如果我有關系，如何在active_admin中更改過濾器

Question

如果在我的模型中我有這樣的關系：模型度：

class Degree < ActiveRecord::Base
  has_and_belongs_to_many :states
  accepts_nested_attributes_for :states, :allow_destroy => true
end

模型狀態：

class State < ActiveRecord::Base
  has_and_belongs_to_many :degrees  
  accepts_nested_attributes_for :degrees, :allow_destroy => true
end

如果我有上述關系，如何在索引度活動管理員中覆蓋狀態過濾器？

Answer 1

您是否在degree.rb中嘗試過類似的方法：

ActiveAdmin.register Degree do
  ...
  filter :states_id, :as => :check_boxes, :collection => proc {State.all}
  ...
end
