在我的最新提交中，我向名为Submissions的表/模型添加了一个名为“accepted”的布尔列。它在我的测试和开发环境中迁移得很好，但是当我把它推到Heroku时，它似乎不起作用。推后我用过：
heroku run rake db:migrate
这是输出：
Running `rake db:migrate` attached to terminal... up, run.2430

在日志中我收到此错误：
ActionView::Template::Error (undefined method `accepted' for #<Submission:0x00000005e71080>):
当然，我没有在开发中遇到类似的错误。有什么建议吗？我的迁移失败了吗？
答案 0 :(得分：0)
迁移未添加到提交中。我修好了，现在似乎工作了。
