    # Here is an example of a simple dashboard with columns and panels.

I'm a little confused on how to access the association of a model. I understand the code is producing a list of all towns for each state here, but how do I get just the towns of each state to be listed?

My State model has_many :towns, and the Town model belongs_to :state

I've never really used Active Admin, but I think it should look something like

      column do
        panel "Towns" do
          ul do
            State.all.each do |state|
              li link_to(state.name, admin_state_path(state))
              ul do
                state.towns.each do |town|
                  li town.name
                end
              end
            end
          end
        end
      end
    end

If you have the relations set up properly, this should work. I'd jump into the rails console and do

state = State.first #pulls first state in your db
towns = state.towns #should return a list of town objects that belong to that state
