我有一个问题。
我使用的是项目，它使用rails 2.3和ruby 1.8.7。我的任务 - 更新到rails 4.0.1。
但我之前需要测试这个应用程序。此应用程序没有迁移，因此我使用rake db:schema:load但是当我启动此命令时，我看到此错误。
rake db:schema:load --trace
(in /home/alxgol/Projects/nucleus-core)

Mysql::Error: Table 'core_development.payments' doesn't exist: SHOW FIELDS FROM `payments`
我认为出现此问题是因为表payments中的信息在创建此表之前调用。但我没有找到，这个电话在哪里

解
如果仔细查看错误，您会看到它引用了/home/alxgol/Projects/nucleus-core/config/initializers/site_config.rb:15。在此文件中是来自付款表的电话。我注释掉了这个，然后在那个rake db：schema：load完成了工作。

如果仔细查看错误，您会看到它引用了/home/alxgol/Projects/nucleus-core/config/initializers/site_config.rb:15。在这个文件中是从payments表调用的。我评论了这一点，之后rake db:schema:load完美地运作了。
