我正在将我的更改从开发人员交付到生产人员的过程中。
一切都在开发中运行良好。
我正在使用 Django 1.4
我面临的问题是 South 没有接受并且没有为我正在使用的 manytomanyfield 创建一个表。
在 dev 上，我看到有 21 个 MySql 表，而 prod 上缺少 1 个表。
我真的不知道如何解决这个问题。
这是 South 第一次被添加到我的开发和产品中。
任何想法如何创建丢失的表？
这就是我所做的以及我收到的错误：
./manage.py schemamigration companies --auto --update
+ Added M2M table for companyjobs on companies.Company
Migration to be updated, 0003_auto, is already applied, rolling it back now...
previous_migration: 0002_auto (applied: 2013-05-04 06:19:38+00:00)
Running migrations for companies:
- Migrating backwards to just after 0002_auto.
< companies:0003_auto
FATAL ERROR - The following SQL query failed: DROP TABLE `companies_company_companyjobs` CASCADE;
The error was: (1051, "Unknown table 'companies_company_companyjobs'")
! 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.
! The South developers regret this has happened, and would
! like to gently persuade you to consider a slightly
! easier-to-deal-with DBMS (one that supports DDL transactions)
! NOTE: The error which caused the migration to fail is further up.
Error in migration: companies:0003_auto
