虚荣心不适用于MySql

Question

我试图安装虚荣宝石为我的轨道2.3.5应用程序，我想用虚荣的MySQL。一切是伟大的工作，当我和Redis的配置，但是当我更改配置文件来使用mysql：

development: 
    adapter: active_record 
    active_record_adapter: mysql 
    host: localhost 
    database: vanity 
    username: root 
    password: 

我得到以下错误：

Showing 
/Users/dries/.rvm/gems/ruby-1.8.7-p302/gems/vanity-1.5.3/lib/vanity/templates/_ab_test.erb where line #1 raised: 

Vanity::Adapters::ActiveRecordAdapter is not missing constant 
VanityConversion! Extracted source (around line #1): 

1: <% score = experiment.score %> 
2: <table> 
3: <caption> 
4:  <%= experiment.conclusion(score).join(" ") %></caption>

/Users/dries/.rvm/gems/ruby-1.8.7-p302/gems/vanity-1.5.3/lib/vanity/templates/_report.erb 

我在环境文件development.rb补充说：

Vanity.playground.establish_connection :development 
Vanity.playground.collecting = true 

所以它必须做一些与虚荣宝石中包含的适配器，因为redis工作正常。有人知道解决方案？

Answer 1

我还没有想出这个原因，但我得到了它通过与在active_record_adapter.rb文件中的has_many关联的类名称更明确的工作：

has_many :vanity_metric_values, :class_name => "Vanity::Adapters::ActiveRecordAdapter::VanityMetricValue" 
has_many :vanity_conversions, :dependent => :destroy, :class_name => "Vanity::Adapters::ActiveRecordAdapter::VanityConversion" 

编辑：这似乎在第一次启动虚荣时破坏了迁移过程（我正在努力解决这个问题！），但可能会帮助您找到解决方案。
