Active_admin + Composite_primary_keys

我正在使用复合主键gem和active_admin,我遇到了索引页面的问题。 我可以以某种方式自定义index.html.arb文件吗?或者更改belongs_to关联?

我的模特:

 class Vehicle < ActiveRecord::Base
 self.table_name = "vehicle"
 self.primary_key = "vehicle_id"
 belongs_to :operator, :foreign_key => :operator_id
 **belongs_to :orgunit, :foreign_key => [:operator_id, :run_code]**

应用程序/管理/ vehicles.rb

ActiveAdmin.register Vehicle do
  index do
  id_column
  column  :version
  column  :description
  default_actions


索引页错误:

NoMethodError in Admin/vehicles#index
Showing /home/dev/.rvm/gems/ruby-1.9.3-p125@global/gems/activeadmin-
0.5.0/app/views/active_admin/resource/index.html.arb where line #1 raised:

undefined method `to_sym' for [:operator_id, :run_code]:Array
Extracted source (around line #1):

我认为active_admin不接受复合键。 = /(Rails)

无论如何,请查看下面的链接,它可能对您有所帮助,并解释为什么active_admin在索引页面中查询所有belongs_to关联。
