How to create a nested custom page in ActiveAdmin?

Question

I need to create a nested custom page inside a resource.

The route should be like this:
/admin/quizzes/:id/my_custom_page

The problem is that we can't use belongs_to in ActiveAdmin::Page.

I could create the route manually of course, but would be great if the AA could handle this for us.

The documentation says nothing and the code is not so simple. :(

Any suggestion?

You can use member_action:

ActiveAdmin.register Quiz do

  member_action :my_custom_page, method: :get do
  end

end

And this will generate a route at /admin/quizzes/:id/my_custom_page

So obsviously... :P But do you know how to attach a Page instance to this member_action? Thanks!

This action will render the view under the path app/views/admin/quizzes/my_custom_page.html.erb

Yep! But could we have a Page instance instead? Thus we could take benefit of AA's dsl.

member_action does exactly what Page does, but related to a model. That is what you need, don't?

There are some features that couldn't be used when working with .erb (unless you include some modules).
