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)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate

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

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!

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。
