How to migrate back from initial migration in Django 1.7?
提问by Seppo Ervi?l?
I created a new app with some models and now I noticed that some of the models are poorly thought out. As I haven't committed the code the sensible thing would be to migrate the database to last good state and redo the migration with better models. In this case the last good state is database where the new app doesn't exist.
我用一些模型创建了一个新应用程序，现在我注意到有些模型没有经过深思熟虑。由于我还没有提交代码，明智的做法是将数据库迁移到最后的良好状态并使用更好的模型重做迁移。在这种情况下，最后一个好的状态是新应用程序不存在的数据库。
