知道怎么了。我一直试图让mongodb与django合作，但我遇到了很多问题。我的设置.py公司名称：

^{pr2}$

我希望我已经发布了足够的背景信息。我真的很感激你的帮助。在

Answer 1

我的解决方案是修改 从这里：

ensure_index(column, unique=field.unique,
                     sparse=field.name in sparse_indexes)

为此：

^{pr2}$

它似乎可以清除错误，但我确信它会使某个地方发生灾难性的失败，因为我不知道我在做什么。在

我也会等待更好的答案。在

Answer 2

1.在MongoDB 3.2 3.4版本中测试syncdb，仍然会出现错误。在

2.在MongoDB 2.6中，syncdb运行良好，但有一个不相关的小问题。我在版本2.6中仍然遇到了一个错误，并用这个（https://gist.github.com/ielshareef/2986459）进行了修复。在

3.django_mongodb_引擎是从django1.3派生出来的。此外，本回购协议已过时，上次承诺日期为2015年7月13日。我不推荐这个套餐。在

4.我推荐https://github.com/MongoEngine/django-mongoengine

Answer 3

尝试使用3.2版的Mongo数据库，mongoengine和Mongo Server 3.4有问题
