【问题描述】：
有人可以帮我解决这个问题吗：
我最近安装了 south 以使用它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 south 0.7.3）。
将我的名为签名的应用程序成功转换为南后，命令manage migrate signature 打印以下输出：
C:\python projects\suivireal>manage.py migrate signature
Running migrations for signature:
- Migrating forwards to 0002_auto__del_field_agent_titre_en__add_field_agent_ni
veau__add_field_agen.
> signature:0002_auto__del_field_agent_titre_en__add_field_agent_niveau__add_fi
eld_agen

我用谷歌搜索了这个问题是否与mysql有关，但我找不到出路。
【问题讨论】：
-
请解释一下在输入“迁移签名”之前您做了什么。
-
从“convert_to_south”开始，然后我在模型中做了一些更改，我添加了一个字段并更改了一个字段名称。之后，当我执行 schemamigrate 选项时，它要求我填写这些字段的默认值字段，我做到了，它工作正常。之后，我根据它的建议执行迁移，它对上面解释的错误进行排序。
