我正在将旧应用程序从 rails 2.3.2 移动到 2.3.18，将 ruby​​ 1.8.7-p72 移动到 1.8.7-p374。（然后在 ruby​​ 1.9.3 和 rails 3 之后）

我尝试的第一个应该很简单的查询给我带来了问题。在控制台中：

?> User.find(:all, :joins => { :sms_users => :join_smsuser_campaigns }, 
                   :conditions => { :sms_users => {
                                        :join_smsuser_campaigns => {
                                            :campaign_id => 18 } } })

看起来很简单？

它给了我：

只是为了确认我实际上可以创建一个用户类型：

?> User.find(1)
=> #<User id: 1, date_created: "2008-01-06 17:22:12", email: "email@example.com", name: "First Last", phone_number: "1234567890", last_communication: "2012-11-09 22:34:43">

所以，看起来我可以创建用户对象。

知道为什么这个简单的查询会失败吗？我已经阅读了 2.3.18 activerecord 文档，看起来我的例子就像他们展示的一些例子一样......也许我有一个导致问题的宝石？从堆栈跟踪中并不明显。

更改查询语法对我有用：

users = User.find(:all, :joins => { :sms_users => :join_smsuser_campaigns },
    :conditions => { 'join_smsuser_campaigns.campaign_id' => session[:campaign_id].to_i},
    :order => 'join_smsuser_campaigns.conversation_status DESC, join_smsuser_campaigns.last_communication DESC, sms_users.id ASC')
