Django South迁移正在抛出错误'module'对象没有属性'SET_NULL' [英] Django South migration is throwing an error 'module' object has no attribute 'SET_NULL'
问题描述
我刚刚通过 ./ manage.py schemamigration --auto 生成迁移脚本并运行它。我收到以下错误。我对这可能意味着什么？我一直在使用SET_NULL一段时间。所以这是早期没有发生的新事物。任何想法可能是错的？
I just generated the migration scripts through ./manage.py schemamigration --auto and ran it. I get the following error. I am stumped as to what it could mean. I have been using SET_NULL for a while now. So this is something new that didn't occur earlier. Any idea what could be wrong?

推荐答案
确定这不是一个有效的问题。我很尴尬承认我对导致问题的迁移脚本做了一个小小的调整。请忽略这个问题 - 似乎我没有办法删除我问过的问题！
OK This is not a valid question. I am embarrassed to admit I made a small tweak on the migration script that caused the problem. Please ignore this question - seems like I dont have a way to delete a question I had asked!
