How do I 'validate' on destroy in rails

Question

On destruction of a restful resource, I want to guarantee a few things before I allow a destroy operation to continue? Basically, I want the ability to stop the destroy oper

Answer 1

I have these classes or models

class Enterprise < AR::Base
   has_many :products
   before_destroy :enterprise_with_products?

   private

   def empresas_with_portafolios?
      self.portafolios.empty?  
   end
end

class Product < AR::Base
   belongs_to :enterprises
end

Now when you delete an enterprise this process validates if there are products associated with enterprises Note: You have to write this in the top of the class in order to validate it first.
