Rails association finder_sql proc{}不会返回所有表列

我的页面模型中有此关联

它通过NetworkPages模型中的页面ID检索网络。其表格如下：

1.9.3p392 :010 > Network
 => Network(id: integer, name: string, created_at: datetime, updated_at: datetime, column1: string, column2: string, inversion: boolean) 
1.9.3p392 :011 > NetworkPage
 => NetworkPage(id: integer, network_id: integer, page1_id: integer, page2_id: integer, created_at: datetime, updated_at: datetime) 

但是，当调用上面的关联时，我只得到记录的id和timestamp列作为返回：

1.9.3p392 :014 > page.networks
 => [#<Network id: 1, created_at: "2013-04-07 09:07:05", updated_at: "2013-04-07 09:07:05">]

我不太明白为什么会发生这种情况，如何检索所有网络模型属性？

您的finder\u sql从错误的表中选择了网络页面而不是网络

啊，是的，我想知道为什么它返回了网络类。rails是否正在尝试将返回的列与模型匹配？has_many:networks，：finder_sql=>proc{SELECT networks.*从网络内部连接网络上的网络页面。id=network\u pages.network\u id其中page1_id={id}或page2_id={id}它返回了一个网络，因为您说有很多网络。它不会尝试分析finder_sql的内容以查看正在使用哪些表

1.9.3p392 :014 > page.networks
 => [#<Network id: 1, created_at: "2013-04-07 09:07:05", updated_at: "2013-04-07 09:07:05">] 

1.9.3p392 :015 > page.networks.first.class
 => Network(id: integer, name: string, created_at: datetime, updated_at: datetime, column1: string, column2: string, inversion: boolean) 
1.9.3p392 :016 > page.networks.first.name
