应用错误收集

我刚刚通过./manage.py schemamigration --auto生成了迁移脚本并运行了它。我收到以下错误。我很难过这可能意味着什么。我一直在使用SET_NULL一段时间。所以这是一种新的事先没有发生的事情。知道什么可能是错的吗？

Traceback (most recent call last): File "./manage.py", line 16, in execute_from_command_line(sys.argv) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/django/core/management/init.py", line 399, in execute_from_command_line utility.execute() File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/django/core/management/init.py", line 392, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/django/core/management/base.py", line 242, in run_from_argv self.execute(*args, **options.dict) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/django/core/management/base.py", line 285, in execute output = self.handle(*args, **options) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/management/commands/schemamigration.py", line 111, in handle old_orm = last_migration.orm(), File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/utils/init.py", line 62, in method value = function(self) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/migration/base.py", line 432, in orm return FakeORM(self.migration_class(), self.app_label()) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/orm.py", line 48, in FakeORM _orm_cache[args] = _FakeORM(*args) File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/orm.py", line 134, in init self.retry_failed_fields() File "/home/vivekv/.environments/fantain/local/lib/python2.7/site-packages/south/orm.py", line 377, in retry_failed_fields fname, modelname, e ValueError: Cannot successfully create field 'winner' for model 'match': 'module' object has no attribute 'SET_NULL'.
