有人可以帮我解决这个问题： 我最近安装了南来使用它来更新生产服务器上基于django的项目中的更改（Appache 2.0，MySql 5.0，python 2.5，Mysqldb for python， Django 1.3和南0.7.3）。 将我的签名命名到南的应用程序，这是成功完成，命令manage migrate signature它输出以下后：south＆mysql问题

我用Google搜索，看它是否与MySQL有关的问题，但我不能找到一个出去的路。
请解释你在输入“迁移签名”之前做了什么。 – nicolas
以“convert_to_south”开头，然后我在模型中进行了一些更改，添加了一个字段并更改了字段名称。之后，当我执行schemamigrate选项时，它让我填写这些字段的默认值字段，我做了，它工作正常。在那之后，我根据它的重新命令执行迁移，它对上面解释的错误进行排序。 – Hakim
