Ruby on rails Rails迁移——RakeDB:status说迁移已经停止，但数据库已经迁移了？

我有一个本地的PSQL数据库设置，在获取rake db:migrate以正常运行时遇到问题。例如，我的数据库已将其high_school列名更改为high_school_名称，但rake db:migrate失败，状态显示：

up     20130307043554  Adding seo tables
up     20130307185401  Create admin notes

up     20130410164209  ********** NO FILE **********
up     20130416142844  Add column coach id to users

为什么在迁移顺序中间的迁移失败/被读为“向下”？以下是错误：

显然，存在模式问题或其他问题。不过，架构是通过远程分支跟踪的，所以我不知道问题出在哪里。

我怀疑down无法正确处理列重命名更改，除非只是添加或删除列

<>你可能想考虑的是用SQL更改名称。例如，如果将

high\u school

更改为

high\u school\u name

的迁移失败，并且数据库本身当前具有

high\u school\u name

，请将其重命名为

high\u school

，然后尝试运行迁移。这可能是您的一个选项。

在要重命名列的行末尾添加resque nil to
