如果在我的模特中我有这样的关系: 模特学位:
class Degree < ActiveRecord::Base
has_and_belongs_to_many :states
accepts_nested_attributes_for :states, :allow_destroy => true
end
模型状态:
class State < ActiveRecord::Base
has_and_belongs_to_many :degrees
accepts_nested_attributes_for :degrees, :allow_destroy => true
end
如果我有如上所述的关系,如何覆盖索引度活动管理员状态的过滤器?
答案 0 :(得分:0)
你是否在degrees.rb中尝试过类似的东西:
ActiveAdmin.register Degree do
...
filter :states_id, :as => :check_boxes, :collection => proc {State.all}
...
end
