Question

我正在使用Django和MySQL。我安装了South，我正在尝试将我的应用程序从一个模式迁移到另一个模式。但是当我运行$ python manage.py migrate catalog时，我收到以下错误：

 - Migrating forwards to 0003_initial.
 > catalog:0003_initial
 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running
 ! schema-altering statements in transactions, we have had 
 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   = DROP TABLE `categories` CASCADE; []
   = DROP TABLE `product_shapes` CASCADE; []
   = DROP TABLE `materials` CASCADE; []
   = DROP TABLE `style` CASCADE; []
   = DROP TABLE `products` CASCADE; []
   = DROP TABLE `products_shape` CASCADE; []
   = DROP TABLE `products_materials` CASCADE; []
   = DROP TABLE `products_style` CASCADE; []
   = DROP TABLE `products_categories` CASCADE; []

 ! The South developers regret this has happened, and would
 ! like to gently persuade you to consider a slightly
 ! easier-to-deal-with DBMS.

有没有办法可以在不删除这些表的情况下进行迁移。我有一种感觉，如果我放弃表格，我将最终丢失我想要保存的数据。

编辑：

我认为这是主要错误：

_mysql_exceptions.OperationalError: (1050, "Table 'categories' already exists")

Answer 1

如果这些表中包含您要保存的数据，请不要删除它们。

如果没有看到实际错误，很难提供任何更具体的帮助，而错误应该遵循您引用的消息。

使用Django South进行模式迁移失败：我该怎么办？
