django - 南0.8.3升级导致DeserializationError

Question

我有一个使用 South 0.8.2 的 Django 1.5.5 项目。一切都很好——包括使用 South 进行迁移。当我尝试将此项目升级到 South 0.8.3 时，运行 python manage.py migrate 时出现以下错误:

(VBEZ)vagrant@vagrant-ubuntu-precise-64:/vagrant$ python manage.py migrate
Running migrations for django_mailbox:
- Nothing to migrate.
 - Loading initial data for django_mailbox.
Installed 3 object(s) from 1 fixture(s)
Running migrations for djcelery:
- Nothing to migrate.
 - Loading initial data for djcelery.
DeserializationError: Problem installing fixture 'initial_data.json': Invalid model identifier: 'sites.site'

发生了什么事？

这是我的 initial_data.json文件:

[
  {
    "pk": 1, 
    "model": "sites.site", 
    "fields": {
      "domain": "0.0.0.0:5000", 
      "name": "Project (Development)"
    }
  }, 
  {
    "pk": 2, 
    "model": "sites.site", 
    "fields": {
      "domain": "project-staging.example.com", 
      "name": "Project (Staging)"
    }
  }, 
  {
    "pk": 3, 
    "model": "sites.site", 
    "fields": {
      "domain": "project.example.com", 
      "name": "Project"
    }
  }
]

以下是使用 South 0.8.2 成功迁移的样子:

Running migrations for django_mailbox:
- Nothing to migrate.
 - Loading initial data for django_mailbox.
Installed 3 object(s) from 1 fixture(s)
Running migrations for djcelery:
- Nothing to migrate.
 - Loading initial data for djcelery.
Installed 3 object(s) from 1 fixture(s)
Running migrations for taggit:
- Nothing to migrate.
 - Loading initial data for taggit.
Installed 3 object(s) from 1 fixture(s)
Running migrations for eee_core:
- Nothing to migrate.
 - Loading initial data for eee_core.
Installed 3 object(s) from 1 fixture(s)
Running migrations for core:
- Nothing to migrate.
 - Loading initial data for core.
Installed 3 object(s) from 1 fixture(s)

我看过/尝试过的事情:

django-contrib-sites在我的“INSTALLED_APPS”中

如果 initial_data.json，迁移工作正常文件被删除。

如果我单独运行迁移，它们运行良好。示例 python manage.py migrate myapp .

我已提交工单:http://south.aeracode.org/ticket/1324

谢谢。

看起来这是 South 0.8.3 中的一个已知错误:http://south.aeracode.org/ticket/1320 .修复预计在一周左右。

更新 :South 0.8.4 修复了这个错误。
