Question

我已将旧的Django 1.5版本项目升级到新的Django 1.7版本

我的主要问题是迁移。

我按照upgrading from south to django migrations进行了新的迁移。

现在，当我运行测试用例./manage.py test时，在创建testDB时出现错误，并且在将迁移应用到新数据库./manage.py migrate

时会发生同样的错误

任何人都可以帮助我解决这个问题，这可能是迁移的错误

Answer 1

似乎：

... 0001_initial

导致您的错误。这可能是从南方监督的移民吗？我建议清空所有迁移包（但不是init文件！）并使用（windows）重新命令命令行中的迁移：

$ cd <your projects'-path>
$ python manage.py makemigrations
$ python manage.py migrate

django 1.7测试/应用迁移到新数据库时的迁移问题（将现有的django 1.5项目升级到django 1.7）
