ruby-on-rails - 具有 HBTM 关联的 ActiveAdmin 自定义过滤器

Question

我希望能够过滤具有这种关联的对象

ActiveAdmin.register Vendor do
  filter :"market" , :as => :select, :collection => Market.all
end

Model Market
  has_and_belongs_to_many :vendors
Model Vendor
  has_and_belongs_to_many :associated_markets, :class_name => "Market"

但是我收到一个错误:

undefined method `market_eq' for #<MetaSearch::Searches::Vendor:0x007f9f5c02dd18>

Answer 1

  filter :associated_markets_id, collection: proc { Market.all }, as: :select
