Unable to find input class for json - handling JSON type in Active Admin

This works:

  permit_params :name, {:links => [:facebook, :twitter]}

  form do |f|
    f.inputs "Person Details" do
      f.input :name
    end
    f.inputs :name => "Links", :for => :links do |g|
      g.input :facebook, :input_html => { :value => "#{person.links['facebook']}" }
      g.input :twitter, :input_html => { :value => "#{person.links['twitter']}" }
    end
    f.actions
  end

It isn't the nicest solution, but unless someone has a better answer it will have to do.

There is a gem for that: https://github.com/udacity/activeadmin_json_editor

activeadmin_json_editor lets you edit JSONb fields with a structured field editor. The admins should understand the concept of a hash or array but apart from that, it works out of the box.
