mysql - Vanity 不适用于 MySql

Question

我尝试为我的 rails 2.3.5 应用程序安装 Vanity gem，我想使用 MySQL 作为 vanity。当我使用 redis 配置它时，一切都运行良好，但是当我将配置文件更改为使用 mysql 时:

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

我收到以下错误:

Showing

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

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

我在环境文件development.rb中添加了:

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

所以它必须对 vanity gem 中包含的适配器做一些事情，因为 redis 工作完美。有人知道解决方案吗？

Answer 1

我还没有找出原因，但我通过在 active_record_adapter.rb 文件中更明确地使用 has_many 关联的类名来让它工作:

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 vanity 时中断了迁移过程(我正在努力修复!)，但可能会帮助您找到解决方案。
