django - Django 1.6.5 和 factory_boy 的异常

Question

我决定在我的简单 django 应用程序中使用 factory_boy 进行测试。
但我有一个简单的例子的问题。这是我的简单测试的代码。

from django.utils import unittest
from ..models import Server, ServerAddress, L2TPServer, serialize_open_vpn_server_json

from factory import django as django_factory


class SshOpenVpnServerFactory(django_factory.DjangoModelFactory):
    class Meta:
        model = L2TPServer
        django_get_or_create = ('name', 'address')

    name = 'Hello'
    address = 'Nono'


class ServersTestCase(unittest.TestCase):

    def test_serialize_server_info(self):
        print Server.objects.all()
        SshOpenVpnServerFactory.build()

当 test-runner 执行这个测试时，我收到一个错误:

Traceback (most recent call last):
  File "/Users/green/Development/Wasel/experimental/wasel_services/packages/waselcore/backend/tests/test_models.py", line 20, in test_serialize_server_info

    cls._setup_counter()

    first_seq = cls._setup_next_sequence()
  File "/Users/green/Development/Wasel/experimental/env/wasel_sevices/lib/python2.7/site-packages/factory/django.py", line 83, in _setup_next_sequence
    manager = cls._get_manager(model)
  File "/Users/green/Development/Wasel/experimental/env/wasel_sevices/lib/python2.7/site-packages/factory/django.py", line 76, in _get_manager
    return target_class.objects
AttributeError: 'NoneType' object has no attribute 'objects'

我哪里错了？ factory_boy 支持 django 1.6.5 吗？

建议的语法使用 Meta class 将仅作为(未发布的)Factory Boy 2.4 的一部分发布。使用 SshOpenVpnServerFactory.FACTORY_FOR反而。相关问题:https://github.com/rbarrois/factory_boy/issues/143
