我在基于测验的小应用程序中使用Active Admin gem。但是当我执行 rake db：migrate 时，它会给我错误。以下是命令的跟踪：

$ rake db:migrate RAILS_ENV=production --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)

An error has occurred, all later migrations canceled:

我搜索了上述问题并获得this，但这并没有帮助我。我到处都找到了这个解决方案。 有没有人之前遇到过这个问题，如果是的话你做了什么来解决它？任何有关这方面的帮助将不胜感激。感谢

当我尝试部署到新的登台服务器时，我也在我现有的应用上遇到了这个问题。

结果是Devise gem已经更新到2.1并且我没有修复迁移以使用新版本正常工作。

请务必阅读他们在wiki上迁移到2.1 doc的文档 - https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.1

另外，请务必仔细阅读文档，了解如何正确调整现有迁移 - https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.0-migration-schema-style

答案 1 :(得分：13)

我遇到过两次这样的问题，并且有一个非常简单的解决方案 - 而不是数据库迁移，请运行：

heroku run rake db:create 
# optionally with --app your_apps_name if you have multiple apps.

然后：

rake db:schema:load

答案 2 :(得分：8)

我刚认为是同样的问题，我更新了我的gem，并删除了我的数据库，后来我得到了一个非常相似的消息，然后我创建了一个新的rails应用程序只是为了进行比较，结果发现迁移文件已经已更改，现在它包括列而不是调用方法。

我希望它有所帮助。

干杯！

答案 3 :(得分：3)

我认为问题可能是Devise 2.0迁移架构风格的变化。在下面的链接中查看新的架构格式。相应地更新迁移，然后重试。这对我来说特别适用于#heroku

答案 4 :(得分：1)

您可以从我的代表处看到此站点的新功能。 John Kamuchau是正确的，您需要根据您的版本更改xxxx_devise_create_users.rb迁移。

例如我刚刚更新了一个rails 3.2到4.2更新设备，我不得不更改不推荐的 - 

t.database_authenticatable :null => false

for - 

## Database authenticatable
t.string :email,              null: false, default: ""
t.string :encrypted_password, null: false, default: ""

老问题，但希望如果有人来看，这会有所帮助。
