How can I specify available ActiveScaffold actions on a per-record basis?

I have a very simple admin controller in my Rails 2 app that displays all the records for a model read-only:

class Admin::InspectionsController < ApplicationController

  active_scaffold :inspections do |config|
    [:create, :update, :delete].each {|a| config.actions.exclude a}
    config.actions.exclude :nested
  end
end

I wish to make these model objects editable, but only if they are in a certain state (ie, before they've been approved). I can do this for all Inspections by removing :update from the exclusions list, but I don't want to enable editing wholesale.

Is there a way to specify conditional actions to ActiveScaffold?

Solution

I think you are looking for this: https://github.com/activescaffold/active_scaffold/wiki/Security. Head down to 'Model Methods: Restricting Anything Else'

Long story short, you enable all actions, and then add methods to your model definition to toggle said actions for each record, as described in the link.
