Question

I have a model that needs editing that is associated with the current user called BillingProfile. How can I add a menu item that links to the edit page of the current user’s BillingProfile? I don’t want or need an index page for the BillingProfile as a user can only edit their own.

class User
  has_one :billing_profile
end

Answer 1

You can use Cancan to manage the ability to allow a User to edit his own Billing Profile.

ability.rb

...
cannot :edit_billing_profile, User do |u|
  u.user_id != user.id
end
...

admin/users.rb

ActiveAdmin.register User do
  action_item :only => :show do
    link_to "Edit BP", edit_bp_path(user.id) if can? :edit_billing_profile, user
  end
end

Or you can try something like this:

ActiveAdmin.register User do
  form do |f|
    f.inputs "User" do
      f.input :name
    end
    f.inputs "Billing Profile" do
      f.has_one :billing_profile do |bp|
        w.input :address if can? :edit_billing_profile, bp.user
      end
    end
    f.buttons
  end
end

I have not test it, but I did something similar on a project.
