Customizing active_admin interface

Question

I've a simple question about active admin interface.

In my application, I've a resource added to the active_admin. When I access the resource from active_admin, I get all records for that resource. When I select/access (as a show action) one record it shows details of that instance and all belongs_to associations but I don't know how to get the has_many or has_one association details in the show view?

Any ideas? I appreciate any feedback.

Thanks,
Atarang.

You need to customize your show screen in app/admin/yourresource.rb. You shouldn't need to do anything special otherwise, other than making sure the has_many and belongs_to associations are correct. For example, if you have a category with many items, do this in category.rb:

show :category do
  panel "Category Info" do
    attributes_table_for category, :name, :created_at
  end
  panel "Items in This Category" do
    table_for(category.items) do
      column("Name", :sortable => :name) {|item| item.name }
      column("Created At") {|item| item.created_at }
    end
  end
end

There are more good examples here and elsewhere in the source for the demo project, which for some reason is hard to find from the main site.
