Question

I’m working on an application with an ActiveAdmin backend and having a hell of a time getting it to render a fairly simple custom index view.

I have a number of ‘request’ records, which contain an email address and a book_id, by which they need to be grouped. I got as far as:

ActiveAdmin.register Request do
  controller do
    def index
      @requests = Requests.group(:book_id).page
    end
  end
end

but this resulted in an error: ActiveSupport::OrderedHash can’t be coerced into Fixnum

I can create my own custom view in app/admin/requests/index.html.erb but then I lose the standard AA layout with the admin menu et all and can’t find a good way to include it.

Answer 1

I ended up doing this using a technique described on their Google Group, in which you just shove the user over to a custom action:

Hacky, yes. I think this is a much needed feature, so hopefully someone can fork and add in support for the index view to take a block with custom content.
