The place to start is `reflect_on_all_associations`: http://api.rubyonrails.org/classes/ActiveRecord/Reflection/ClassMethods.html#method-i-reflect_on_all_associations This will give you all the associations defined for the model. You can then request the option you're interested in thus: ``` klass.reflect_on_all_associations do |reflection| if reflection.options[:dependent] # do something with it end end ``` --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
