Custom ActiveAdmin filter with HBTM associations

I would like to be able to filter an object using these associations

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

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


But I am getting the error:

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