Active_admin + Composite_primary_keys

Question

我使用复合主键gem和active_admin，索引页有问题。我可以以某种方式自定义index.html.arb文件吗？还是改变belongs_to协会？

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]**

app/admin/vehicles.rb

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

结束

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):

Answer 1

我认为active_admin不接受复合密钥。=/ (Rails )

无论如何，查看下面的链接，它可能会帮助您，并解释为什么active_admin查询索引页面中的所有belongs_to关联。
