I have belongs_to and has_many assotiations between two models. By default, activeadmin using select input for it. But in my case, it's imposible - because I have a thousands items. When I trying change filter to
filter :item, as: :string
it says that
undefined method `item_id_contains' for #<MetaSearch::Searches::DeliveryTime:0x007fdd57f12db8>
What is the best way to do it right?
